A review of the research on the supreme leader’s economic thought

  Since the 18th National Congress of the Communist Party of China, the CPC Central Committee with the Supreme Leader as the core has been far-sighted, comprehensively grasped the general trend of world development, profoundly summed up the experience and lessons of domestic and international development, creatively put forward a series of new ideas, new ideas and new strategies for governing the country and politics, founded and formed the economic thoughts of the Supreme Leader, scientifically guided China’s economic reform and development practice in the new era, and promoted historical achievements and changes in economic and social development. Facing the complicated situation since the outbreak of the COVID-19 epidemic, the CPC Central Committee with the Supreme Leader as the core coordinated the overall situation of the great rejuvenation strategy of the Chinese nation and the unprecedented changes in the world in the past century, led the country to achieve stable, sustained and healthy economic and social development with superb leadership, firm political belief and perseverance, and further enriched and developed the economic thought of the Supreme Leader in practice.

  Theoretical circles have actively carried out propaganda and interpretation and physical and chemical research around the formation and development of the supreme leader’s economic thought, and have made gratifying progress in both breadth and depth. Sorting out these research results will help us to understand the core essence and essence of the supreme leader’s economic thought more deeply, grasp the spiritual essence and value pursuit of the supreme leader’s economic thought more accurately, strengthen the ideological and theoretical arms more effectively and guide practice.

  First, the scientific theory of answering the question of the times

  The 19th National Congress of the Communist Party of China made a major judgment that "Socialism with Chinese characteristics has entered a new era". The new era calls for new theories, which lead to new practice. Socialism with Chinese characteristics’s entry into a new era is the prerequisite and the biggest development background for the supreme leader’s economic thought. Experts and scholars interpret the call of the new era for new economic ideas from different perspectives.

  First, from the perspective of the changes in the main social contradictions in China. In the new era, the main contradiction in our society is transformed into the contradiction between the people’s growing need for a better life and the unbalanced development. The development among regions, urban and rural areas and industries is still unbalanced, and the quality, efficiency and motivation of development need to be changed and upgraded. A series of new contradictions, problems and challenges in economic development urgently need new ideas to answer and solve.

  Second, from the perspective of changes in economic development stages. The new era means that China’s economy has shifted from a high-speed growth stage to a high-quality development stage. The stage of high-quality development pays more attention to better meeting the people’s growing needs for a better life. The new stage is facing new topics and needs new theories to guide it.

  Third, from the perspective of building a modern and powerful country. In the new era, the Chinese nation has ushered in a great leap from standing up, becoming rich and becoming strong. Building a modern and powerful country has become a realistic goal, which requires new economic development methods to support and new development concepts to guide.

  Fourth, from the perspective of problem orientation. The international situation is complex, severe and changeable, and the world is facing a great change that has never happened in a century. Global issues and world governance problems are prominent, which requires China to play a greater role and contribute to China’s wisdom and China’s strength. China’s economic and social construction has made great achievements, but it has also encountered some new problems and challenges. "The problem is the slogan of the times", "The times are the writers, and we are the respondents". In a certain sense, the supreme leader’s economic thought is produced to solve the problems of the times, and it is a new interpretation and new answer to the eternal theme of "development" in the new era.

  Second, profound ideological content

  (A) the new development concept and "seven adherences" are the main contents of the supreme leader’s economic thought.

  Before Socialism with Chinese characteristics’s economic thought in the new era of the Supreme Leader was formally put forward, scholars used "General Secretary of the Supreme Leader’s important exposition on economic work" and "Supreme Leader’s economic strategic thought". After General Secretary of the Supreme Leader put forward the concept of "new normal" during his inspection tour in Henan in May 2014, some scholars took "new economic normal" as an important content of research.

  In October 2015, the Fifth Plenary Session of the 18th CPC Central Committee adopted the Central Committee of the Communist Party of China’s Proposal on Formulating the Thirteenth Five-Year Plan for National Economic and Social Development, which put forward five development concepts of innovation, coordination, green, openness and sharing for the first time. In his speech at the second plenary session of the Fifth Plenary Session of the 18th CPC Central Committee, General Secretary of the Supreme Leader pointed out that the concept is the forerunner of action, the development concept is strategic, programmatic and leading, and it is the concentrated expression of development ideas, development direction and development focus. General Secretary of the Supreme Leader scientifically explained the logical relationship between the five development concepts: innovation and development focus on solving the problem of development motivation; Coordinated development focuses on solving the problem of unbalanced development; Green development focuses on solving the problem of harmony between man and nature; Open development focuses on solving the problem of internal and external linkage of development; Sharing development focuses on solving social fairness and justice problems. General Secretary of the Supreme Leader emphasized in many important speeches that the new development concept is a profound change that has a bearing on the overall development of our country.

  The Central Economic Work Conference held in December 2017 clearly pointed out: "In the past five years, we have persisted in observing the general trend, seeking the overall situation and doing practical things, successfully controlled the overall situation of China’s economic development, and formed the supreme leader’s new era Socialism with Chinese characteristics’s economic thought with the new development concept as the main content in practice." This is the first time that the central authorities put forward the concept of "Socialism with Chinese characteristics’s Economic Thought of the Supreme Leader in the New Era", and it is also the first formal formulation of a specific aspect of Socialism with Chinese characteristics Thought of the Supreme Leader in the New Era, from which we can see the important position of the Supreme Leader’s Economic Thought. The meeting pointed out that the economic thought of the supreme leader "takes the new development concept as the main content" and emphasized "seven persistences": persisting in strengthening the centralized and unified leadership of the party over economic work to ensure the development of China’s economy in the right direction; Adhere to the people-centered development thought, which runs through the overall layout of "five in one" and the coordinated promotion of "four comprehensive" strategic layout; Adhere to the adaptation and grasp the new normal of leading economic development, base on the overall situation and grasp the law; Insist on making the market play a decisive role in resource allocation, give better play to the role of the government, and resolutely remove institutional and institutional obstacles to economic development; Persist in adapting to the main contradictions and changes in China’s economic development, improve macro-control, make a choice according to the camera, and prescribe a correct prescription.Take promoting supply-side structural reform as the main line of economic work; Adhering to the problem-oriented deployment of the new strategy of economic development has a far-reaching impact on China’s economic and social development and reform; Adhere to the correct work strategies and methods, strive for progress steadily, maintain strategic strength, adhere to the bottom line thinking, and move forward step by step.

  There are two main generalizations of the economic thoughts of the Supreme Leader in theoretical circles: one is "1+7", where "1" refers to the new development concept and "7" refers to "seven persistences"; The other is directly summarized as "seven persistences". Most scholars hold the former view, and many discussions are generally within this range, although they are from different angles.

  (B) General Secretary of the Supreme Leader’s series of important theoretical judgments on the overall situation of China’s economic development

  In addition to the new development concept and the "seven adherences", many scholars have sorted out the theoretical judgments and strategic plans concerning the overall situation of China’s economic development, and believe that the following conclusions are also an important part of the supreme leader’s economic thought.

  First, adhere to the theory of the primary stage of socialism, adhere to the basic socialist economic system such as public ownership as the main body, the common development of various ownership economies, distribution according to work as the main body, the coexistence of various distribution methods, and the socialist market economic system. This is an important pillar of the Socialism with Chinese characteristics system and the foundation of the socialist market economic system.

  The second is to adhere to overall development and security. Adhere to the overall concept of national security, strengthen the national security system and capacity building, strengthen the national economic security guarantee, run security development through all fields and the whole process of national development, and prevent and resolve various risks and challenges that affect China’s modernization process.

  The third is to promote high-quality development, which is the theme of economic and social development in the new era. High-quality development is the general requirement for all aspects of economic and social development. It is necessary to embody the new development concept from supply, demand, input and output, distribution, macroeconomic cycle and other aspects to better meet the people’s growing needs for a better life.

  The fourth is to build a modern economic system, which is the strategic goal of China’s development. It is necessary to build an industrial system that is led by innovation and develops in coordination, an urban-rural regional development system that highlights advantages and is coordinated, a multi-balanced, safe and efficient all-round opening system, a unified, open and competitive market system, an efficient and fair income distribution system, a resource-saving and environment-friendly green development system, and an economic system that gives full play to the role of the market and the government. Several systems are a unified whole, which should be built and promoted as a whole.

  The fifth is to promote the supply-side structural reform, which is the main line of economic work at present and for a long time to come. The general requirement for promoting supply-side structural reform is to "consolidate, strengthen, upgrade and smooth", and the five major tasks of "de-capacity, de-inventory, de-leverage, cost reduction and short-boarding" are focused on. The fundamental purpose is to resolve various structural imbalances faced by China’s economic development, improve supply quality, and make supply capacity better meet people’s growing needs for high-quality life.

  Sixth, speed up the construction of a new development pattern with the domestic big cycle as the main body and the domestic and international double cycles promoting each other. The new development pattern defines the path choice of China’s economic modernization, emphasizes the domestic market, gives full play to the advantages of China’s ultra-large-scale market, and makes the domestic market and the international market better connected by exerting the potential of domestic demand on the basis of domestic demand leading and internal recycling.

  Seventh, promoting social fairness and justice and gradually realizing the common prosperity of all people are the essential requirements of socialism and the important goal of socialist modernization. It is necessary to promote common prosperity in high-quality development, focus on expanding the scale of middle-income groups, strengthen the regulation and adjustment of high income, promote the equalization of basic public services, promote the common prosperity of people’s spiritual life, and promote the common prosperity of farmers and rural areas.

  There are also scholars who specialize in studying the important expositions of the Supreme Leader’s General Secretary on some important issues, development concepts and strategic planning in specific fields, such as finance and taxation, real economy, digital economy, ecological economy, rural revitalization, regional coordination, global economic governance, the "Belt and Road Initiative" and the concept of a community of human destiny, which are also important components of the Supreme Leader’s economic ideology.

  Third, a strict and complete logical system

  Scholars comb the theoretical logic, historical logic and practical logic of the supreme leader’s economic thought from different perspectives in order to better grasp its core essence. The generalization of "1+7" has been widely recognized by theoretical circles. The new development concept occupies a leading position in the supreme leader’s economic thought, and the "seven persistences" as specific requirements and strategic measures are organically combined to form a complete ideological system with strict logic and rich content.

  It is generally believed that the logical starting point of the supreme leader’s economic thought is that Socialism with Chinese characteristics has entered a new era. Some scholars also believe that "people-centered" has a foundation and leading significance for the systematic construction and innovative development of the supreme leader’s economic thought. Other scholars advocate that the logical starting point is the change of major social contradictions.

  Some scholars use a judgment, a goal, five concepts, a main line, a method and a fundamental guarantee to summarize the theoretical framework of the supreme leader’s economic thought. A judgment means that China’s economy has changed from a high-speed growth stage to a high-quality development stage. One goal is to build a modern economic system. Five concepts, namely the new development concept. A main line refers to the supply-side structural reform as the main line of economic work. One method refers to the general tone of the work of striving for progress while maintaining stability. Fundamental guarantee refers to the party’s centralized and unified leadership over economic work.

  Some scholars have expounded the rich connotation, structure and logical system of the supreme leader’s economic thought from five dimensions: essentialism, axiology, epistemology, practice and methodology. Adhering to the party’s leadership is the most essential feature of Socialism with Chinese characteristics’s economy; Taking the people as the center highlights the value orientation of the supreme leader’s economic thought and clearly answers the question of "for whom does Socialism with Chinese characteristics’s economy develop" in the new era; The new normal is the key to know and understand the supreme leader’s economic thought; Insist on making the market play a decisive role in resource allocation, give better play to the role of the government, persist in promoting supply-side structural reform as the main line of economic work, persist in problem-oriented deployment of new economic development strategies, clarify the practical requirements and key points of Socialism with Chinese characteristics’s economic construction in the new era, and systematically answer the question of "how to achieve development"; It is an important methodological principle of the supreme leader’s economic thought to persist in striving for progress in stability and adhering to the bottom line thinking.

  As for how to grasp the economic thoughts of the supreme leader, some scholars pointed out that it is necessary to adhere to the integrity and systematicness, and to grasp the economic thoughts and views put forward by the general secretary of the supreme leader at different times since the 18 th National Congress of the Communist Party of China as a whole with internal relations and sustainable development.

  Fourth, rich and profound theoretical sources

  Scholars mainly trace the economic thought of the supreme leader from the following aspects.

  First, the theoretical basis of the supreme leader’s economic thought is Marxist political economy. From studying, studying and applying Marxist political economy to "adhering to the major principles of Socialism with Chinese characteristics’s political economy" and "constantly improving the theoretical system of Socialism with Chinese characteristics’s political economy", General Secretary of the Supreme Leader is the process of constantly China-izing and modernizing the basic principles of Marxist political economy and forming the economic thoughts of the Supreme Leader. The basic value orientation of "people-centered" and "development for the people" is based on adhering to Marxist labor theory of value.

  Second, the supreme leader’s economic thought is the inheritance and development of Mao Zedong Thought and Socialism with Chinese characteristics’s economic development thought. For example, correctly handle a series of major relations in economic and social development, adhere to the theory of the primary stage of socialism, adhere to the liberation and development of social productive forces, adhere to the theme of the times, adhere to the value orientation of maximizing people’s interests, adhere to the goal of building a well-off society in an all-round way and realizing modernization, adhere to the basic socialist economic system and establish and improve the socialist market economic system, adhere to strengthening the party’s leadership over economic work, adhere to the "national chess game", "overall consideration" and "striving for progress while being stable"

  Third, the supreme leader’s economic thought has absorbed the nutrition of Chinese excellent traditional culture. China’s thoughts on governance and development, which have been handed down for thousands of years, are often quoted by the Supreme Leader General Secretary in his speech and creatively applied to his practice of governing the country.

  Fourth, the supreme leader’s economic thought draws lessons from the beneficial components of western economics and profoundly summarizes the experience and lessons of contemporary capitalist economic development. In the 28th collective study in the Political Bureau of the Central Committee in 2015, General Secretary of the Supreme Leader pointed out that we adhere to the basic principles and methodology of Marxist political economy, and do not exclude the reasonable components of foreign economic theories. We should pay attention to learning from the aspects of western economics that reflect the general laws of socialized mass production and market economy, and at the same time, we should persist in removing the rough and selecting the fine, discarding the false and retaining the true, and take ourselves as the main factor and serve us.

  V. Solid and heavy practical foundation

  Scholars believe that tracing back to the practical source of the supreme leader’s economic thought mainly focuses on three aspects.

  First, the major measures and successful experiences of socialist construction since the founding of New China, especially since the reform and opening up. This is the practical source of Socialism with Chinese characteristics Theory, and the supreme leader’s economic thought is the inheritance and development of these outstanding achievements.

  Second, the great practice and brilliant achievements of Socialism with Chinese characteristics’s economic construction since the 18th CPC National Congress. Since the 18th National Congress of the Communist Party of China, the recovery of the world economy has been weak, local conflicts and turmoil have occurred frequently, and global problems have intensified. The CPC Central Committee with the Supreme Leader as the core has put forward a series of new ideas, new ideas and new strategies, promulgated a series of major principles and policies, launched a series of major initiatives, pushed forward a series of major tasks, solved many long-term unsolved problems, and made many major events that were tried but not done in the past, which promoted historic changes in the cause of the party and the state. This is the main practical basis of the supreme leader’s economic thought.

  Third, General Secretary of the Supreme Leader has extraordinary personal experience and rich political experience. Comrade Supreme Leader’s life experience as an educated youth in northern Shaanxi, which is in harmony with the yellow land and local people, has made him establish the belief of serving the people wholeheartedly and laid the foundation of people-centered economic thought. The exploration of the Supreme Leader’s leading local economic work during his stay in Hebei and Fujian is the practical accumulation of the formation of the Supreme Leader’s economic thought. Comrade Supreme Leader visited Jinjiang seven times when he was working in Fujian, and put forward "Six Persistences", including the ideas of always adhering to the development of social productive forces as the fundamental direction of reform and development and always adhering to the market-oriented economic development. The above practical wisdom was further deepened when Zhejiang and Shanghai were in power, and the "Eight-eighth Strategy" and "Lucid waters and lush mountains are invaluable assets" were put forward while working in Zhejiang. Long-term experience at the grass-roots level has enabled the Supreme Leader to accumulate rich experience in economic work, and have personal feelings and deep thoughts on issues concerning agriculture, rural areas and farmers, people’s livelihood, poverty alleviation, coordinated development, opening to the outside world, ecological environment and innovative development, which have become the direct practical basis for the formation of his economic thoughts.

  VI. Significant and profound theoretical innovations

  Scholars generally believe that the supreme leader’s economic thought is the theoretical crystallization of the combination of Marxist political economy and the concrete reality of China’s economic development, and it is the innovative achievement of Socialism with Chinese characteristics’s political economy, which breaks through the traditional barriers of western economics, expands the way for developing countries to move toward modernization, and contributes China’s wisdom and China’s plan to solving human problems.

  (A) the development and innovation of Marxist political economy

  The first is to solve some difficult problems in political economy. People-centered thought has developed Marx’s labor theory of value and dispelled some people’s doubts about whether the labor theory of value can support the value orientation of Socialism with Chinese characteristics’s market economy reform. Adhere to the idea of making the market play a decisive role in resource allocation and better play the role of the government, and solve the theoretical problem of whether public ownership and market economy can be unified. The idea of supply-side structural reform is a further deepening of Marxist political economy theory on productivity and production relations, and a new theory to promote the advanced development of productivity.

  The second is to enrich the new connotation of Marxist methodology. Insisting on problem orientation deepens the dialectical relationship between practice and cognition. Persisting in striving for progress in stability embodies the dialectical unity of movement and stillness, quantitative change and qualitative change, and is a vivid application and innovative development of materialist dialectics. Maintaining strategic strength is a creative application of contradiction analysis. Adhering to the bottom line thinking highlights the grasp of the stipulation of matter and matter, which is a major innovation in philosophical thinking mode.

  Third, the category of "Socialism with Chinese characteristics’s Political Economy" is a profound change in the theory of political economy. Comrade Deng Xiaoping once pointed out that the Decision of the Central Committee of the Communist Party of China on Economic System Reform adopted at the Third Plenary Session of the Twelfth Central Committee of the Communist Party of China "wrote a first draft of political economy, which is a combination of the basic principles of Marxism and the socialist practice in China". The Central Economic Work Conference held in December 2015 proposed that we should adhere to the major principles of Socialism with Chinese characteristics’s political economy, emancipate and develop social productive forces, and adhere to the direction of socialist market economy reform, so that the market can play a decisive role in resource allocation. The category of "Socialism with Chinese characteristics’s Political Economy" is a systematic summary and sublimation of Socialism with Chinese characteristics’s economic construction theory since the reform and opening up, and has opened up a new realm of Marxist political economy in contemporary China.

  (B) the development and innovation of Socialism with Chinese characteristics’s economic theory.

  First, judging the reality of economic development by the new orientation of China’s development history and the changes of major social contradictions, and making a new judgment that China’s economy has entered a new stage of development have become an important basis for determining the direction of macroeconomic policies.

  Second, the people-centered idea runs through the economic development in the new era and takes "accurate poverty alleviation" and "comprehensive well-off society" as the most important practical form in the contemporary era, which scientifically answers the question of "for whom to develop" and becomes the starting point and basic position of economic work.

  Third, the new concept of development is a new concept of development that can solve the practical problems faced by China’s economic development when Socialism with Chinese characteristics enters a new era, enhance the development momentum, cultivate development advantages and lead economic development.

  Fourth, it is a new breakthrough in the combination of socialism and market economy to insist on strengthening the centralized and unified leadership of the party over economic work and making the market play a decisive role in resource allocation and better play the role of the government.

  (C) breaking through the barriers of western economics

  The supreme leader’s economic thought draws lessons from the beneficial components of western economics, and has achieved breakthroughs and transcendence in many aspects.

  First, it breaks through the analytical paradigm of binary opposition between government and market in modern western mainstream economics.

  Second, adhering to the people-centered basic position is essentially to pursue the unity of fairness and efficiency in the process of economic growth, and then realize the all-round development of human beings, which transcends the assumption that the mainstream western economics takes profit maximization as the theoretical development premise, and avoids the resulting contradictions and various crises that the western economy continues to evolve.

  Thirdly, the emphasis on independence and taking the road of modernization in line with China’s national conditions enriches and develops the connotation of the road of modernization, and breaks through the theoretical assumption and guidance that "modernization" equals "westernization" implied in the context of mainstream western economics.

  Fourth, the supply-side structural reform is substantially different from the western supply school, which is an innovation and a major transcendence of the latter. The western supply school aims to solve the problem of stagflation, with large-scale tax reduction as the main means. The focus of supply-side structural reform in China is to liberate and develop social productive forces, promote structural adjustment, improve supply quality and improve total factor productivity, with the aim of making supply capacity better meet the growing, upgrading and personalized material, cultural and ecological environment needs of the broad masses of people.

  Fifth, it has surpassed the economic growth and development theory of western economics, and formed an economic development concept and road with China characteristics. It transcends the western theory of comparative advantage in international trade and the theory of factor endowment, and adheres to the principle of ensuring national autonomy and mutual benefit and win-win in opening up, thus breaking and crossing the "development trap" such as stagnation of economic growth, dependence of international division of labor and debt crisis.

  (D) Promote the reconstruction of the theory of international economic relations

  With the deepening of economic globalization, the interests and destinies of all countries in the world are more closely linked. World affairs need to be discussed and handled by all countries more and more, and global challenges need more and more cooperation from all countries. It is in this new situation that the Supreme Leader General Secretary put forward the idea of building a community of human destiny, demanding that the legitimate concerns of other countries be taken into account when pursuing their own interests, promoting common development of all countries in the pursuit of their own development, establishing a more equal and balanced new global development partnership, enhancing the common interests of mankind and jointly building a better home on earth.

  Some scholars have pointed out that "the community of human destiny" is a leading concept, which comprehensively promotes the original concepts in terms of international power, common interests, sustainable development and global governance, scientifically determines the basic starting point of international economic relations in the process of socialist modernization, and points out the path to solve global problems and promote global governance.

  Some scholars have pointed out that the construction of a "community of human destiny" can solve the problems of anti-globalization, populism and trade protectionism in the current globalization process, and better guide the new globalization to a fairer and more harmonious development path. This is a new and significant theoretical original contribution put forward by China in the light of the new global economic situation, which has promoted the reconstruction of the theory of international economic relations.

  Seven, a powerful weapon with great practical power

  The new era produces new ideas, which guide new practice. The supreme leader’s economic thought provides us with a fundamental follow-up and action guide for doing a good job in economic work. Some scholars have pointed out that there are several important points to understand the guiding significance of the supreme leader’s economic thought to the practice of economic work: first, to form the institutional mechanism of the party’s centralized and unified leadership over economic work; The second is to form an economic policy system guided by the new development concept; The third is to form an economic development idea with supply-side structural reform as the main line; The fourth is to form an economic work methodology of striving for stability, emphasizing scientific thinking such as problem-oriented and bottom-line thinking.

  Focusing on promoting high-quality development, the Central Economic Work Conference held in December 2017 put forward eight key tasks: deepening supply-side structural reform, stimulating the vitality of various market players, implementing rural revitalization strategy, implementing regional coordinated development strategy, promoting the formation of a new pattern of comprehensive opening-up, improving people’s livelihood, accelerating the establishment of a housing system with multi-agent supply, multi-channel guarantee and simultaneous rent and purchase, and accelerating the construction of ecological civilization. Some scholars attribute these measures to the practical path to realize the strategic goal of building a modern economic system.

  Scholars generally believe that since the 18th National Congress of the Communist Party of China, the historic achievements and changes in China’s economic development have benefited from the scientific guidance of the supreme leader’s economic thought and the successful practice of this important thought. The economic thought of the supreme leader gives a new answer to the question of "what kind of economic development to achieve and how to achieve it" in the new era. The new development concept and "seven adherences" provide a scientific practical guide for achieving higher quality, more efficient, fairer, more sustainable and safer development. Some scholars believe that the overall victory in the fight against poverty and the great achievements in building a well-off society in an all-round way have embodied the practical guidance of the supreme leader’s economic thought.

  The 2020 Central Economic Work Conference emphasized our regular understanding of doing a good job in economic work under severe challenges: the authority of the CPC Central Committee is the fundamental reliance of the whole party and the people of all ethnic groups in times of crisis; The supremacy of the people is the fundamental prerequisite for making a correct choice; Institutional advantage is the fundamental guarantee to form a powerful force to overcome the difficulties; Scientific decision-making and creative response are the fundamental methods to turn crisis into opportunity; Self-reliance of science and technology is the fundamental support to promote the overall development. Some scholars believe that these summaries made by the Central Economic Work Conference on the reasons for China’s great achievements in epidemic prevention and control and economic and social development under the grim situation have profoundly revealed the great practical guiding significance of the supreme leader’s economic thought to economic work.

  Eight, distinctive theoretical character

  Scholars have reached the following consensus on some distinctive characteristics of the supreme leader’s economic thought.

  One is political. Politics is the fundamental quality of the supreme leader’s economic thought, which is embodied in "adhering to the socialist direction" and "adhering to the party’s centralized and unified leadership over economic work" Taking the political system as an important factor, we pay attention to expounding the relationship between politics and economy and the role of politics in economy, so as to make the supreme leader’s economic thought a "political economy" with distinctive China characteristics, China style and China style.

  The second is people’s nature. Adhering to the people as the center is the foothold of the supreme leader’s economic thought, and it is a theoretical principle that not only embodies the party’s fundamental purpose and position, but also runs through the overall layout of "five in one" and the coordinated promotion of "four comprehensive" strategic layouts, and is implemented in all aspects of economic development.

  The third is scientific. The economic thought of the Supreme Leader is a theoretical system that leads the high-quality development of China’s economy and society on the basis of inheriting and developing Marxist political economy and Socialism with Chinese characteristics’s economic theory and scientifically analyzing the new changes in China’s economic and social development in the new era. It contains profound academic rationality, rich connotation and rigorous logic.

  The fourth is practicality. The formation of the supreme leader’s economic thought has a profound practical foundation, which comes from practice, comes from answering practical topics in the new era and develops in practice. This thought is full of practical wisdom, which plans the practical path of building a modern economic system and realizing the goal of "two hundred years", which is the fundamental follow-up of the party’s leading economic work.

  The fifth is cosmopolitan. The supreme leader’s economic thought embodies the common value pursuit of mankind. Insisting on improving people’s well-being and promoting people’s all-round development as the starting point and end result of economic development reflects the common aspiration of mankind for a better life. Committed to peaceful development, emphasizing mutual benefit and sharing, actively participating in global economic governance and building a community of human destiny reflect the common aspiration of human beings for peaceful development, equal development and common development.

  Some scholars believe that the distinctive features of the Supreme Leader’s economic thought are: the theoretical character of keeping pace with the times, the core essence of comprehensively deepening reform, the value pursuit of the great rejuvenation of the Chinese nation and the remarkable improvement of people’s living standards, a clear understanding of China’s economic and social development goals and roads, and an unswerving pursuit of modernization in line with China’s national conditions.

  Nine, make a significant contribution to the construction of Socialism with Chinese characteristics’s political economy.

  In November 2015, General Secretary of the Supreme Leader emphasized in the 28th collective study in the Political Bureau of the Central Committee that we should base ourselves on China’s national conditions and our development practice, reveal new features and laws, refine and summarize the regular achievements of China’s economic development practice, turn practical experience into systematic economic theory, and constantly open up a new realm of Marxist political economy in contemporary China. In July, 2016, General Secretary of the Supreme Leader presided over an expert symposium on economic situation, stressing that to uphold and develop Socialism with Chinese characteristics’s political economy, we should take Marxist political economy as the guide, sum up and refine the great practical experience of China’s reform, opening up and socialist modernization, and learn from the beneficial elements of western economics. In May 2017, the Central Committee of the Communist Party of China issued the Opinions on Accelerating the Construction of Philosophy and Social Sciences with China Characteristics, proposing to accelerate the construction of the discipline system of philosophy and social sciences with China characteristics. A series of important expositions made by the Supreme Leader General Secretary provided a fundamental basis for the construction of Socialism with Chinese characteristics’s political economy, and scholars had a heated discussion on how to build and develop Socialism with Chinese characteristics’s political economy.

  The first is about the basic principles that should be adhered to in the construction of Socialism with Chinese characteristics’s political economy. Scholars put forward that we must base ourselves on the primary stage of socialism and reflect the characteristics of the times, which is the general basis for building Socialism with Chinese characteristics and the basis for Socialism with Chinese characteristics’s political economy. Under the guidance of Marxism, we should absorb the important achievements of Socialism with Chinese characteristics’s economic theory and draw lessons from foreign economic theories reasonably. Some scholars put forward that adhering to the principle of liberating and developing productive forces is the basic method and principle of developing and applying Socialism with Chinese characteristics’s political economy, and emphasized that the theory of socialist market economy should occupy an important position in Socialism with Chinese characteristics’s political economy theory system.

  The second is about the research object of Socialism with Chinese characteristics’s political economy. Some scholars believe that it should be consistent with the classical Marxist political economy, and take the relations of production as the research object. Some advocate taking the mode of production as the research object, while others emphasize the national characteristics of Socialism with Chinese characteristics. Some scholars believe that Socialism with Chinese characteristics’s political economy studies the laws of production, exchange and distribution in the primary stage of socialism in China, which contains national and historical characteristics.

  The third is about the theme and theoretical logic of Socialism with Chinese characteristics’s political economy. Some scholars believe that Socialism with Chinese characteristics’s political economy is to solve a series of outstanding contradictions and problems faced by China’s development, and development is the core theme. The main content of the supreme leader’s economic thought "one idea plus seven persistences" is also the theoretical logic of Socialism with Chinese characteristics’s political economy. Some scholars have suggested that adhering to the people-centered development thought has established the main line for the construction of Socialism with Chinese characteristics’s political economy, and the idea of handling the relationship between the government and the market has established the basic paradigm for the allocation of Socialism with Chinese characteristics’s political economy research resources.

  The fourth is about the function of Socialism with Chinese characteristics’s political economy. Some scholars have pointed out that there should be a clear division of labor and boundary division among some disciplines in Socialism with Chinese characteristics’s theoretical system of economic construction, and to achieve a breakthrough in theoretical system construction, it is necessary to clearly divide the disciplinary boundaries of Socialism with Chinese characteristics’s economic construction at the three levels of "guiding ideology", "basic principles" and "realistic economic policy research", so as to play their respective roles.

  Ten, to further promote the research to go deep and practical.

  (A) the supreme leader’s economic thought research has achieved remarkable results.

  The theoretical research on the supreme leader’s economic thought is vigorous, effective and has a good momentum, which is mainly reflected in the following two aspects.

  First, important domestic units and departments set up specialized research institutions, which provided strong support for in-depth research on the economic thought of the supreme leader.

  Since 2017, the Central Committee of the Communist Party of China has successively approved the establishment of 18 research centers (institutes) for Socialism with Chinese characteristics Thought of the Supreme Leader in the New Era. In 2017, the Central Party School, Ministry of Education, China Academy of Social Sciences, National Defense University, Beijing, Shanghai, Guangdong, Peking University, Tsinghua University and China Renmin University, 10 units were approved. In July 2020, the Ministry of Foreign Affairs was approved. In June, 2021, 7 units from National Development and Reform Commission, Ministry of Ecology and Environment, china law society, Jiangsu, Zhejiang, Fujian and Shandong were approved. The National Development and Reform Commission established the Research Center of the Supreme Leader’s Economic Thought, which is a specialized institution for studying the economic thought of the Supreme Leader, with more than 40 governing units.

  In addition to the above-mentioned research institutions approved by the central government, some localities and many colleges and universities have also set up research institutions on Socialism with Chinese characteristics Thought of the Supreme Leader in the New Era. These research institutions give full play to their respective advantages to study the Supreme Leader’s Socialism with Chinese characteristics Thought in the new era, each with its own emphasis and characteristics, and it is one of their important responsibilities to carry out the research on the Supreme Leader’s economic thought.

  Second, a large number of national social science fund projects were approved and a large number of high-level research results were published, laying the foundation for further deepening the study of the supreme leader’s economic thought.

  According to the national social science fund project database, there are many topics whose project names contain the key words of the top leaders’ economic thoughts, such as: new development concept, people-centered, new economic normal, making the market play a decisive role in resource allocation and giving better play to the role of the government, high-quality development, supply-side structural reform, rural revitalization, Belt and Road Initiative, and community of human destiny.

  Searching from China HowNet and the national library’s collection catalogue, the main content of the supreme leader’s economic thought is the key word, and many works are searched out, specifically from different regions, industries and fields. Judging from the publication of the paper, there are many related articles, most of which are in 2018 and 2019, with "the economic thought of the supreme leader" as the keyword search. The number of detailed research papers increased rapidly in 2020 and 2021, among which "high-quality development" and "Belt and Road" were the most, followed by "supply-side structural reform", "new development concept" and "new development pattern".

  (B) Further promoting the study of the supreme leader’s economic thought has a long way to go.

  The research on the supreme leader’s economic thought has achieved gratifying results and deepened the understanding of a series of related important issues. However, because this idea has not been established for a long time, and it is in the process of continuous enrichment and development, there are still some shortcomings in the theoretical circle in terms of overall grasp, systematic understanding and deepening research, and it is a long way to go to further promote research.

  From the previous review of the projects approved by the National Social Science Fund and the publication of research works, it can be seen that the projects and works titled "Economic Thought of the Supreme Leader" or "Economic Thought of Socialism with Chinese characteristics in the New Era of the Supreme Leader" are rarely seen, indicating that there are not many systematic and weighty research results.

  Judging from the published articles, there are still some shortcomings in the current research. First, the integrity of the theoretical system of the supreme leader’s economic thought is not combed enough, and the grasp is not in place. Second, there are many general descriptions of the important expositions of the Supreme Leader General Secretary and macro explanations of the theoretical concept itself, and there are many problems in the research, but there is not enough in-depth research on the historical and practical origins of this idea and the elements of the theoretical system. Third, there is insufficient research on how the supreme leader’s economic thought is implemented in economic work practice and guided practice. Fourthly, the world significance of this thought has not been studied deeply. Fifth, most of the researchers come from Marxist theoretical disciplines and economic disciplines, while other disciplines such as politics, sociology, management and history are relatively weak.

  (C) Some suggestions for further research.

  The supreme leader’s economic thought comes from the practice of China’s socialist modernization, and is constantly enriched and developed in practice. Therefore, the study of this thought is a long-term and systematic project that needs to be deepened and refined continuously. Deepening the research faces an important task, that is, presenting the theoretical system of the supreme leader’s economic thought accurately, completely and systematically, and strengthening the guiding significance of the supreme leader’s economic thought to economic work. Therefore, in the future research work, we need to focus on the following issues.

  First, strengthen systematic research and grasp the theoretical system as a whole. The supreme leader’s economic thought is rich and profound. In order to accurately understand and present it completely, it is necessary to further trace the theoretical and practical sources of the supreme leader’s economic thought, deeply understand its value pursuit and practical goal, accurately grasp its core connotation, straighten out its theoretical framework and logical relationship, comprehensively grasp its scientific thinking methods and working methods, and clarify its theoretical innovation, practical guiding significance and world value.

  Second, coordinate the research at macro, meso and micro levels. The supreme leader’s economic thought is composed of various and multi-level concrete ideas. The research must go deep into these specific levels and deeply understand the problem consciousness, theoretical connotation and practical direction of these new ideas and strategies.

  Third, carry out in-depth investigation and study, and strengthen the summary of the supreme leader’s economic thought practice. Paying attention to the guiding role of theory in practice and the test of theory by practice can help us realize the practical value of the supreme leader’s economic thought more effectively, thus further enhancing our understanding of scientific theory. Since the end of 2020, Economic Daily has carried out in-depth research on the practice of the supreme leader’s economic thought nationwide, published a large number of high-quality research reports, displayed the implementation of the supreme leader’s economic thought and innovative measures in various places, and summarized and popularized successful experiences. This work is worthy of continuous and in-depth promotion on a larger scale.

  Fourth, strengthen interdisciplinary research. The supreme leader’s economic thought is the latest achievement of Marxism in contemporary China, which includes political, economic, social, cultural, historical, ecological and other fields, and reflects the development of China and the world. Multidisciplinary perspectives and multidimensional research methods are conducive to the expansion and deepening of research.

  Fifth, speed up the construction of Socialism with Chinese characteristics’s political economy. Guided by the series of important expositions of the Supreme Leader’s General Secretary, the discussion on the principles and framework of Socialism with Chinese characteristics’s political economy will enter the stage of discipline entity construction as soon as possible, so that Socialism with Chinese characteristics’s political economy will form a strong support for the study of the Supreme Leader’s economic thought in terms of disciplines, institutions and talents.

  Sixth, increase the external publicity and interpretation of the supreme leader’s economic thought. The new development concept and the concept of community of human destiny put forward by the Supreme Leader have profoundly influenced people’s views on the world, relations between countries and human development. China’s great achievements in poverty reduction have made great contributions to global poverty reduction, and the China route of economic modernization has contributed China’s wisdom and China’s plan to the international community. We should make greater efforts to tell the story of China from the perspective of theoretical research, so that the world can understand China more comprehensively, stereoscopically and objectively, and make a peaceful, progressive and prosperous China better benefit the world.

2019 ingenious keywords: the college entrance examination admission rate is over 80%, and the physical status is improved.

  For a long time, the college entrance examination has been an important topic of concern to all students and parents. Nowadays, the college entrance examination enrollment in 2019 has entered the final stage of volunteering. So, what is the development trend of the college entrance examination in 2019?

  Recently, China Education Online released the "Report on 2019" (hereinafter referred to as the "Report"), showing that the number of applicants for the college entrance examination in 2019 exceeded 10 million, and the actual admission rate of the national college entrance examination in 2018 reached 81.13%, with some areas exceeding 90%. At the same time, with the deepening of the reform process of college entrance examination, the Ministry of Education has standardized special types of enrollment, tightened the policy of independent enrollment, and some colleges and universities plan to reduce their enrollment by over 60%.

  The number of applicants for the college entrance examination exceeded 10 million, and the actual admission rate exceeded 80%

  In 2019, the number of applicants for the college entrance examination returned to the order of 10 million again after 10 years.

  According to the latest data released by the Ministry of Education, the number of applicants for the national college entrance examination in 2019 was 10.31 million, once again exceeding 10 million, setting a record high since 2010. However, since 2007, the actual admission rate of college entrance examination has been on the rise.

  According to the Report, the actual admission rate of college entrance examination exceeded 80% in 2017, which also means that most college entrance examination students have the opportunity to receive higher education. In 2018, there were 7,909,900 college students enrolled nationwide, an increase of 3.87% over the previous year, and the actual admission rate of college entrance examination reached 81.13%. Although the actual admission rate of college entrance examination in some areas has declined slightly, it still remains at a high level. In addition, the actual admission rate of college entrance examination in some areas exceeds 90%, such as Hebei and Jiangsu.

  It is worth noting that in recent years, the unfinished enrollment plan in some areas is more prominent. According to the "Report", taking Jiangsu and Hebei as examples, the number of unfinished enrollment plans in Jiangsu reached 42,000 in 2016, and it was controlled at around 20,000 in 2017 and 2018; The number of people who did not complete the enrollment plan in Hebei reached 28,000 in 2014, but it has dropped back to 0.75 million in 2017.

  With the continuous expansion of the scale of higher education, higher education will enter the stage of popularization. According to the Report, China has built the largest higher education system in the world, and the gross enrollment rate of higher education has increased rapidly, which is about to enter the stage of popularization. In 1978, the gross enrollment rate of higher education was only 1.55%, and in 2002, it increased to 15% in just 24 years, from the elite stage to the popular stage.

  The policy of special enrollment in colleges and universities is tightening

  With the deepening of the reform process of college entrance examination, the Ministry of Education has made efforts to promote fair and scientific talent selection, and standardized special types of enrollment.

  Many people call 2019 the "strictest" year in the history of independent enrollment. The Ministry of Education has made 10 strict requirements for independent enrollment, one of which is fairness and justice, and strictly controlling the enrollment scale.

  According to the Report, in previous years’ independent enrollment, the actual enrollment of most colleges and universities was lower than the enrollment plan. In 2018, among the 79 self-enrollment colleges and universities that publicized the enrollment information, 76 colleges and universities did not complete the self-enrollment plan, with a total vacancy of more than 5,200. Through the data sampling of 70 colleges and universities that carry out independent enrollment, only two colleges and universities have the same plans as last year, and the rest have reduced their plans. Among them, the independent enrollment plans of 13 schools have been reduced by 60%, and Shanghai University has been reduced by 80%.

  In addition, in 2019, the requirements for independent enrollment in colleges and universities generally increased. According to the Report, the minimum requirements for independent enrollment in Tsinghua and Peking University in 2019 have been significantly improved, and the scope of target students has been narrowed, and the maximum preferential margin has also dropped from 60 points in 2018 to 20 points. Physical fitness test has become a "standard" for independent enrollment assessment in colleges and universities. Twenty-six colleges and universities clearly stipulate in their independent enrollment brochures that failing to participate in the physical examination or failing to pass the physical examination results will affect the candidates’ independent enrollment qualifications.

  With the deepening of the college entrance examination reform, the pilot work of comprehensive evaluation reform is gradually launched, the scope is constantly expanding, and the number of students enrolled is also rising. According to incomplete statistics in the Report, in 2019, a total of 99 colleges and universities across the country conducted comprehensive evaluation enrollment pilots, among which 14 colleges and universities conducted comprehensive evaluation enrollment for multiple regions, and the remaining 85 colleges and universities conducted comprehensive evaluation enrollment in their provinces.

  It is worth noting that comprehensive evaluation has become the main enrollment method of individual colleges and universities. According to statistics, in 2018, among the nine ministries and commissions and universities from other provinces that implemented the "Trinity" comprehensive evaluation of enrollment in Zhejiang, the total number of "Trinity" enrollment plans of eight universities except Zhejiang University was 1,014, and the total number of unified enrollment plans of these eight universities was only 78.

  Nowadays, the threshold for sending students is further improved. The "Report" pointed out that since 2014, the number of students who have been admitted to the country has started to slim down significantly, and it has been declining for five consecutive years; The number of students who walked in decreased from 6,759 in 2013 to 2,091 in 2018 (excluding heroic children and retired athletes). The number of colleges and universities that recruit students who are recommended to walk has also decreased to 78 in 2018.

  The reform of college entrance examination has been promoted to the central and western regions, and its physical status has risen.

  In April 2019, the third batch of college entrance examination reform plans for eight provinces and cities were finally announced. The scope of this pilot project has been further expanded to the central and western regions. According to the "Report", from the perspective of the number of applicants, the total number of candidates in the six provinces and cities started before, except Shandong and Zhejiang, is relatively small. The provinces and cities started this time are basically big provinces for college entrance examination, and the number of candidates is huge.

  It is understood that the third batch of college entrance examination reform programs in eight provinces and cities is different from the previous six provinces and cities. The subject selection mode has changed from "3+3" to "3+1+2", and physics and history are the first choice subjects, so one must be selected; When enrolling students, plan, underline, file and enroll separately according to physical and historical categories. This move emphasizes the basic position of physics and history, and is expected to solve the problem of the decline in the number of physics candidates during the implementation of the college entrance examination reform plan in other provinces.

  In this regard, the "Report" analysis pointed out that students who choose physics subjects will have more choices and guide more students to choose physics.

  According to the Report, the six provinces and cities that initiated the reform of college entrance examination have announced the requirements for the selected subjects of college enrollment majors in 2020. Among them, the number of majors requiring required physics has increased significantly. Take the requirements of major selection in 2020 in 40 local undergraduate colleges in Shanghai as an example. A total of 558 majors involve the requirements of taking physics exams, among which 380 majors must choose physics, while only 65 majors must choose physics in 2017.

  Based on the basic position of physics in scientific research, high-level universities often pay more attention to physics. By analyzing the top 10 universities in China, namely, the Nine Schools Alliance (C9) and the University of Chinese Academy of Sciences, the Report found that 7 universities required physics majors to account for more than 50%. Among them, physics is required for all majors in China University of Science and Technology, and the proportions of Chinese Academy of Sciences, Harbin Institute of Technology, Xi ‘an Jiaotong University, Zhejiang University, Tsinghua University and Shanghai Jiaotong University are 76.92%, 74%, 72.72%, 72.2%, 60% and 51.16% respectively.

Starry sky keeps walking-"Five-hundred-meter Aperture Spherical Radio Telescope (FAST)" provides "China wisdom" for world astronomy.

  On April 17th, the reporter learned from the FAST Operation and Development Center of the National Astronomical Observatory that more than 900 new pulsars have been discovered by the 500-meter spherical radio telescope (FAST) known as the "Five-hundred-meter Aperture Spherical Radio Telescope (FAST)".

  Produce a series of world-class achievements in the fields of the origin of fast radio bursts and gravitational wave detection; Independent research and development of receiver core components is expected to go abroad; FAST core array construction is ready to go … …

  Staring at the starry sky, I kept walking. "Five-hundred-meter Aperture Spherical Radio Telescope (FAST)" is constantly providing China wisdom to the world astronomy and China technology to the global engineering community.

  Frequent achievements

  "Five-hundred-meter Aperture Spherical Radio Telescope (FAST)" is a well-known national weapon. In order to "produce early results, produce more results, produce good results and produce great results", China scientists constantly "challenge the limits of cognition and technology" and polish their profound "eyes" with "Creation by China".

On April 17th, the reporter got news from the FAST Operation and Development Center of the National Astronomical Observatory of the Chinese Academy of Sciences that the number of new pulsars discovered by the 500-meter spherical radio telescope (FAST), known as the "Five-hundred-meter Aperture Spherical Radio Telescope (FAST)", exceeded 900. Xinhua News Agency issued Liu Xu Lu Yuhan’s establishment

  Up to now, Five-hundred-meter Aperture Spherical Radio Telescope (FAST) has discovered more than 900 new pulsars, including at least 170 millisecond pulsars, 120 binary pulsars and 80 faint occasional pulsars.

  "We are expanding the cognitive limits of human beings to the universe." Han Jinlin, head of the galactic plane Pulsar Survey Project of the National Astronomical Observatory, said. In the 50 years from the discovery of the first pulsar by humans to the discovery of the first pulsar by FAST, less than 3,000 pulsars have been discovered in the world.

  On October 10th, 2017, Five-hundred-meter Aperture Spherical Radio Telescope (FAST) announced the discovery of six new pulsars, achieving a "zero breakthrough". This is the first time that China has discovered pulsars with its own independently developed radio telescope.

  At present, more than 900 new pulsars have been discovered by Five-hundred-meter Aperture Spherical Radio Telescope (FAST), which is more than three times the total number of pulsars discovered by other telescopes at the same time in the world.

  Among them, compared with the normal pulsars, the radiation flux density of 80 faint occasional pulsars is one order of magnitude lower, and the lowest one has reached the submicrocentric order.

  In Han Jinlin’s view, the study of these accidental pulsars is of great significance for understanding how many dense neutron star wrecks are formed after the death of stars in the Milky Way and revealing the unknown physical process of pulse radiation.

  Han Jinlin told reporters that if searching for pulsars is compared to picking fruits, all the pulsars discovered before are close to the ground and easy to "pick", while the more than 900 new pulsars discovered by Five-hundred-meter Aperture Spherical Radio Telescope (FAST) are farther away or more difficult to pick.

  Because each pulsar has its own special pulse and stable rotation frequency, they are equivalent to the "lighthouse" with unique signal marks in the universe. If the Interstellar can be realized in the future, these pulsars will provide "navigation" for human beings to travel in the vast universe.

  "We accurately measure the coordinates of pulsars in space, and monitor the phases and corresponding positional relationships of multiple pulsar signals during the journey, so that humans will not get lost in interstellar travel." Han Jinlin said.

  It is the first time to observe the "pulse" of black hole in radio band, detect the key evidence of the existence of nanohertz gravitational wave, and detect and construct the world’s largest neutral hydrogen galaxy sample … … In recent years, "Five-hundred-meter Aperture Spherical Radio Telescope (FAST)" has made China contributions to exploring the mysteries of the universe.

  In the face of the unknown and the future, human destiny is shared. From the moment it was born, "Five-hundred-meter Aperture Spherical Radio Telescope (FAST)" shouldered the mission.

  Sun Chun, the measurement and control engineer of Five-hundred-meter Aperture Spherical Radio Telescope (FAST), introduced that since it was officially opened to the global scientific community on March 31st, 2021, Five-hundred-meter Aperture Spherical Radio Telescope (FAST) has helped research teams from 15 countries including the United States, the Netherlands and Australia to carry out observation for nearly 900 hours, covering many fields such as scientific target drift scanning survey, neutral hydrogen galaxy survey, galaxy polarization survey, pulsar time measurement, and rapid radio burst observation.

  In the foreseeable future, "Five-hundred-meter Aperture Spherical Radio Telescope (FAST)" will bring more new perspectives for the international astronomical community to continue to explore the universe and try to find the unknown, and make greater contributions to leading mankind to break through the new field of cognition.

  Innovation is not limited.

  "I thought it would be revised seven or eight times, but I didn’t expect the performance of the first edition to reach the world advanced level." Chai Xiaoming, a senior engineer at the National Astronomical Observatory of the Chinese Academy of Sciences, introduced to the reporter a low-noise amplifier with a silver-plated shell and only the size of an organ. It was hard to hide his excitement in his speech.

  Low noise amplifier is the core component of Five-hundred-meter Aperture Spherical Radio Telescope (FAST) receiver, which was imported before.

  In order to solve the problem of "stuck neck" and master the key technology in their own hands, Chai Xiaoming’s team spent nearly two years independently developing this high-performance domestic low-noise amplifier.

  Once the prototype was launched, it attracted the attention of the international astronomical community. The BINGO project in Brazil first proposed the willingness to cooperate in bulk purchase to the FAST Operation and Development Center.

  As the largest and most sensitive single-aperture spherical radio telescope in the world, "Five-hundred-meter Aperture Spherical Radio Telescope (FAST)" has stimulated many special technical requirements, which requires China scientists to give full play to their subjective initiative and creativity, and to optimize and upgrade by constantly "challenging the cognitive and technical limits" and constantly "discovering and solving problems".

  There is no shortcut to innovation, only dare to climb.

  "No one told you what to do, and no one was sure that his own method would work." Jiang Peng, executive deputy director and chief engineer of FAST Operation and Development Center, said that the difficult research of "trial and error, failure and courage" runs through almost every link of FAST construction stage.

  In order to solve the problem of cable fatigue, Jiang Peng led a group of young people through nearly 100 failures and successfully supported the "retina" of "Five-hundred-meter Aperture Spherical Radio Telescope (FAST)".

  In order to develop a new control system, Sun Jinghai, director of the Measurement and Control Engineering Department of FAST Operation and Development Center, burned the midnight oil to the east for countless times and almost rewritten all the core algorithm codes.

  In order to solve the problem of electromagnetic interference in substations, Gan Hengqian, director of the Electronic and Electrical Engineering Department of FAST Operation and Development Center, invented &hellip, a high-voltage filter matching with Five-hundred-meter Aperture Spherical Radio Telescope (FAST), after nearly two years of exploration and testing. …

  Only in the construction stage, "Five-hundred-meter Aperture Spherical Radio Telescope (FAST)" won important scientific and technological awards in more than ten fields, such as steel structure, automation industry, machinery industry, surveying and mapping geographic information technology, and electromagnetic compatibility research and development.

Panorama of "Five-hundred-meter Aperture Spherical Radio Telescope (FAST)" taken on February 26th, 2024 (photo of UAV, taken during maintenance). Xinhua News Agency reporter Ou Dongyu photo

  "Eye of the Sky" asks the sky, and there is no end. Jiang Peng said frankly that if FAST is only regarded as a telescope and a monitoring device, it has reached the standard now. However, to maintain the leading position of FAST in the world, our innovation cannot stop, and we will do our best to make FAST more stable and efficient.

  At present, the annual observation time of FAST is stable at about 5,300 hours, which plays an important supporting role in continuously outputting scientific research results.

  Compete for the future

  Explore the sky and decipher the stars. "Five-hundred-meter Aperture Spherical Radio Telescope (FAST)" has never stopped innovating.

  "Astronomy is extremely romantic, because it studies the sea of stars of human beings. Astronomy is also extremely cruel, because international competition is extremely fierce, and once it is relaxed, it will lose its leading position. " Jiang Peng said.

  Looking around the world, many radio telescope arrays, such as SKA, are under construction.

  "Once these telescopes are put into operation, ‘ Five-hundred-meter Aperture Spherical Radio Telescope (FAST) ’ Will face enormous challenges. " Jiang Peng said, "If we relax a little, China astronomers may ‘ Lost ’ The forefront of the radio band field of vision. "

  The reporter recently walked into the core area of "Five-hundred-meter Aperture Spherical Radio Telescope (FAST)" and saw on a hill less than 3 kilometers away from "Five-hundred-meter Aperture Spherical Radio Telescope (FAST)" that the excavator was working intensively, and the original jagged hill top with miscellaneous trees had been leveled and compacted.

  "We plan to use the excellent electromagnetic wave environment within 5 kilometers around FAST in the next five years to build 20 to 30 fully movable radio telescopes with a diameter of 40 meters, and form a comprehensive aperture array with FAST, that is, the FAST core array." Jiang Peng told reporters that a 40-meter-class fully movable radio telescope will be built on the working hill within this year.

  "By ‘ Five-hundred-meter Aperture Spherical Radio Telescope (FAST) ’ Observing the universe is like using ‘ Thick-headed pencil ’ If the core array is completed and put into use, it is equivalent to using high-resolution ‘ Digital camera ’ Shoot the distant stars. " Jiang Peng introduced that once the core array is completed, it will greatly improve the vision of "Five-hundred-meter Aperture Spherical Radio Telescope (FAST)" and let "‘ Five-hundred-meter Aperture Spherical Radio Telescope (FAST) ’ Not only can you see far, but you can also see clearly. "

  According to AARON Li, director of the Structural and Mechanical Engineering Department of FAST Operation and Development Center, FAST Core Array will expand the existing scientific research fields, especially play an important role in extreme temporary sources such as gravitational wave events, fast radio bursts, gamma ray bursts, supernovae and black hole tidal disintegration events.

  In addition to astrophysical research, FAST core array is expected to play a huge role in the field of deep space exploration, such as near-earth object early warning, space micro-target detection, deep space satellite communication and control, ionospheric characteristics measurement, pulsar time reference, etc., which can play a very important strategic support role for the development of China’s aerospace field.

  Jiang Peng said: "In order to keep China’s radio astronomy power internationally advanced, we will accelerate the climb from a new starting point and lead the team to explore new scientific frontiers."

Secret history of fresh meat moon cakes in Shanghai beach

Original Han Xiaoni’s guide to Shanghai residents’ life is included in the topic # Time-honored brand 1# Fresh meat moon cake 1.

The "moon cake season" is here again. The surging fresh meat moon cake industry in Shanghai is launching a new round of queuing time competition.

In fact, behind the uproar, Shanghai’s time-honored brands have many "secrets" about fresh meat moon cakes.

Where to start with too much material? Why don’t we start with the story of "Rashomon" between Guangming Village, Changchun and Harbin, the "Big Three" on Huaihai Road?

one

A long queue of fresh meat moon cakes in Guangming Village

Aunt, uncle and uncle came prepared.

I brought all the benches.

The Guangming Village on Huaihai Road is still in the same style this year, and the long queue to buy fresh moon cakes these days has been lined up to "Popeyes".

In fact, as early as late August, more than a month before the Mid-Autumn Festival, we found that this team "re-emerged".

A pot of 65 moon cakes and five boilers started in unison. In the afternoon of the working day, the long queue to buy moon cakes still blocked the alley next door.

An uncle in a white Polo shirt and a briefcase with one shoulder just squeezed out of the crowd and carried four boxes of fresh meat moon cakes in his hand.

"Allah’s age is more meticulous (careful), and I came to make a sample yesterday. I have to wait for an hour and a half in the morning, and the salesperson said that there will be fewer people in the next half day (afternoon). "

"I came over today to see that the team was quite long, and I bought it in less than 10 minutes."

"In fact, it is the most cost-effective to buy now, and you don’t suffer from queuing." My uncle is happy to share his "wrong peak" buying experience.

As early as late August,

Many customers came.

Cuofeng bought moon cakes.

"My name is lu, lu wan district. I am old Luwan, and buying this (moon cake) is nostalgic. " He said.

It turns out that the 73-year-old Lao Lu was born in Le ‘anfang opposite Guangming Village.

He came here to buy four boxes of moon cakes because there are four brothers and sisters, and he is going to send a box to the family.

Fresh meat moon cakes on Shanghai beach can be roughly divided into boiler pie and oven pie.

Lao Luting boiler pie. He said: "Now most of them are baked in the oven, and the baked grains are round, like steamed bread. Biting down is all flour, and it is stiff, indicating that the pastry is not done well. "

The fresh meat moon cakes in Guangming Village are baked in the boiler. "Its skin is crispy, and when you hold it in your hand, it looks like snowflakes layer by layer."

Belong to the "boiler school"

Both sides of the moon cake are flat.

I have bought it for many years, and Lao Lu even knows the "inheritance" of his mooncake skills clearly.

"It turned out that an old master was doing it himself in the first generation, and it was always good to eat the minced meat."

"We belong to the mouth is a knot in one’s heart. After the old master retired two years ago, we found that there was sugar in the stuffing, which was not delicious. Fortunately, it was changed back immediately after one year. "

"Now are two aunts in the roast. However, I think the master’s’ True Sutra’ has basically been handed down. "

Auntie used a pan.

In Shanghai’s "Fresh Meat Moon Cake List" commented by the public, Guangming Village currently tops the list and stands at the top of the contempt chain.

However, in the middle section of Huaihai Road (), which is characterized by cakes and cooked food and has successfully developed a "earthy taste", other time-honored brands are not "vegetarian".

Bright Village is not the only one selling fresh meat moon cakes.

Taikang, which has set up a baking counter for local products all over the country, and Laodafang in the South District, which has just opened its store, are "away from home", but the price is set at "proud", and one fresh meat moon cake is sold in 6 yuan.

Changchun Food Store and Laodachang are "old lands", and the price of fresh meat moon cakes is the same as that of Guangming Village, so they sell one from 5 yuan.

Laodachang is also a "boiler pie", and there is a pan in the shop that is now for sale.

Do it now and sell it now

There are many people who like it.

Although the popularity is not as good as that of Guangming Village, there are people queuing in twos and threes from time to time at the counters shared by Liuxin Egg-yolk Crisp, Barbecued Crisp and Coconut Roll.

In contrast, Changchun treats fresh meat moon cakes more seriously and has set up a special counter.

Its fresh meat moon cakes are usually "oven pie", but near the Mid-Autumn Festival, the variety of traditional boiler baking has recently been added.

Changchun food store

Specially set up a fresh meat moon cake counter.

The poster emphasizes the use of Eisen meat.

Speaking of fresh meat moon cakes, Changchun sighed.

The so-called "thirty years in Hedong, thirty years in Hexi", once upon a time, fresh meat moon cakes in Changchun were the "king of popularity" in this street.

"Allah was originally artificial, baked with a pan of charcoal fire, and began to do it in 1997." Insiders in Changchun said, "There are about ten years in Guang Chen, and Allah has done a good job."

Changchun is now all year round.

Add "Boiler Edition" before Mid-Autumn Festival.

In this regard, insiders of Guangming Village also admit that fresh meat moon cakes in Changchun sold better than them at first.

As for how to catch up with it later, insiders in Guangming Village say:

"One year after the renovation (referring to Changchun), Allah began to overtake. In fact, we were ready before this, and the quality was quite tight. So I rushed out once I had the chance. "

In this regard, Changchun is noncommittal, just saying: "We are ancestors of fresh meat moon cakes." He also revealed that Guangming Village had learned from them in his early years.

I heard that the fresh meat moon cakes in Changchun are "ancestors", and Harbin Food Factory laughed.

An old mage who worked in Harbin Food Factory for many years told us: "We first taught Changchun fresh meat moon cakes."

The origin is this:

Harbin and Changchun belong to Shanghai Tobacco Group.

"Changchun was originally just a retail store. They want to diversify and be a’ front shop and back factory’-the workshop upstairs produces moon cakes and then sells them in the shop downstairs. "

Therefore, as a brother unit of the same group, Harbin is duty-bound to teach the skills of making moon cakes.

In Harbin, which started with Russian West Point, fresh meat moon cakes are actually well-founded. Because a few years ago, Gao Qiao Food Factory was merged into Harbin.

Back then, Gao Qiao Food Factory’s fresh meat moon cake was also a famous brand on Huaihai Road.

In 1983, it was reported in Wen Wei Po that Gao Qiao Food Factory on Huaihai Road insisted on supplying fresh meat, moon cakes and other special varieties, which were well received by consumers.

In Wen Wei Po in 1983.

There is even a saying that the predecessor of fresh meat moon cakes is Gao Qiao muffins.

Gao Qiao muffin is one of the four famous spots in the ancient town of Gao Qiao, which has a history of one hundred years. Among them, Gao Qiao muffins with fresh meat stuffing are crispy and juicy, which is said to have gradually evolved into fresh meat moon cakes.

Now that Changchun and Guangming Village are leading the way, the old master of Harbin admits: "The apprentice defeated the master."

In this regard, Harbin is also calm: "Their meat stuffing is wrapped on the spot and baked very fresh. Unlike our meat stuffing, it was delivered after being frozen in the factory on Quxi Road. "

"So we thought about it, and our focus is not on fresh meat moon cakes."

The "Big Three" on Huaihai Road have their own opinions about fresh meat moon cakes, which have been interpreted as a "Rashomon" story.

four

Looking at the whole country, Shanghai may be the city that loves fresh meat moon cakes most. Hungry take-away data show that last year, Shanghainese ate 53% of the country’s fresh moon cakes.

When did Shanghainese begin to like fresh meat moon cakes? It is probably impossible to test the age.

However, we can see from the database that as early as 1928, an advertisement for old Yuchang fresh meat moon cakes on Aiduoya Road (now Yan ‘an East Road) was published in Shenbao.

This advertisement in Shenbao, a bus stop at Sinan Road, Huaihai Middle Road, said

Lao Yu Chang de Xiao zhi fresh meat moon cake

"Choose the best ingredients, so it’s delicious."

Regarding the origin of fresh meat moon cakes, the version introduced by the real boss room is that in the past, there was a kind of fresh meat dumplings that was very popular in Soviet-style tea.

Its outer skin is brown and crispy, the middle layer is delicate and crisp, and the inner layer is fresh and firm meat stuffing.

Later, a master "opened his brain wide" and changed the shape and size of fresh meat dumplings, which became fresh meat moon cakes.

There are also many fans.

On September 14th, 1980, Liberation Daily reported that there were 147 units producing moon cakes in Shanghai catering industry that year, among which 127 households produced fresh meat moon cakes.

In Liberation Daily in 1980.

Report on Mid-Autumn Moon Cake

Two years later, Wen Wei Po reported that on the eve of Mid-Autumn Festival, nearly 200 restaurants in this city served fresh meat moon cakes. In order to meet the needs of consumers, the supply of fresh meat moon cakes this year increased by about 50% compared with the previous year.

The supply of stores and output both increased because "fresh moon cakes are crispy in skin, big in stuffing, fresh and bittern in meat, salty and sweet, and have a unique flavor. Generally, they are sold now, baked while cooking, and full of fragrance, which is very popular among consumers."

In 1989, Liberation Daily continued to report that "the sales of sweet moon cakes dropped sharply, but the sales of fresh moon cakes soared."

"Salty moon cakes are the most popular ones, so there are more than 70 shops selling fresh meat moon cakes on the streets of Shanghai this year, and even some fresh meat moon cakes made by big cake stalls are queued, which is in short supply."

In Liberation Daily in 1989

Report on Mid-Autumn Moon Cake

According to the report, fresh meat moon cakes are favored because the tastes of Shanghainese are changing.

"A customer who queued up in front of Yuelaifang Food Store in Putuo District told the reporter: Nowadays, moon cakes are like sugar cakes, which are too sweet and expensive. They are not as good as cheap and good meat moon cakes, which are fresh and fragrant."

By the way, Yue Laifang, who lives in the west of Shanghai, also has a name in the "History of Fresh Meat Mooncakes in Shanghai". Many people believe that fresh meat moon cakes were first sold by Yue Laifang.

It can be seen that over the years, Shanghai people’s preference for fresh meat moon cakes has been increasing day by day and has never been reduced.

If we say that the "love and hate" between Guangming Village, Changchun and Harbin on Huaihai Road around fresh meat moon cakes is a story of nearly twenty years.

Then, on Nanjing Road, another famous commercial street in Shanghai, the real old house has been famous for a long time.

Before the Mid-Autumn Festival in 2003

The queue of the real boss’s room is grand

/Shao Jianping photo

As early as 1982, it was reported in the newspaper that the fresh meat moon cakes in the real boss’s room won the first prize in the quality appraisal of moon cakes by catering companies in the city.

In 1986, Xinmin Evening News reported, "The fresh meat moon cakes produced by this store pay attention to the strict control of specifications and quality, and the minced meat is all lean-legged meat. Since its listing, the daily sales volume has reached about 3,000 kilograms. "

In Xinmin Evening News in 1986

A report on the real boss’s house

In 2005, the Jiang Shen Service Herald wrote: "Every year’s’ moon cake season’, there will be amazing all-weather’ long queues’ here, sometimes even winding more than 100 meters!"

However, on Nanjing Road, the real boss has a close competitor-Taikang.

Public comment

Netizens like the mooncakes of the two families.

Compare them.

In 2011, "Morning News" took stock of the "queuing index" of the time-honored fresh meat moon cakes in Shanghai. The two companies are comparable, and the queue time is about 6 hours.

A report in the Morning News in 2011

Inspected the time-honored brands.

"queuing index" of fresh meat moon cakes

What I want to tell the people who eat melons quietly here is that these two food stores with their own fans are actually "a family"-both belong to Taikang Food Co., Ltd.

Some people go to Huaihai Road and Nanjing Road to queue up to buy moon cakes every year, but in the eyes of citizens in the western district, the fresh meat moon cakes in the old house in the western district are the best ones.

The story of the real boss’s house and the old boss’s house in the west end of the country, which was taught by the same family in the early years, has been "eight" before, so we can’t press it here.

The fresh meat moon cakes of these two companies have always been equally famous, ranking almost the same.

We went through the newspaper pile again, and in 1982 and 1986, when the real boss room was reported, the boss room in the west side was also reported.

"At the entrance of Jing ‘an Temple’s’ Western District Old House’, customers often queue up to buy fresh meat moon cakes. An old uncle praised:’ the fresh meat moon cakes here are delicious and keep on selling all year round.’ ….. Near the Mid-Autumn Festival, the business of "the old house in the west side" is better. On September 7th, more than 14,700 fresh meat moon cakes were sold. "

-Xinmin Evening News, September 08, 1982, "The fragrance of cakes is accompanied by the fragrance of osmanthus"

Just like the real boss’s room.

The old house in the west side is also often there.

Appeared in reports about fresh meat moon cakes.

"The special fresh meat moon cakes produced by the old house in the west area of Jing ‘an Temple this year are among the best in the evaluation of the city tobacco and sugar company."

-Xinmin Evening News, September 12, 1986, "Fresh meat moon cakes here are welcomed by customers"

They all say "orange in the south and orange in the north". Last year, our old friend, folk photographer Shou Yousen, saw in Jing ‘an Temple that the fresh meat moon cakes in the old house in the West District were treated in line as usual.

Taikang, who had a long queue on Nanjing Road, opened the counter next to the old house in the west, but it was deserted. .

Seeing Taikang, which is very popular on Nanjing Road.

It’s cold next door to the old house in the west side

Shouyousen sent a circle of friends.

It seems that Shanghainese eat fresh meat moon cakes, which are not only delicious, but also famous and lively.

Opinions on the implementation of vaccine circulation and vaccination management

?
People’s governments at the local level and listed, people’s governments of counties (cities, districts), departments and institutions directly under the provincial government:

  In order to implement the Opinions of the General Office of the State Council on Further Strengthening the Management of Vaccine Circulation and Vaccination (Guo Ban Fa [2017] No.5), combined with the actual situation in our province, with the consent of the provincial people’s government, we hereby put forward the following implementation opinions.
  First, improve the vaccine management mechanism

  (a) improve the province’s immunization program vaccine adjustment mechanism. The Provincial Health and Family Planning Commission should improve the system of expert advisory committee on immunization planning, timely adjust the immunization planning policy of our province according to the national decision-making and deployment, and regularly carry out vaccine monitoring for diseases. After the demonstration by the expert advisory committee, the Provincial Department of Finance will propose suggestions on increasing the types of vaccines provided to citizens free of charge, which will be announced and implemented after being approved by the provincial people’s government and put on record by the National Health and Family Planning Commission. Encourage all localities to increase the types of vaccines provided free of charge to citizens in light of actual conditions.
  (two) improve the compensation mechanism for abnormal reaction of vaccination. Encourage the establishment of a mechanism to compensate the recipients of abnormal vaccination reactions through commercial insurance, and gradually establish a multi-level insurance compensation system including basic insurance and supplementary insurance to improve the compensation efficiency of abnormal vaccination reactions. Before the establishment of the compensation insurance mechanism for abnormal reaction of vaccination, compensation should be carried out according to the existing regulations.
  (three) to establish a joint meeting system between vaccine circulation and vaccination management departments. The Provincial Health and Family Planning Commission and the Food and Drug Administration, together with relevant departments, establish a joint meeting system between vaccine circulation and vaccination departments, clarify the division of responsibilities of each department, constantly improve the coordination mechanism, strengthen communication and cooperation in vaccine production, circulation, vaccination, vaccination certificate inspection, replanting and publicity, timely inform the progress of work, promote information sharing, coordinate with major emergencies, jointly study and solve outstanding problems, and form joint efforts.
  Two, strengthen the whole process management of vaccine production, circulation and use.

  (1) Promote independent research and development of vaccines and improve their quality. Support the research and development and industrialization of new vaccines in our province, especially multi-valent vaccines, through provincial science and technology plans (special projects, funds, etc.), major science and technology projects and other scientific research projects. Promote vaccine production enterprises to improve the quality management level and standardize production capacity, and continuously improve the quality of vaccine products. Actively promote the construction of vaccine research and development, production and clinical trial bases in our province, and promote the development of vaccine-related industries.
  (two) standardize the centralized procurement of vaccines. Incorporate vaccine procurement into the provincial third-party drug electronic trading platform, and implement centralized online procurement in accordance with the principles of openness, transparency, competition and fair trade. The Provincial Health and Family Planning Commission should further improve the centralized procurement plan for the second kind of vaccines in our province. Entry-exit inspection and quarantine departments should strengthen the management of entry-exit vaccination, and do a good job in the procurement, storage and use of vaccines required for entry-exit personnel in our province.
  (3) Strengthen the cold chain distribution management of vaccines. Provincial Food and Drug Administration should strengthen the inspection of cold chain storage and transportation conditions of storage and distribution enterprises. The Provincial Health and Family Planning Commission should take the lead in organizing the formulation of cold chain equipment standards for disease control and prevention institutions. Local health and family planning departments should regularly evaluate the cold chain facilities and equipment of disease control institutions and inoculation units in their respective jurisdictions to ensure that the cold chain equipment is in place according to standards and operates normally. All localities should take effective measures to ensure timely delivery of vaccines within their jurisdiction, especially in remote areas.
  (four) to strengthen the whole process of vaccine traceability management. The Provincial Food and Drug Administration shall, jointly with the Provincial Health and Family Planning Commission, strengthen the traceability management of the whole process of vaccine production, circulation and use. The Provincial Health and Family Planning Commission should speed up the embedding of the provincial vaccination information management system into the information management system of provincial primary medical and health institutions, and realize the docking with the relevant information systems of food and drug supervision departments and education departments. All vaccination units should implement vaccination information management.
  Third, standardize vaccination management

  (a) to strengthen the overall management of the second kind of vaccination. The provincial centers for disease control and prevention should promptly carry out the evaluation and selection of the second kind of vaccines and put forward the use items. Actively promote the second type of vaccine appointment vaccination service. County-level health and family planning departments should determine the vaccination units within their jurisdiction according to factors such as the service population and service scope, and announce them to the public. In principle, rural areas implement a centralized vaccination model with townships as the unit. Strictly regulate the service behavior of village-level vaccination units. The Provincial Development and Reform Commission should speed up the formulation of the charging standards for the second kind of vaccination service fees and vaccination consumables fees charged by vaccination units in our province. The problem of storage and transportation fees for the second kind of vaccines should be solved in a market-oriented way in the bidding and procurement of the second kind of vaccines.
  (two) to strengthen the standardization of vaccination units. Strengthen the standardization and informatization construction of public hospitals, community and township vaccination units. Further standardize the establishment of vaccination units, personnel qualifications, vaccination facilities, cold chain management, monitoring and handling of suspected abnormal reactions to vaccination, and vaccination notification, recording, reporting and publicity. The inoculation entity shall publicize the immunization procedures, vaccine varieties, inoculation methods, vaccine functions, contraindications, adverse reactions and precautions, the price of the second kind of vaccine, the charging standard of vaccination service, consultation and complaint telephone number and other matters in a prominent position in the inoculation site. Local health and family planning departments should implement dynamic management of vaccination units, strengthen technical training of vaccination professionals, complete grading evaluation of all vaccination clinics and full coverage of supervision of other vaccination units before the end of 2017, and organize spot checks on the standardized construction of vaccination units every year. Medical personnel who undertake vaccination duties and tasks in medical and health institutions should pass the vaccination professional training organized by the county-level health and family planning administrative department and pass the examination.
  (three) to strengthen the assessment of vaccination work. Take the results of vaccination assessment as an important basis for allocating subsidy funds for basic public health services. According to the provisions of the implementation of disease prevention and control personnel subsidies policy, scientific verification of disease prevention and control institutions total performance pay, the establishment of vaccination outpatient performance pay and vaccination outpatient grade, vaccination service linked to vaccination incentive mechanism.

Consumers encounter "toxic" rental housing experts: pollution should be reduced from the source

  Our reporter Wen Wen Intern Cheng Weijia

  The problem of excessive formaldehyde in rental houses has recently aroused social concern. Chain Home Group’s long-term rental apartment service provider "freely" announced that all the first-time rental houses in 9 cities across the country have been removed from the shelves since September 1, and will not be put on the shelves until the professional certification bodies have passed the inspection. This is also a response to many complaints about air quality problems in long-term rental houses.

  Why do long-term rental houses have excessive indoor formaldehyde? How to avoid indoor air pollution when decorating houses? The reporter conducted an interview a few days ago.

  Renting a house encounters "formaldehyde exceeding the standard"

  I thought the online news was far away from me, but I didn’t expect that in just one month, two students of the reporter both encountered air pollution problems in the process of renting a house.

  Xiao Guo, a graduate student from Shanghai who came to Beijing, just solved the problem of finding a job, but experienced a disturbing storm of excessive formaldehyde in renting a house.

  A few days after staying in the rented house, Xiao Guo felt a sore throat and headache, and his eyes were dry and even a little unclear. Xiao Guo bought a test paper online for testing, and found that formaldehyde in indoor air exceeded the standard by more than 12 times, even exceeding the extreme value that can be measured by test paper.

  Xiao Guo further investigated and found that the pollution source should be the newly changed furniture provided by the intermediary. In desperation, she had to find a rental agent, arguing that she hoped to replace the furniture and compensate for physical damage.

  However, the intermediary company refused to replace the furniture, claiming that it can withdraw the rent, but it is considered that the renter has breached the contract and needs to pay the corresponding liquidated damages. On the one hand, it is a health hazard, on the other hand, the house you rent can’t live, and you can’t defend your rights. You can’t find a house for a while when you change rooms. Guo is very embarrassed and can only stay at a friend’s house temporarily.

  Xiao Guo’s experience is not unique in big cities such as Beijing and Shanghai.

  Xiao Dong, another classmate of the reporter, works for a famous large Internet company in Beijing. In order to facilitate commuting, she chose to rent near the company and found a "free" rental house.

  Due to the tight housing of the "Free" platform, Xiao Dong quickly rented the house before he had time to look at it carefully. However, after checking in, I found that the smell in the room was very strong, and I would feel dizzy after sleeping for one night in the morning. After testing confirmed that the indoor air formaldehyde exceeded the standard, the "Free" platform provided free rent change. However, due to the shortage of housing near the company, there is no suitable house replacement for the time being, and Xiaodong can only continue to rent in a house with excessive formaldehyde.

  Now Xiao Dong has bought an air purifier in in addition to formaldehyde from his own pocket. "The effect is like that, and it is a peace of mind."

  Recently, the number of complaints about indoor air pollution in long-term rental houses such as "Free" has increased. In this regard, many tenants feel helpless and are in a dilemma.

  Lack of supervision and system makes it difficult to protect the rights of air pollution in long-term rental houses.

  Reducing the cost of decoration and shortening the time from the completion of decoration to the opening of rent make the indoor air pollution problems of long-term rental houses frequent.

  As a commercial operation, long-term rental apartments and long-term rental houses must consider their costs and profits. According to industry sources, the decoration standard of ordinary long-term rental apartments is not too high, and in some second-tier cities, it is often less than 500 yuan/square meter. And the average family decoration cost is at least 700 yuan ~800 yuan per square meter. In addition, the decoration time is as short as possible, often controlled within one month. In the mode of "low" and "fast", the indoor air quality of houses is not optimistic.

  Ordinary home improvement rooms will be ventilated and "aired" for 3 to 6 months after renovation, so that harmful gases such as indoor formaldehyde can be fully volatilized. However, in order to pursue economic benefits, many apartment intermediaries rent out their houses immediately after renovation. Even an apartment manager said, "In order to control costs, renovated houses are usually placed for up to 3 days, and then listed for rent."

  At the cusp of public opinion unanimously demanding that the rental platform take measures, "Freedom" promised in the announcement that tenants who stayed in "Freedom" for the first time after June 1, 2018 can apply for free air quality testing if they have doubts about indoor air quality. If there is a problem that the air quality of the house exceeds the standard, one of three options can be provided, including unconditional rent withdrawal and rent change; Provide free air quality control, and check in after passing the inspection; Or provide a brand air purifier for free use for 90 days.

  The effect of "freely" solving problems remains to be seen. However, there are still no relevant measures for more long-term rental intermediary platforms.

  For most tenants, they are in the downstream of housing lease and are vulnerable groups; More importantly, in the current laws and regulations, there are no clear constraints and regulations on the indoor air quality of rented houses, which undoubtedly increases the difficulty of tenants’ rights protection.

  At present, China’s indoor air testing is based on the Indoor Air Quality Standard promulgated and implemented in 2002 and the Code for Indoor Environmental Pollution Control of Civil Construction Projects implemented in 2013. In the Indoor Air Quality Standard, the indoor formaldehyde standard is 0.1 mg/m3 (one-hour average), but this standard is not mandatory.

  In some cities, there is no design to restrict the air quality of rental housing decoration environment, and the formaldehyde treatment of some intermediary companies is still blank.

  Many tenants believe that simply returning the room unconditionally cannot finally solve the problem. "My health has been hurt, the time and energy spent in the coordination process, and the mental anxiety suffered by the unreasonable treatment of the rental platform. Who will bear these?"

  "If the formaldehyde in the rental house exceeds the standard, the intermediary company or landlord should bear the medical expenses or other financial compensation for the tenant." Xiao Guo told reporters like this.

  Suspected that the formaldehyde in rented houses exceeded the standard.

  Evidence should be obtained in time and a third party should be invited to identify it.

  "In order to maximize the benefits, some housing agencies rent out houses that have just been renovated for a few days, which is irresponsible for the tenants’ right to health." Han Xiao, a Beijing Kangda law firm, said in an interview with the media that if the court finds that there is a causal relationship between the tenant’s illness and the decoration and the house, according to Article 2 of China’s Tort Liability Law, the house decoration and lessor should bear the corresponding civil liability for compensation. At the same time, he introduced that at present, China’s housing rental disputes are mainly based on the Tort Liability Law, the Contract Law and the Judicial Interpretation of Personal Injury Compensation.

  Whether the diseases suffered by residents are caused by excessive formaldehyde, if it is difficult to get the results in medical appraisal, the renter’s appeal may not be supported by the court in the end. Han Xiao reminded the public that if tenants feel unwell or suspect that formaldehyde exceeds the standard, they should immediately obtain relevant evidence, hire a third-party professional organization to conduct appraisal, move out immediately after doing the corresponding appraisal, ensure their personal safety to the maximum extent, and hire lawyers to take corresponding rights protection channels.

  However, he also admitted that even so, after looking for a professional appraisal agency to make an appraisal, some parties still could not directly point the cause of the disease to excessive formaldehyde.

  Luo Laiheng, a doctor in Nanchang Second Hospital, also agrees with Han Xiao’s statement. He said that the causes of the disease are various and not necessarily directly related to the decoration, so it is difficult to determine the specific causal relationship in medical appraisal. Yan Yuejin, research director of the think tank center of Shanghai Yiju Real Estate Research Institute, suggested that in case of suspected formaldehyde exceeding the standard, consumers should not only actively collect evidence, but also promptly complain to operating enterprises and relevant regulatory authorities.

  — — Expert advice

  Reduce pollution from the source, and the materials are environmentally friendly and ventilated.

  At present, the housing supply in the rental market is tight, and tenants generally have a headache if they encounter problems such as excessive formaldehyde. After all, it is related to human health and cannot be sloppy. However, it is difficult to prevent indoor air pollution. After the discovery, due to the cost of living, economic cost and time cost, there is limited room for choice in the seller’s market.

  In addition, because it is difficult to bear the high cost of asking a professional formaldehyde testing team to collect evidence, the harm of formaldehyde to the body can not be shown in a short time. It is easy for intermediary companies to avoid responsibility, and it is difficult for tenants to obtain compensation. Everyone can only choose not to do it or compromise.

  Practice has proved that it is difficult to protect the health rights and interests of renters by relying solely on the independent adjustment of both parties, and it is also not conducive to the rights protection of consumer disputes. There is still a lack of clear rules for solving the problem of rent withdrawal claims caused by excessive formaldehyde.

  "In the United States, the law clearly stipulates that rented houses must be rented after half a year of renovation." Peng Yingdeng, a researcher at the National Urban Environmental Pollution Control Technology Research Center, told reporters.

  In addition to laws and regulations, in order to prevent indoor pollution, the United States and other developed countries have also taken some supporting measures. Peng Yingdeng told reporters that in many developed countries, furniture and building materials are required to use more environmentally friendly materials. "Most foreign furniture and building materials use phenolic resin, which contains only a small amount of formaldehyde and is basically negligible."

  Peng Yingdeng said that the cost of phenolic resin is high, and many domestic enterprises choose to use urea-formaldehyde resin with much lower price in order to save costs, while urea-formaldehyde resin contains high formaldehyde. "The furniture in the Olympic Village of Beijing Olympic Games uses phenolic resin, and there is no indoor pollution problem."

  Peng Yingdeng suggested that the state should reduce indoor formaldehyde pollution by controlling the raw materials of furniture and building materials, and encourage or support enterprises to use more environmentally friendly products. Cheap building materials bring temporary cost reduction and enterprise profit increase, but in the long run, the damage to human health can’t be measured by money.

  Experts in the industry also suggested that formaldehyde is a "self-contained component" in many building decoration materials. Even if you carefully select and use high-quality and environmentally-friendly decoration materials, it is difficult to completely avoid its invasion. Therefore, it is necessary to maintain ventilation for a period of time after the renovation of new houses to ensure safety.

Children’s colds and flu are treated differently.

In daily life, parents tend to confuse children’s common cold with influenza. In fact, there are great differences between them in pathogen, infectivity, symptoms and medication. Parents should carefully distinguish whether their children are suffering from the common cold or the flu, and take medicine according to the symptoms.

Common cold

The common cold is mainly caused by viruses, and children will have symptoms such as stuffy nose, runny nose, sneezing, coughing and fever. The common cold is often a mild self-limiting disease, which can be gradually relieved without taking medicine.

In infants and young children, the symptoms of the common cold are usually more serious on the second to third day, and gradually relieved on the tenth to fourteenth day. A few children may cough for 3-4 weeks. Older children and adolescents generally have cold symptoms gradually subsided in 5-7 days, and children with basic lung diseases may last longer.

There is no specific medicine for the common cold. Taking medicine is mainly to relieve symptoms and make children feel less uncomfortable. The commonly used therapeutic drugs for relieving cold symptoms are shown in Table 1.

It should be noted that children should not be given cold medicine containing codeine. Although codeine has a strong antitussive effect, long-term use may cause physiological dependence and addiction. National Medical Products Administration’s announcement on revising the instructions for cold medicines containing codeine clearly points out that it is forbidden for children under 18 to use cold medicines containing codeine. Then, how to relieve the mild cold symptoms of children?

When the body temperature caused by fever is above 38.2℃, children over 2 months old can use acetaminophen to reduce fever, and children over 6 months old can use acetaminophen or ibuprofen to reduce fever. For the symptoms of nasal congestion and runny nose, it is suggested to relieve the symptoms by dripping salt water into the nose, spraying nose, nasal irrigation, etc. Children under 6 years old are generally not recommended to use drugs (such as compound cold medicine) to relieve the nasal symptoms, because these symptoms will generally gradually relieve themselves, and adverse reactions may occur when using drugs. If you have a cold accompanied by cough, you can replenish water appropriately, which will help to dilute sputum and relieve respiratory mucosa. Children over 1 year old with common cold can take honey or honey water to relieve their cough. Honey has a mild cough relieving effect on night cough. It should be noted that children under 1 year old should not take honey, because it will increase the risk of botulinum poisoning.

Parents need to pay special attention to that children need to seek medical attention as soon as possible in the following situations: infants less than 3 months old have symptoms such as fever and cough; After taking antipyretics, the fever still persists or persists for 3 days; Persistent nasal symptoms, such as stuffy nose, runny nose, sneezing, etc., have lasted for more than the course or degree of the common cold; Abnormal conditions such as dyspnea, confusion and ear pain occur.

So, how to prevent children from catching a cold? The most important thing to prevent colds is to wash your hands frequently. It is best to use running water when washing your hands, and tell your child to rub it with hand sanitizer or soap for at least 20 seconds. In addition, we should pay attention to indoor ventilation, take children to crowded public places less, and try to wear masks when going out. If parents catch a cold, they should be isolated and reduce contact with their children. Pay attention to the combination of meat and vegetables in diet, ensure nutrition, take children to exercise more and ensure enough sleep time to enhance their physique and improve their immunity.

Common medication problems of common cold

Q: Can antipyretics and compound cold medicines be taken together?

A: no. Compound cold medicine usually contains antipyretic ingredients, which can easily lead to repeated medication and toxic and side effects when taken together with antipyretics. It is best for parents to choose a single ingredient medicine for their children. If you use a compound cold medicine, you must read the instructions carefully before using it, especially the ingredients, to know whether there are repeated drugs.

Q: Do Chinese patent medicines have any side effects?

A: Chinese patent medicines also have side effects. Although the adverse reactions written in the instructions of many Chinese patent medicines are unclear, this does not mean that they have no adverse reactions, and Chinese patent medicines are not necessarily safer than western medicines.

Q: Do children need antibiotics for their common cold?

A: no need. Common cold is caused by virus infection, and antibacterial drugs are mainly aimed at bacterial infection. The use of antibacterial drugs is not only ineffective for common cold, but also may cause bacterial resistance. Therefore, the common cold does not need antibiotics, unless the doctor clearly diagnosed bacterial infection or secondary bacterial infection.

Q: Can children take oseltamivir for a common cold?

A: no. The common cold is mainly caused by rhinovirus and coronavirus, while oseltamivir is aimed at influenza viruses, including influenza A and influenza B viruses, so oseltamivir is not symptomatic for treating common cold.

flu

Influenza is an acute respiratory infectious disease caused by influenza virus, which can be divided into four types: A, B, C and D. The most common type of influenza is seasonal influenza, which occurs in autumn and winter and is mainly caused by influenza A and B viruses.

Children’s influenza often starts suddenly, the main symptom is fever, and the highest body temperature can reach 39~40℃, often accompanied by chills and chills. Children will also have headaches, muscle aches, fatigue, loss of appetite and other manifestations. Cough, sore throat, runny nose and stuffy nose may also occur, and a small number may have digestive tract symptoms, such as nausea, vomiting and diarrhea. The symptoms of influenza in infants and young children are often not as typical as those in children, and may only be fever and cough. Newborn influenza is relatively rare, but complications often occur, such as pneumonia and dyspnea.

Mild influenza is often similar to the common cold, but its fever and systemic symptoms are more obvious. Severe children will have viral pneumonia, secondary bacterial pneumonia, acute respiratory distress syndrome, shock, disseminated intravascular coagulation, cardiovascular and nervous system and other extrapulmonary manifestations and various complications.

Influenza patients and recessive infected people are the main sources of seasonal influenza infection, mainly through droplets of respiratory secretions, but also through direct or indirect contact with oral cavity, nasal cavity, eyes and other mucosa. Influenza virus is easy to produce new mutant strains, so it can spread widely among people, causing repeated infections and diseases. Therefore, we must pay attention to it and do our best to prevent it.

Different from the common cold, influenza has a "nemesis", that is, neuraminidase inhibitors. At present, the drugs listed in China include oseltamivir, zanamivir and palamivir. Among them, oseltamivir is the most widely used anti-influenza drug for adults and children at present, and its best administration time is within 48 hours after the onset of flu symptoms, and it is also effective after 96 hours after the onset of flu symptoms. Specific therapeutic and preventive doses can be found in Table 2. Although vaccination is the best way to prevent influenza virus infection, oseltamivir can be recommended for people who cannot be prevented by vaccine and the following key children in the outbreak of influenza.

The recommended drug prevention population includes: high-risk children who cannot be vaccinated with influenza vaccine, or children with immune abnormalities who do not respond to the vaccine; High-risk children within 2 weeks of vaccination; Family members or caregivers who are in close contact with non-immunized high-risk children or infants younger than 24 months; In order to control the outbreak of influenza, it is used in children who have not been immunized or in children’s gathering places (such as kindergartens); Prevention after exposure of family members; Prevention of patients with high risk of influenza complications and close contact with influenza.

Vaccination against influenza can significantly reduce the probability of influenza in children and the risk of serious complications. Therefore, parents are advised to take their children to get the flu vaccine in time every year. Generally, it is planted indirectly from September to December every year, and it is best to complete immunization before the end of October. Children aged 9 and over are advised to take one dose in one flu season. For children aged 6 months to 8 years, it is recommended to vaccinate two doses for the first time, with an interval of one month. But not all children are suitable for vaccination, and infants less than 6 months old or children who are allergic to any component of the vaccine are not suitable for vaccination. In addition, if the child suffers from mild to moderate acute diseases, it is recommended to vaccinate after the symptoms subside.

When the child has the following situations, he should pay attention to seek medical attention in time: dyspnea or shortness of breath, which can not be relieved after cleaning the nasal cavity; Crying low, crying less, not having good eye contact with parents, poor spirit and listlessness; Drink less water, or there are signs of dehydration, such as no tears when crying, decreased urine output (dry diapers), dry mucous membranes such as lips, tongue and eyes, and skin like dough, which cannot be quickly recovered after gently pinching the skin; Severe or persistent vomiting; Poor appetite, significantly reduced eating; Persistent fever, with or without convulsions; Fever with rash.

Common drug use problems of influenza

Q: Can infants under 1 year old take oseltamivir granules?

A: Although the minimum age of the population suitable for oseltamivir granules is 1 year old, the US Food and Drug Administration has approved that oseltamivir can be used for infants over 2 weeks old. The British Ministry of Public Health guidelines also suggest that infants under 1 year old can use it. China’s "Expert Consensus on Diagnosis and Treatment of Children’s Influenza (2015 Edition)" puts forward that oseltamivir can be used for influenza treatment in children of all ages and influenza prevention in children over 3 months old. According to the above evidence, infants younger than one year old can take oseltamivir granules, but it is an over-the-counter drug in China at present.

Q: The child’s condition has improved after taking the medicine for 3 days. Can he stop taking the medicine?

A: Due to individual differences, some children may feel better after two or three days of medication, but they are not sure whether their illness will recur. It is suggested that they should take medication according to the course of treatment for five days.

Q: Can oseltamivir take the place of influenza vaccine to prevent influenza?

A: Drug prevention is generally only used as an emergency temporary preventive measure and cannot replace vaccine prevention. Vaccination against influenza is the first choice to prevent influenza.

Q: Can I treat the flu with antibacterial drugs?

A: no. Antibacterials only kill or inhibit bacteria, but have no effect on influenza virus.
