Upholding Party leadership and strengthening Party building are the "roots" and "souls" of state-owned enterprises. Zhuhai Communications Group Co., Ltd. is a wholly state-owned enterprise under the State-owned Assets Supervision and Administration Commission of Zhuhai City. The Party Committee of Zhuhai Communications Group Co., Ltd. (hereinafter referred to as "Zhuhai Communications Group") resolutely puts strengthening the party’s leadership into the overall strategic deployment of the enterprise, insists on the deep integration and integration of party building work with production and operation, and focuses on the main business of "helping Zhuhai to build a transportation network with internal connection and external expansion and efficient connection" around the general direction of "high-quality party building leading high-quality engineering construction". With the management concept of "three types and one integration" (leading, strict management, service-oriented and information-oriented), we spare no effort to insert party flag into the front line of the construction site, inject the red gene into the project construction, and fully roll out the demonstration of "red construction site", effectively transforming the political advantage of the party into the driving force for striving for quality engineering.

Party Committee of Zhuhai Communications Group won the title of "Advanced Grassroots Party Organization in Guangdong Province" in 2021.

　　Since its establishment, Zhuhai Transportation Group has undertaken more than 80 transportation projects, with a total investment of more than 80 billion yuan, with a total highway investment of about 49.236 billion yuan and a mileage of 381.4 kilometers. It has won a first prize for management innovation achievements of state-owned enterprises, a national high-quality project award, a highway transportation high-quality project award, four "National Municipal Jinbei Demonstration Project" awards and 103 provincial and ministerial awards. In 2021, the Party Committee of Zhuhai Communications Group won the honorary title of "Guangdong Advanced Grassroots Party Organization" and was the only municipal state-owned enterprise in Zhuhai to win this honor; Zhuhai Tunnel Project, Hegang Expressway Project, Xianghai Bridge Project (including feeder projects) and Jinhai Highway Bridge Project were awarded the title of "Red Site" demonstration project in Zhuhai in 2021, and the title of "Red Site" demonstration project for highway and waterway construction in Zhuhai in 2021 and 2022 respectively.

　　(A) strictly regulate the construction of grass-roots organizations, and vigorously inject "red genes"

　　The first is to select the best and strengthen the "first-line command". The Party Committee of Zhuhai Communications Group has fully summarized and absorbed the advanced practices and good experiences of party building and joint construction in construction projects, and comprehensively rolled out the creation of "red construction sites" in construction projects focusing on Zhuhai Tunnel, Hegang Expressway, Xianghai Bridge and Jinhai Highway Bridge, strictly implemented the "five haves and six haves" creation standards, and assembled construction, construction, supervision, survey and design units to establish party building and joint construction party branches. The general manager, director and chief engineer of each unit shall serve as the secretary and member of the Party branch of the United Party, implement "one post and two responsibilities", build a party building and co-construction mechanism that helps each other, promotes each other, shares resources and improves together, and effectively extend the tentacles of managing the party to the forefront of project construction.

　　The second is to build a "red gas station". The joint construction party branches insist on combining the position construction with the actual project construction, and have built high-standard hardware facilities such as party member activity room, party history study and education base, project workshop, cultural corridor, party-mass post station, VR safety experience hall, etc. at the project site, and effectively integrate the project production, quality, safety and progress into the political life and organizational life of the party by using regular meetings and project workshops according to local conditions, making party member education practical, effective and effective.

Construction of "Red Site" Positions of Joint Construction Party Branches

　　(B) in-depth education in party member, effectively lighting the "red engine."

　　First, strengthen political construction and build a solid ideological foundation. Guided by the party’s political construction, the joint party branches carry out in-depth study and education on party history in the first line of the project, carry out centralized study by making full use of "three meetings and one lesson", innovatively holding "lecture hall on party history" and "night party class", organize theme party day activities such as raising the national flag to sing the national anthem, watching red movies, visiting revolutionary sites and visiting party history exhibition halls, build "red promenade" and party history study and education bases in the project site, and guide party member from the first line.

　　The second is to serve the people and practice the initial mission. The joint construction party branches always take solving the people’s urgent difficulties and worries as their starting point and foothold, and take measures such as party member cadres’ first-line supervision, reversing the construction period plan, increasing resource input, organizing labor competitions, regular strict assessment and timely adjustment and rectification to promote the two key livelihood projects of Zhuhai SASAC, which have achieved the set goals with high quality and efficiency, greatly facilitating citizens’ travel. Earnestly serving the people, solving problems for front-line personnel, co-building with community party organizations along the project site, and actively participating in community volunteer service activities have narrowed the distance with the resident people and created a harmonious construction atmosphere.

　　The third is to deepen discipline construction and build a clean government defense line. Zhuhai Communications Group has undertaken major projects in Zhuhai, and it is particularly important to control the risk of clean government. All the joint party branches tamped with integrity prevention and control in an all-round and high-intensity way, and carried out activities such as party secretary’s lectures on integrity, knowledge contest on party rules and discipline, watching integrity education films, reminding people of integrity talks, and supervising integrity practitioners, which achieved publicity and education to the construction site, anti-corrosion responsibility to the post, integrity and self-discipline to ideas, and achieved two excellent "quality project" and "integrity project"; Combining the key links of the transportation industry, we have improved nearly 30 systems, such as the implementation rules of honesty and self-discipline, bidding management methods, contract management methods and design change management methods, and built a "firewall" of honesty; Implement special prevention and control in key areas and key links, and strengthen fund management in circulation links such as bidding, quality control, project payment, acceptance and settlement, and project change.

The joint party branches carry out party member education.

　　(C) vigorously promote the integration and mutual promotion of Party building and engineering construction, and fully stimulate the "red kinetic energy."

　　First, pay close attention to safety production. All joint construction party branches always put the implementation of safety in production in a prominent position, strictly implement the safety inspection plan, do a thorough investigation, rectification and routine inspection, and carry out project workshops, "Monday Safety Learning Day" activities, team "six small" construction, "May 1" test and detection skills competition, "pre-class meeting" competition, labor competition, "red armband" inspection and other forms.

　　The second is to focus on technological innovation. The joint construction party branches actively carry out the management concept of "three types and one integration" of Zhuhai Communications Group, put quality engineering in a prominent position, comprehensively promote the action of creating national excellence, and put six management innovations in the whole process of project implementation, including the access system for raw materials and temporary facilities, on-site "7S" standard management, dynamic first article acceptance system, process inspection and image retention system, BIM information management and safety information management platform, so as to comprehensively improve the quality of project construction. Zhuhai tunnel project strictly controls the access of raw materials and process supervision, and implements the first sample project acceptance system for key working procedures and parts; Hegang Expressway project combines the "red construction site" with the special action of project quality improvement and efficiency improvement, forming 57 technical points of green project creation and 23 technical demonstration highlights in 10 categories; Xianghai Bridge Project actively promotes the application and innovation of new technologies, implements classified management and hierarchical control of construction schemes, strictly implements expert argumentation and review of major schemes, and specially controls the special acceptance of working procedures; Jinhai Highway Bridge project vigorously promotes advanced and reliable construction technology and carries out technological innovation, such as using drip irrigation+one cloth and one film or film winding and spraying to maintain concrete members, which effectively ensures the engineering quality.

The joint party branches lead the quality engineering construction with the mode of "Party Building +N"

　　Effect of reform

　　First, the battle fortress was effectively built. The Party branch of each league effectively unites all the participating units, vigorously promotes the "Party Building +N" working mode, promotes the combination of party building work with project research and technical excellence, and effectively builds the battle fortress of the party branch in the front line of the construction site, providing a strong organizational guarantee for the project construction and a joint effort to overcome difficulties. Especially in the prevention and control of epidemic situation in Zhuhai in early 2022, the joint party branches went to the front line of community war and epidemic, while paying close attention to production and construction, which fully demonstrated the responsibility and responsibility of state-owned enterprises.

　　Second, the vanguard model is effectively highlighted. The joint party branches actively set up a pioneer model platform in party member, divided the responsibility areas in party member, set up a safety and quality supervision post in party member, a volunteer service team in party member, and a technical research team in party member, and set up party member vanguard teams to fight epidemic, rescue, create excellence, coordinate and guarantee, and tackle key technical problems, so as to promote party member to always show its identity, commitment and performance in key areas and important links. From July to September, 2021, party member, the Party branch of Hegang Expressway Project, actively played the vanguard and exemplary role and the spirit of "building an iron army", took the lead in grabbing progress and tackling difficulties, and promoted the trial operation of the first phase of Hegang Expressway more than three months ahead of schedule, effectively alleviating the east-west traffic pressure in Zhuhai during the 13th China International Aviation and Aerospace Expo.

Zhuhai Hegang Expressway Phase I Project

　　Third, the progress and quality of the project construction are effectively ensured. The comprehensive establishment of the "red construction site" has enabled all the party organizations of the participating units to work in the same direction for the same goal, effectively improving the rigid contractual relationship between Party A and Party B, creating a good atmosphere of equality, interaction and mutual assistance, and greatly enhancing the promotion and effectiveness of project construction. By the end of November, 2022, Zhuhai Communications Group had completed more than 50 key projects, including Honghe Bridge, Jinqin Express Line, Xianghai Bridge branch project Meihua Interchange to Beizao Interchange, Hegang Expressway Jiangzhu Expressway to Airport East Road, which was officially opened to traffic on December 15, 2020, Hegang Expressway from Airport East Road to Airport Expressway, which was opened to traffic at the end of September, 2021, and Xianghai Bridge on November 6, 2022. By the end of October 2022, Hegang Expressway had completed an annual investment of 919 million yuan, accounting for 83.52% of the annual investment plan; The accumulated investment is 7.668 billion yuan, accounting for 89.42% of the total investment. The second phase of Hegang Expressway is scheduled to be completed by the end of 2022 and opened to traffic in the first half of 2023. Jinhai Highway Bridge completed an annual investment of 758 million yuan, accounting for 86.14% of the annual investment plan; The accumulated investment is 4.747 billion yuan, accounting for 74.84% of the estimated investment. The first phase of the project is planned to be completed and opened to traffic in the second half of 2023. Zhuhai Tunnel completed an annual investment of 515 million yuan, accounting for 83.6% of the annual investment plan; The accumulated investment was 1.1 billion yuan,It accounts for 24.8% of the approved budget, and the project is expected to be completed and opened to traffic in 2024.

　　Next, the Party Committee of Zhuhai Communications Group will continue to adhere to the guidance of Socialism with Chinese characteristics Thought of the Supreme Leader in the New Era, thoroughly study and implement the spirit of the 20th Party Congress, consolidate and expand the grass-roots party building working mechanism that is consistent with the development goal of the main business, match the production mode and coordinate the management mode, fully activate the kinetic energy of "red construction site" creation, promote institutionalized implementation, standardized management and quality improvement, realize high-quality project construction led by high-quality party building, and contribute to Zhuhai’s high-quality construction of Socialism with Chinese characteristics modern international special economic zone in the new era.

In dry and cold climate, the defense function of human respiratory tract is easy to decrease, so every winter is the season of high incidence of respiratory tract infections. This year’s situation is a bit special. Although the common respiratory pathogens are popular in previous years, they can’t hold back and launch an offensive, making many children and even adults recruited.

Judging from the current situation, mycoplasma pneumoniae, influenza virus, respiratory syncytial virus and adenovirus are the main causes of respiratory infection in children this year. In view of these pathogens, we asked Fu Peipei, the pediatric attending physician of Beijing Friendship Hospital, to sort out their respective infection characteristics, clinical manifestations, treatment methods and preventive suggestions, hoping to help everyone spend the epidemic peak of respiratory infection more effectively and smoothly.

Mycoplasma pneumoniae

Mycoplasma pneumoniae is a pathogen between bacteria and viruses, and children are generally susceptible. Pneumonia caused by this pathogen is common in preschool and school-age children.

In Beijing, the previous epidemic season of mycoplasma pneumoniae was winter, and most of them were mild. Compared with previous years, the epidemic time of Mycoplasma pneumoniae was earlier this year, and it spread widely, and the cases of severe pneumonia and refractory pneumonia increased significantly. However, from the overall situation of children infected with mycoplasma pneumoniae, upper respiratory tract infection is still the majority.

symptom

After being infected with mycoplasma pneumoniae, the main symptom is fever or cough. Children with mild illness may have mild fever or cough, and some of them will get better on their own. When pneumonia develops, children often show moderate or high fever, severe cough, and even spasmodic cough like pertussis and prolonged cough. More serious severe mycoplasma pneumonia usually occurs in the course of about 1 week, and children may have shortness of breath or dyspnea.

suggestion

Persistent high fever > 3 days or fever > 7 days, or dyspnea, chest pain, poor spirit, headache, convulsions, frequent vomiting, etc., it is recommended to seek medical advice in time.

treat

For mycoplasma pneumoniae infection, the first choice drugs are still macrolides, including azithromycin, erythromycin and clarithromycin. For drug-resistant mycoplasma infection, children over 8 years old can choose tetracycline drugs, such as doxycycline and minocycline.

Children with mild pneumonia need not be hospitalized, but can be observed and treated at home; Children with severe pneumonia are advised to be hospitalized in time. Parents should not give their children antibiotics by themselves, but must choose a treatment plan suitable for their children’s condition under the guidance of a doctor.

prevent

It should be noted that Mycoplasma pneumoniae is mainly transmitted through respiratory droplets, and the incubation period is 1-3 weeks. At present, there is no vaccine to prevent Mycoplasma pneumoniae. Developing good hygiene habits, such as wearing masks and washing hands frequently, is the main means to avoid infection.

Influenza virus

Influenza, referred to as influenza for short, is an acute respiratory infectious disease caused by influenza virus. Influenza A and B are seasonal epidemic every year, and generally all parts of China have entered the influenza epidemic season since October.

According to the data released by the Beijing Municipal Center for Disease Control and Prevention, the number of influenza cases in Beijing has increased rapidly recently, and it is prevalent with many other pathogens. For influenza virus, people are generally susceptible, and children under 5 years old and elderly people over 65 years old are prone to serious complications, so they are also called high-risk groups of influenza.

symptom

After being infected with influenza virus, fever, headache, myalgia and general malaise are the main manifestations, and the body temperature can be as high as 39℃-40℃. Some children have cough, but it is not severe, and it can also be accompanied by nasal congestion, runny nose and conjunctival congestion. Children infected with B-stream may have digestive tract symptoms such as vomiting, abdominal pain and diarrhea. When the newborn is infected with influenza, it can be manifested as drowsiness, refusal to milk, apnea and so on.

Some mild children can get better on their own, and their fever gradually decreases after 3-4 days of onset, and their systemic symptoms get better, but it may take a long time for cough and physical recovery. Severe children may have serious complications such as pneumonia, myositis, acute necrotizing encephalopathy and septic shock.

suggestion

For children with persistent high fever for more than 3 days, or with symptoms such as dyspnea, poor spirit, chest pain and frequent vomiting, it is recommended to seek medical advice in time.

treat

The main treatment of influenza is antiviral therapy, and three drugs are often used in clinic: 1. Neuraminidase inhibitors, such as oseltamivir, zanamivir, palamivir, etc., can prevent the virus from being released from host cells and have the effect of resisting influenza A and B; 2. Balofloxacin can inhibit the initiation of mRNA synthesis and prevent virus proliferation. It is effective for both influenza A and influenza B, and is suitable for children aged ≥5 years and weighing ≥20kg. 3. Adamantane drugs, which act on M2 protein of influenza A virus, can prevent the virus from replicating efficiently, but have no effect on influenza B virus. However, the strains of influenza A virus spread since 2009 are generally resistant to adamantane drugs and are not recommended.

prevent

The incubation period of influenza virus is 1-7 days, usually 2-4 days. Vaccination against influenza is the most effective means to prevent influenza, which can reduce the incidence of influenza and the risk of serious complications. High-risk groups with a history of contact with influenza virus can take drugs within 48 hours, such as taking oseltamivir or zanamivir (the dose is the same as the therapeutic dose, once a day for 7 days).

Respiratory syncytial virus

Respiratory syncytial virus (RSV) is the most important virus pathogen causing acute lower respiratory tract infection in children under 5 years old worldwide. In addition, it is also an important pathogen of acute lower respiratory tract infection in the elderly and immunocompromised people. Respiratory syncytial virus can also cause upper respiratory tract infections such as rhinitis and colds in older children and adults.

symptom

The clinical manifestations of children infected with respiratory syncytial virus vary greatly. Children’s early respiratory syncytial virus infection is mostly confined to the upper respiratory tract, showing symptoms such as fever, stuffy nose, runny nose and cough. It can also develop into pneumonia, which is common in infants and children under 2 years old. It is characterized by cough, excessive phlegm, wheezing, dyspnea and feeding difficulties.

suggestion

Infants and young children are infected with respiratory syncytial virus, so it is suggested to check the etiology in time, and pay attention to the breathing situation of children. If they have difficulty breathing, wheezing and poor mental health, they should seek medical advice in time.

treat

At present, there is no specific drug for respiratory syncytial virus infection, and people with normal immune function are generally self-limited after infection, and do not need special treatment, which will rarely cause serious complications. The main treatment principle is symptomatic support treatment to relieve the symptoms of cough, wheezing and dyspnea in children. For children with lower respiratory tract infection, interferon antiviral therapy can be tried.

prevent

The incubation period of respiratory syncytial virus is 2-8 days, usually 4-6 days. At present, there is no respiratory syncytial virus vaccine for children. Palizumab is a specific antibody against respiratory syncytial virus, which can be used to prevent infection in high-risk groups, but it has not been introduced into domestic clinical application. Therefore, developing good hygiene habits is still the main means to avoid infection at present.

adenovirus

Adenovirus is a common virus of respiratory tract infection in children, and it is also one of the more serious types of community-acquired pneumonia in children. Acute infectious diseases caused by adenovirus easily invade respiratory tract and digestive tract mucosa, conjunctiva, urinary tract and lymph nodes, mainly manifested as acute upper respiratory tract infection, followed by eye and gastrointestinal tract infection. People are generally susceptible, especially children, and infants are prone to adenovirus pneumonia, with serious illness and high mortality.

symptom

Children infected with adenovirus often show high fever, and most of them have high fever above 39℃ at the beginning of the disease, which may be accompanied by cough and wheezing (wheezing is usually seen in infants aged 6 months to 2 years). Mild children’s body temperature can return to normal in about 7-11 days, and other symptoms will disappear; Severe children with high fever can last for 2-4 weeks, and dyspnea usually begins 3-5 days after illness, accompanied by symptoms of systemic poisoning, listlessness or irritability, irritability and even convulsions. Some children have diarrhea, vomiting, and even severe abdominal distension. A few children have conjunctival congestion and tonsil secretion.

suggestion

For children with adenovirus infection, besides observing their body temperature changes, they also need to observe their breathing conditions. If they have difficulty breathing, wheezing, poor spirits and frequent vomiting, they should seek medical advice in time.

treat

Similar to the situation of respiratory syncytial virus, there is no specific drug for adenovirus infection, and people with normal immune function are self-limited after being infected with adenovirus and do not need special treatment. In most cases, the treatment principle of adenovirus is symptomatic supportive treatment, mainly to relieve children’s discomfort such as high fever and cough. Children with serious complications need to be hospitalized in time.

prevent

The incubation period of adenovirus is generally 2-21 days, with an average of 3-8 days. Similarly, there is no vaccine to prevent adenovirus infection. The main preventive measure to avoid infection is still to develop good hygiene habits.

Physician’s explanation

Can I take medicine by myself after seeing the test results of mycoplasma?

At present, there are many methods to detect mycoplasma pneumoniae infection in clinic, but sometimes the test results are false positive or false negative. Why?

1. Detection of Mycoplasma pneumoniae nucleic acid

The specimen of this detection method is throat swab or nose swab, which can be used for RNA or DNA detection. RNA can be degraded with the death of Mycoplasma pneumoniae, so it can be used as an index to evaluate the infection, prognosis and drug efficacy of Mycoplasma pneumoniae. After the death of Mycoplasma pneumoniae, DNA can still exist in some patients for 7 weeks to 7 months, and it is not easy to degrade, so the DNA test results can not be used to evaluate the acute infection and treatment effect of Mycoplasma pneumoniae.

2. Detection of Mycoplasma pneumoniae antibody
The specimen of this detection method is blood, and some hospitals can collect fingertip peripheral blood. IgM antibody is the most common detection method. Because this antibody generally starts to rise within 1 week of the initial infection, reaches the peak in 2-3 weeks, drops in 3-4 weeks, and drops to the lowest in 2-3 months, therefore, the positive antibody does not mean that the child currently has acute infection with Mycoplasma pneumoniae.

In addition, some hospitals can detect PA (total antibody) in venous blood, and the serum antibody titer of children with mycoplasma pneumoniae is ≥1∶160 as the diagnostic standard of recent or acute infection of mycoplasma pneumoniae, but the positive detection rate is also limited due to the time window limitation of antibody appearance.

To sum up, various detection methods have their advantages and disadvantages. Among them, the RNA detection with high accuracy is limited by the sampling method and the cooperation degree of children, and false negative can also occur; Although IgM antibody detection is convenient, its accuracy is not good. Therefore, parents should not judge by themselves when they see the relevant test results. They need to consult a doctor and listen to professional treatment advice.

With the coming of winter and spring, the temperature in all parts of China has dropped, and the global epidemic situation is in a high incidence period, so the situation of epidemic prevention and control in China is more severe. In this context, China has carried out Covid-19 vaccination for some key populations on the basis of summing up the experience of the early emergency use trial stage, and will strive to establish group immunity protection through active immunization.

What is the significance of this for the overall prevention and control of the epidemic? When can the public be vaccinated except for key people? Where to vaccinate? What should I do if there is an adverse reaction? On December 19th, the State Council Joint Prevention and Control Mechanism held a press conference on Covid-19 vaccination for key population, and invited experts such as Ceng Yixin, the head of vaccine research and development special class of scientific research group of the State Council Joint Prevention and Control Mechanism and deputy director of the National Health and Wellness Commission, to answer the above questions of public concern.

When can the public be vaccinated except for key populations?

Ceng Yixin introduced that from April 2, 2020, when the first vaccine was approved to enter Phase I and II clinical trials, to June, when three vaccines were approved for emergency use, and then to July, when several vaccines went abroad to carry out Phase III clinical trials, the overall progress of vaccine research and development in China was relatively smooth.

"On the basis of summing up the experience in the early emergency use stage, when the winter and spring season comes, China has carried out vaccination work in Covid-19 for some key people, such as cold chain logistics personnel, customs border inspectors, medical disease control personnel, farmers’ market, seafood market staff and public transport staff. This is of great significance for the prevention and control of epidemic situation in China: it not only protects this part of the population, but also facilitates external defense input and internal defense rebound. " Ceng Yixin said.

"The vaccination of this part of the key population is only the first step of vaccination in Covid-19, China. With the formal approval of the vaccine, the vaccination work will be carried out in an all-round and orderly manner for the elderly and high-risk groups with relatively high risk after infection with basic diseases, as well as the subsequent general population. Strive to establish group immune protection through active immunization, so that the COVID-19 epidemic can be controlled more effectively as soon as possible. " Ceng Yixin stressed.

How to achieve group vaccination? Ceng Yixin said: "Relevant departments and units will effectively control the quality of vaccines, and each batch of vaccines must undergo strict inspection; Ensure safe and smooth cold chain transportation and timely and accurate distribution. All localities should carefully design vaccination programs, organize vaccination work in a safe and orderly manner, especially do a good job in medical security during vaccination, timely disposal of adverse reactions after vaccination and monitoring reports; Do a good job in vaccine science, strengthen citizens’ sense of obligation and responsibility to vaccinate under the premise of informed consent, and strive to make high-risk groups’ take over’, and anyone who meets the conditions can be vaccinated on time. "

How safe is the domestic vaccine?

What is the safety of vaccines in China? Zheng Zhongwei, head of the working group of vaccine research and development special class of the State Council Joint Prevention and Control Mechanism, said that China approved the emergency use of Covid-19 vaccine in June and started the emergency use of Covid-19 vaccine in July. Since the emergency vaccination, up to now, more than 1 million doses have been inoculated, and the overall safety is good after adverse reaction monitoring and follow-up observation.

"Among the vaccinated people, about 60,000 people went to overseas high-risk areas for work reasons, and no reports of serious infections have been received so far. In the same period, phase III clinical trials of vaccines for emergency use were carried out overseas, and up to now, more than 75,000 person-times and about 150,000 doses of vaccines have been inoculated. No serious safety hazards have been found in related studies. It is precisely because of this foundation that we have decided to further carry out the vaccination of Covid-19 vaccine in key populations. " Zheng Zhongwei said.

Many people are worried that virus mutation will affect vaccine efficacy. In this regard, Wang Huaqing, chief expert of immunization program of China CDC, explained: "Virus replication will cause mutation. The World Health Organization (WHO), scientific research institutions and vaccine research and development units all pay attention to virus mutation and carry out related research. The current research shows that Covid-19 mutation has no effect on the existing research and development of vaccines. Some time ago, relevant domestic units used antibodies produced by vaccines to conduct neutralization tests on virus strains from different countries. The results showed that vaccines developed in China can produce good neutralization effects on viruses from different sources. "

So is the vaccine protection efficiency 100%? Do people still need to wear masks after vaccination? Wang Huaqing said frankly: "The vaccine protection efficiency is not 100%, and people still need to wear masks after vaccination. Since the virus was discovered in less than one year, the time for vaccine development is shorter, and how long the vaccine protection can last remains to be followed up. "

What should I do if there are serious adverse reactions after vaccination?

Regarding the public’s concern about adverse reactions after vaccination, Wang Huaqing said that in 2011 and 2014, China passed the WHO’s capacity assessment of adverse reactions monitoring in China’s national vaccine supervision system, and the monitoring indicators of adverse reactions of vaccines met or exceeded the WHO evaluation standards.

Jiao Yahui, inspector of the Medical Administration Hospital Authority of the National Health and Wellness Commission, said that vaccination can protect the body and enhance the body’s resistance to infectious diseases, but individuals may have adverse reactions after vaccination, including general reactions and abnormal reactions; There is also a situation called "coupling reaction", which means that the vaccinator is in the incubation period or precursor period of a certain disease when he is vaccinated, and it happens coincidentally after vaccination, which has nothing to do with the quality of the vaccine and does not belong to the abnormal reaction after vaccination. From the previous stage of vaccination in Covid-19, the adverse reactions after vaccination mainly include fever, headache, local induration, local redness, cough, loss of appetite, vomiting and diarrhea.

Jiao Yahui said, "In order to ensure that adverse reactions of vaccination, especially serious abnormal reactions, can be dealt with in a timely and effective manner, the National Health and Wellness Commission requires all inoculation sites to have both inoculation conditions and treatment needs, and has organized and carried out medical treatment training for adverse reactions of vaccination in Covid-19 for medical personnel all over the country, and made personnel and technical preparations in advance for centralized vaccination work."

Cui Gang, head of the CDC of the National Health and Wellness Commission, said that for vaccinators, they should truthfully inform their health status according to the inquiries of medical staff, and stay at the inoculation point for 30 minutes before leaving. After returning home, you should seek medical attention in time if you have abnormal reaction symptoms.(Reporter Yuan Yufei)

　　Chinanews. com client March 15 th (Peng Yuru) Didi taxis let drivers send things. This operation that individual consumers tried before is now arranged for them.

　　Recently, "Didi errands" has been launched, which can provide community residents with daily necessities such as vegetables, grain and oil, medicines and so on. Many netizens joked: "This is the business of grabbing a takeaway brother."

　　Drips on behalf of drivers become errand boys.

　　"At present, the errands will be served by the drip driver." Didi said that it hopes to provide convenience for users and provide more opportunities for drivers to earn income. Dripping drivers take orders for riding electric vehicles every day, and qualified drivers can undertake the errand service as soon as possible after training.

　　At present, this business is only piloted in Chengdu and Hangzhou. "Hangzhou and Chengdu have a very good user base. We hope to pilot in these two cities first, collect user feedback, and gradually expand the city scope after polishing products and services." Didi’s staff explained.

　　Recently, Didi has not announced the number of drivers on behalf of others, but in May 2016, Didi revealed that Didi has covered more than 200 cities in China and has more than 2.18 million registered drivers. This means that if Didi spreads the business nationwide, millions of drivers will be able to participate in the errand business.

　　A little brother in Hangzhou who turns to run errands on his behalf said that this change is only temporary for him. If he can choose, he will still do it on his behalf. "It takes a long time to run errands. For example, some businesses need to wait for meals, or tea shops need to queue up. And driving is a one-on-one service. " In terms of specific income, he said: "It’s not easy to compare when I first started this business."

　　On Didi’s APP, the "running errands" column shows that consumers can summon Didi riders to buy flowers, milk tea, snacks, vegetables and so on. According to media reports, Didi’s errand project is under the responsibility of Didi’s driving team and belongs to Didi Pratt & Whitney’s travel business group. It takes only one week from the project establishment to the launch. At present, most of the drivers are fully engaged in this business, and the second batch of cities will open on March 16th.

　　From "transporting people" to "transporting goods", who is Didi’s opponent?

　　Nowadays, affected by the epidemic, traffic control and personnel travel control are very strict. The number of people traveling has dropped sharply. No matter whether it is online car or driving, the business volume of the service platform of online car type has dropped sharply, and the revenue will inevitably be affected.

　　Data Map: An empty street in Hubei Province, with no pedestrians and vehicles. Peng Ruru

　　"Part of the business is affected and compensated by other businesses, so it is not difficult for Didi to launch the errand business at this time node. It is a win-win situation for the driver to transform into a little errand brother and at the same time guarantee the basic transportation capacity." Chen Liteng, an e-commerce analyst of life service in the E-commerce Research Center of NetEconomy & Society, believes that during the epidemic, the business demand of shuttle passengers decreased, but the demand for running errands and delivering goods to the door surged, which means that new market opportunities have emerged.

　　According to Analysys data, in the first half of 2019, the transaction scale of China’s home business market reached 358.72 billion yuan, which continued to rise. The large-scale development of home-to-home business directly drives the immediate delivery demand and order quantity to increase greatly.

　　However, there are quite a few players who run home business. JD.COM, Meituan, Ali and Suning all have home business. In addition, there are startup companies that mainly run errands, such as UU running errands and flash delivery, and express delivery companies such as SF Express also join the competition through the same city distribution.

　　In October 2019, SF officially announced the launch of the "SF Express in the Same City" brand. It is understood that SF Express has covered more than 200 cities. At the level of delivery speed, its business positioning is 0.5-1 hour delivery on average.

　　The strength of the delivery of the US Mission and the matching of hummingbirds is also good. In May 2019, Meituan officially launched a new brand "Meituan Distribution"; On June 5th, Ali acquired Hungry and announced the independence of "Hummingbird Matching", relying on hungry delivery riders to support business development.

　　Experience: people in different places are still unable to place orders for pilot cities.

　　At present, Meituan, SF, Ali, JD.COM and others have better business experience in "freight" than Didi, and it takes time for Didi to change from "transporting people" to "freight" and accumulate business experience.

　　The author noticed that there was a sentence in the introduction of Didi Paotui: "I can buy things for you and send flowers to your girlfriend in different places … …” In other words, even in City A, the orderer can fill in the address of City B, check the "Buy Nearby" option, and give things to friends in City B..

　　However, it is found in practice that the author who is currently in Hubei wants to place an order and run errands for his friends in Hangzhou, and can’t modify his city positioning in the column of receiving information. The customer service consultation in Didi Travel APP has no option to run errands. The author asked questions about placing orders in different places through Weibo, the official running errands of Didi. As of press time, the staff had not given an effective answer.

　　In terms of billing, the announcement of Didi’s errands shows that the cost of running errands within 4 kilometers is 12 yuan; 4-10 kilometers is 20 yuan; More than 10 kilometers is 30 yuan. At the same time, it is stipulated that the weight of a single purchase is less than 10kg, and the price does not exceed that of 500 yuan. The US Mission’s errand charging rules show that the basic delivery fee (within 3 kilometers) is 10 yuan; For the part of 3-100 kilometers, the 2 yuan will be increased every kilometer. In addition, the US Mission also stipulated a weight surcharge and a special time period fee. Comparatively speaking, the charging rules of the US Mission’s running errands consider more comprehensive scenarios.

　　According to the data of Ai Media Consulting, the improvement direction of users’ expectations for home-to-home services in local life services is mainly focused on price and delivery quality. 36.7% of consumers expect higher cost performance of goods and services, and 33.9% of consumers hope to have more preferential promotions. At present, Didi errands have no obvious advantage in price.

　　In the cross-border operation of Didi, do you still remember Didi takeaway?

　　Didi’s running errands is not the first time Didi has tested the local life service field. In 2018, Didi takeaway was in 9 cities — — Merchants were recruited in Wuxi, Nanjing, Changsha, Fuzhou, Jinan, Ningbo, Wenzhou, Chengdu and Xiamen. At that time, Didi Takeaway was considered by many people to be the biggest competitor of Meituan Takeaway.

　　Data map: Outside the SOHO office building in Wangjing, Beijing, many take-away food delivery staff are waiting for the orderer to come and pick up the meal. China News Service reporter Hou Yushe

　　On the 13th, the author called Didi Takeaway Customer Service and learned that at present, only five cities, namely Wuxi, Taizhou, Zhengzhou, Nanjing and Chengdu, continue to open their services, which is 4 fewer than when they first laid out. However, Didi did not seem to stop. At the end of 2019, Didi announced that it would launch an online food delivery service in Japan in 2020. At present, the Mexican-Japanese interface has appeared on Didi Takeaway official website.

　　Not only to the home business, Didi also has a layout in the financial and insurance business fields. Recently, Didi has obtained an insurance license by participating in the increase of modern property insurance. On March 10th, the approval of China Banking and Insurance Regulatory Commission official website showed that the registered capital of Hyundai Property Insurance increased from 550 million yuan to 1.667 billion yuan. The four new shareholders introduced in this round of capital increase and share expansion include Lenovo and Didi Dirun Technology. Among them, Lenovo and Dirun Technology will each hold 32% of the shares, tied for the second largest shareholder.

　　The "Financial Services" column in Didi Chuxing APP includes many businesses such as loan, wealth management, medical care and auto insurance. In 2017, Didi also cooperated with more than 20 small and medium-sized property insurance companies and insurance assessment companies to establish "China Insurance Automobile Service Technology Service Co., Ltd.", with the aim of creating an open and shared Internet auto insurance claims platform. At present, Didi has cooperated with insurance companies such as China Ping An and Pacific Insurance.

　　Didi is so active in cross-border, which is not unrelated to the expansion of competitors’ boundaries. After all, Meituan also has a water taxi service, and SF Express is also expanding its business boundaries. Perhaps, for Didi, its penetration rate of "transporting people" already has a comparative advantage. What I want to do now is to let users accept the change from "transporting people" to "transporting goods".

　　So, can you use Didi errands?

step describe 1. Market research Property buyers first need to conduct market research to understand the detailed information of different auction projects, including the reputation of developers, the location, planning and price of the projects. 2.

As the weather becomes colder and colder, the human body will also react, for example, blood pressure may fluctuate. Therefore, besides wearing clothes to keep warm, we should also pay attention to the changes of blood pressure and beware of the "silent killer" of high blood pressure.

Hypertension will not only increase the risk of cardiovascular and cerebrovascular diseases, but also cause a series of serious health problems. Fortunately, hypertension can be effectively controlled through early monitoring and management. So, how to realize the early detection of hypertension and take appropriate management measures?

At least one in five adults has hypertension,

About 80% of patients failed to get adequate treatment.

In 2023, the World Health Organization released the Global Hypertension Report, which showed that the number of patients with hypertension in the world has doubled in the past 30 years, from 650 million in 1990 to 1.3 billion in 2019. Among them, nearly half of patients with hypertension don’t know their own illness, and about 80% of patients have not been adequately treated. According to the "Guidelines for the Prevention and Treatment of Hypertension in China (Revised Edition in 2024)" issued by the China Guidelines for the Prevention and Treatment of Hypertension, the weighted prevalence rate of hypertension among adults over 18 years old in China was 27.5% in 2018. It is equivalent to at least one hypertension in every five adults.

It is noteworthy that the prevalence of hypertension among young and middle-aged people is on the rise.Hypertension in young and middle-aged people is mostly "hidden" and has no obvious symptoms in the early stage. For them, early identification and management of hypertension is particularly important.

Hypertension is closely related to the complications of heart, brain, kidney and blood vessels, which can easily lead to a series of serious health problems. The guideline points out that there is a close causal relationship between the blood pressure level in the clinic and the risk of cardiovascular and cerebrovascular diseases and death.Every liter of systolic blood pressure of 20 mm Hg or every liter of diastolic blood pressure of 10 mm Hg increases the risk of cardiovascular and cerebrovascular diseases. Besides cardiovascular risk, hypertension is also an important risk factor for chronic kidney disease. Elevated blood pressure is also closely related to dementia.

Effective prevention and control of hypertension is not only an important guarantee for individual health, but also an important measure to curb cardiovascular and cerebrovascular diseases. It has become a top priority to optimize the management and treatment of hypertension and improve the public awareness rate.

To control blood pressure, the first thing is to measure it regularly and find it early.

Do you know your blood pressure at different times? Blood pressure measurement is very important for blood pressure control. In the guideline, clinic blood pressure measurement is no longer the only means to diagnose and evaluate hypertension, and clinic blood pressure, family blood pressure and ambulatory blood pressure level can all be used as the basis for hypertension diagnosis. Among them, ambulatory blood pressure has attracted more and more attention, especially in identifying hidden, white coat and nighttime hypertension. Ambulatory blood pressure monitoring has advantages, which can evaluate blood pressure risk more accurately and comprehensively. Ambulatory blood pressure values also provide doctors with the basis for making treatment plans.

Ambulatory blood pressure monitoring also plays an important role in the management and control of hypertension. By judging the blood pressure readings of the human body in different time periods and different living conditions, it can help the public to understand and master the laws and characteristics of their blood pressure fluctuations in time.

With the technological innovation in the industry, wearable blood pressure measuring equipment came into being. Compared with traditional electronic sphygmomanometer, wearable devices break through the limitation of blood pressure measurement environment to a certain extent, and users can monitor blood pressure anytime and anywhere, significantly increasing the number of blood pressure measurements.

"Guidelines for Prevention and Treatment of Hypertension in China (Revised Edition, 2024)" mentioned that up to now, wearable wrist electronic sphygmomanometer and wristwatch with oscillometric technology have passed the accuracy verification and can be used for daily blood pressure monitoring.

Wang Jiguang, director of hypertension department of Ruijin Hospital affiliated to Shanghai Jiaotong University School of Medicine.

On November 26th, 2024, Huawei watch d2 was unveiled, which is Huawei’s second-generation wrist ambulatory blood pressure recorder. It first supported ambulatory blood pressure monitoring and has obtained 7 global medical certifications. As a representative of ambulatory blood pressure monitoring equipment, Huawei watch d2 is light and thin, which can bring users a comfortable wearing experience and make daily blood pressure monitoring more portable.

Huawei watch d2 is equipped with Xuanji sensing system, and adopts blood pressure fusion algorithm and ultra-narrow mechanical airbag to realize medical-grade accurate ambulatory blood pressure measurement, and can generate ambulatory blood pressure report to show the user’s blood pressure data all day. At the same time, Huawei watch d2 has been adapted and adjusted by real user data to ensure that users can accurately measure blood pressure whether standing, sitting or semi-lying. When sleeping at night, the airbag automatically inflates and measures, and the pressure is stable, which is not limited by sleeping posture and does not affect the quality of sleep.

At the same time, users can also view family blood pressure health reports, timely reminders of abnormal blood pressure data and other health data at any time in the family space of HUAWEI Health app on the mobile phone, so as to protect family health remotely.

In addition to monitoring blood pressure,

And do these things well.

Lifestyle is a very important reason for the large number of patients with hypertension. Whether it is to prevent or manage hypertension, we should do the following things well.

0one

Low sodium diet

A low-sodium diet is good for controlling blood pressure. The guidelines point out that all patients with hypertension should take various measures to limit their sodium intake. Those with good renal function are recommended to choose low sodium and rich potassium instead of salt. The guideline makes it clear that compared with common salt, low sodium and rich potassium salt can significantly lower blood pressure, reduce stroke and reduce the risk of cardiovascular events and death.

A study published in the Journal of the American Medical Association in 2023 found that a low-sodium diet can reduce systolic blood pressure. The researchers said in the paper that the effect is similar to that of commonly used first-line antihypertensive drugs.

02

Moderate exercise

The guide emphasizes that for hypertensive patients with well-controlled blood pressure, mixed training with aerobic exercise as the mainstay and resistance exercise as the supplement is recommended, and it is also recommended to combine breathing training with flexibility and stretching training.

A study published in the Journal of Clinical Hypertension in 2021 found that after walking for 3 months, most people’s blood pressure dropped by about 2-3 mm Hg. According to the researchers, for patients with hypertension, walking 4000-8000 steps a day can achieve ideal results in reducing hypertension.

0three

Regular schedule

The guide has added some suggestions about sleep in the intervention chapter of treating life style. Patients with hypertension should keep healthy sleep and improve sleep disorders. Healthy sleep includes adequate sleep time and good sleep quality. Shorter sleep time will increase the risk of hypertension, and insomnia is related to cardiovascular death and all-cause death.

It is recommended that adults sleep for 7-9 hours every night to ensure the quality of sleep and work and rest on time.

0four

Stay away from alcohol and tobacco

According to the guideline, smoking is recognized as an independent risk factor of cardiovascular disease and death, and the greater the smoking amount and the longer the smoking time, the higher the risk of cardiovascular disease and death. Secondhand smoke exposure also increases cardiovascular risks such as coronary heart disease and stroke. In addition, the frequency of drinking increases, and the risk of hypertension will also increase.

0five

Managing stress

With the rapid development of social economy, the pace of life is accelerating, social competition is becoming increasingly fierce, and psychological pressure caused by various factors is gradually increasing. Patients with hypertension are more likely to have mental and psychological problems.

In short, regular monitoring of blood pressure and a good lifestyle can achieve the goal of stable blood pressure. Enjoy health every day!

Xinhua News Agency BeijingSeptember 13th (Reporter Pan Jie) The 11th meeting of the 14th the National People’s Congress Standing Committee (NPCSC) voted on the 13th to adopt a decision on amending the Statistics Law, which will take effect as of the date of promulgation. On the basis of keeping the current statistical law system framework basically unchanged, this revision of the statistical law focuses on strengthening the responsibility of preventing and punishing statistical fraud, strengthening statistical supervision, and improving the scientific nature of statistics, adding 3 new articles and modifying 21 articles.

 

Shi Hong, director of the Social Law Office of the National People’s Congress Standing Committee (NPCSC) Law Committee, said that the revision of the statistical law adheres to the problem orientation, enriches the basic statistical functions such as statistical supervision, supplements and improves the basic statistical systems such as statistical investigation, national economic accounting, statistical data management and publication, strengthens the legal responsibility for illegal acts such as statistical fraud, and fills in the shortcomings and weaknesses of the legal system.

 

In terms of preventing and punishing statistical fraud, the revision of the statistical law has increased.It is stipulated that "prevention and punishment of statistical fraud and fraud shall be included in the scope of responsibility for administration and performance of duties according to law" and "strengthening the assessment and management of leading cadres’ statistical work", and that "subordinate units and their personnel or statistical investigation objects shall not be explicitly or implicitly filled in with false statistical data" and "units and individuals who perform their duties according to law or refuse or resist statistical violations shall not take revenge".

 

In view of the behavior of the responsible person who neglects the serious inaccuracy of statistical data, the revision of the statistical law further increases the legal responsibility; Increase the provisions of the bottom, throughThe way of "enumerating and covering the bottom" ensures that all kinds of statistical fraud and fraud are fully investigated for legal responsibility.

 

Mao Shengyong, deputy director of the National Bureau of Statistics, introduced that in strengthening statistical supervision, the revision of the statistical law further clarified the connotation, functional orientation and requirements of statistical supervision"The state builds a systematic, coordinated, efficient, powerful, authoritative and reliable statistical supervision system" and "statistical institutions conduct statistical supervision on the implementation of major national economic and social policies and measures and the performance of statistical statutory duties in various regions and departments according to the statistical investigation system and approved plans".

 

This revision also makes some more targeted and operational provisions on improving the government’s statistical production capacity, data quality and service level, includingAccording to the new situation of economic and social development, we should improve scientific and reasonable statistical standards and statistical index system, and bring new economic fields into the scope of statistical investigation. The state implements a unified national economic accounting system, promotes the deep integration of modern information technology and statistical work, and promotes the electronization, digitization and standardization of statistical accounts.

Garbage is a misplaced resource. How to make waste "turn waste into treasure" and do a good job of classified recycling is very important. In Nanchuan, a "two-network integrated recycling service point" is a concrete practice to promote the recycling management of renewable resources.

In order to start from the source recycling and create a new model of "fixed-point, fixed-time, fixed-car" recycling of renewable resources, Nanchuan District Urban Management Bureau has promoted the standardization of recycling industry and further improved the recycling rate of urban domestic waste by integrating the collection and transportation system of urban domestic waste with the recycling system of renewable resources.

Recyclable materials are collected at home.

The recycler is sorting, packing and loading the recycled materials.

Recently, An Shuiquan, a recycler who has been busy all morning, is sorting and packaging recycled waste paper boxes, plastic bottles, cans and other recyclables at the two-network integrated recycling service point outside Longji Community.

"The service point has been running for two years, and all we have to do is garbage sorting, door-to-door recycling, subdivision and packaging." An Shuiquan told reporters that he is responsible for the recycling of recyclables in four nearby communities every day, with an average of about 500 kilograms a day.

"Start at 7: 30 every morning and ride a tricycle to various communities for recycling." An Shuiquan said that the property management of the community will also inform the owners in advance, so that everyone can bring their own recyclable materials to the designated concentration point of the community, and then weigh and settle accounts. "Like everyone usually unpacks express cartons, we will pay 80 cents to residents for recycling 1 kg, and 89 yuan for cans 1 kg."

For residents with mobility difficulties, the staff of the two-network integration recycling service point will also provide on-site service. "Our website has published the telephone number, so just call if necessary."

68 recycling service points have been built in the whole region.

Residents send waste materials to recycling service points.

Since 2023, Nanchuan District Urban Management Bureau and District Commercial Committee have started the construction of integrated recycling service points of sanitation system and renewable resources recycling system, and gradually built the whole process system from the source to the end, such as integrated recycling service points, transfer stations and distribution yards.

Among them, the two-network integrated recycling service points specially set up in residential areas, public places or commercial squares are recycling places for recycling, sorting, storing and transferring recyclable materials in the classification of domestic waste of residents and units; The street (township) regional two-network integration transfer station is a recycling place for centralized recycling and storage of domestic renewable resources, and has the functions of sorting, packaging and transshipment; The two-network integrated distribution center with the service scope of the district is a large-scale distribution center for renewable resources of life source, which can meet the annual recycling and distribution volume of more than 200,000 tons and has the functions of commodity trading, sorting and processing, warehousing and distribution and supporting services.

Chen Hongying, head of the Domestic Waste Classification Office of Nanchuan District Urban Management Bureau, said that according to the principle of easy delivery, 68 two-network integrated recycling service points with unified identification signs and facilities and equipment specifications have been built in the whole region, realizing the full coverage of renewable resources recycling services in the region.

"At present, we are planning measures to make an appointment for home recycling and discount supermarket shopping, and call on more residents to participate in garbage recycling." Chen Hongying said that the former will introduce a "digital door-to-door reservation recycling management" system, so that residents can recycle online and offline like express delivery; The latter cooperates with local supermarkets and convenience stores in Nanchuan, so that residents involved in garbage recycling can realize shopping discounts and play a better incentive role.

In addition to the small and light recyclables produced in daily life, Nanchuan took the lead in exploring the large and heavy recyclables such as worn-out furniture in Xicheng Street last year, relying on the social governance network, and implementing the modes of "party building+property" and "party building+voluntary service", and embarked on a "city management department guidance+community inspection and filing+enterprise professional service+online reservation+door-to-door collection and transportation".

This move not only makes the large-scale garbage that has long plagued the community environment be utilized as resources, but also saves the cost of the management department, at the same time, it maximizes the reduction of the source of domestic garbage, and comprehensively creates a good atmosphere of "citizen participation is hot, community development is dynamic, and cadres have responsibilities".

In areas such as old residential areas, back streets and alleys, and dead corners of environmental sanitation management, the local authorities give full play to the role of community grid workers and cleaning staff, strengthen the frequency of inspections in the responsible areas, and timely discover and report the large pieces of garbage discarded by citizens and appearing on both sides of the road, and get in touch with recycling enterprises and cooperate with them for disposal.

In the property management community, a special area for large-scale garbage is designated, which is collected, transported and disposed of by recycling enterprises on a regular basis. At the same time, recycling enterprises open their contact information to the public through multiple channels, and provide large-scale garbage to make an appointment for door-to-door removal and disposal services to further optimize the mode of facilitating the people and benefiting the people.

Yao Tao, secretary of the Party Committee and director of Nanchuan Urban Management Bureau, said that promoting the "two-network integration" between the collection and transportation system of municipal solid waste and the recycling system of renewable resources is an important measure to improve the efficiency of municipal solid waste treatment and the level of resource recycling. The District Urban Management Bureau will continue to do a good job in garbage sorting, strictly regulate the management of recycling of renewable resources, and continue to promote the recycling service of renewable resources to be more accurate and efficient.

Tesla’s brakes have failed again, and such news will appear every once in a while. But if we ask further, what happened in the end, not many people can answer. Every major traffic accident in Tesla has turned into a farce vent: people who hate Tesla are like the New Year, shouting that Tesla’s brakes are out of order and disregard for human life; Tesla’s diehard fans are convinced that the owner is lying, gnashing his teeth and praying that he must let the bottom of the prison sit through.
　

Unfortunately, I didn’t see any reliable analysis on the whole Chinese Internet. I’ll do it. After reading this article, you will know more about Tesla’s braking problems than most onlookers, and everyone should know what Tesla has done-after all, we are all traffic participants.
　

First, the mandatory "single pedal mode"

　

Especially in the past two years, Tesla’s sales have been unprecedented. But even so successful, Tesla has sold hundreds of thousands of cars in China. You know, there are more than 300 million cars in China, and there are nearly 500 million driver’s licenses, so no matter what, only a small number of people have driven Tesla in China.

　

Tesla has a unique setting: forced single pedal mode.

　

Most people are confused when they hear this word. "Single pedal? What do you mean by that? Is there only one pedal under the feet of Tesla owners? "

The masses are full of confusion and curiosity about the single pedal, and Tesla fans and Tesla fans are another grand occasion. The single pedal mode will be shown off as a unique advantage in the circle of friends of Tesla sales specialists. Many Tesla owners also proudly put a single pedal on their lips: "I basically don’t step on the brakes now." "The single pedal mode is too fragrant."

Salespeople regard "single pedal" as a selling point.

The single pedal mode is not that Tesla has only one pedal at his feet. On the contrary, Tesla’s driver’s seat is exactly the same as all other automatic cars. It’s all a deceleration pedal(Brake), an accelerator pedal(throttle), this makes no difference.

　

The problem is that Tesla quietly changed the usage of the accelerator pedal.

　

On Tesla, stepping on the accelerator is accelerating, and releasing the accelerator is equivalent to stepping on the brakes. This is a mandatory setting of Tesla and cannot be changed. Don’t tell me about other cars. Tesla is the only one who can’t change the single pedal.
　

Although Tesla gave three stop modes,(Slow down, rotate, hold)Optional, but these three modes are only different at very low speed.(The "Slow" mode is similar to the idle speed of ordinary cars, while the "Hold" mode can completely stop as long as the accelerator is released.). As long as Tesla releases the accelerator when driving, the car will decelerate sharply. Deceleration force(g value)In other cars, it can only be achieved by stepping on the brakes. Of course, when Tesla releases the throttle while driving, the brake light does light up, which also shows that "releasing the throttle" on Tesla can achieve the braking effect of "stepping on the brakes" of other cars.

　

This is why many Tesla owners say that they haven’t stepped on the brakes for a long time: when driving Tesla, they step on the accelerator when they want to accelerate, and when they want to brake, they loosen the accelerator. The brake pedal is really not available.
　

Friends who haven’t driven Tesla have to ask again: according to you, since the accelerator can achieve the braking effect, why do you need to brake the pedal? Just give one accelerator pedal, won’t it? I can’t either. In layman’s terms, the looser Tesla’s throttle is, the stronger the braking force is, but even if the throttle is completely released, it is only a "strong braking" rather than a "full braking". If a child suddenly crosses the road in front of you and you find that the braking force provided by loosening the throttle is not enough, you need to step on the brake pedal to brake.
　

Is the above paragraph a little confused? Just be confused. Because it is indeed a more complicated operational logic.
　

Now let’s look back at the pedal logic of a normal car:

　

Pedal of normal car

Tesla’s pedal logic is like this:

　

Tesla’s pedal

So Tesla’s pedal is more complicated.It seems to be a "single pedal", but in fact it cannot be separated from the brake pedal. It still needs two pedals like those traditional cars that Tesla fans think are old-fashioned. Tesla only integrates most operations on the accelerator pedal, and the brake pedal has become an irreplaceable but almost neglected scheme in an emergency.
　

Second, "defensive driving" and "preparing for braking"

　

If you didn’t know what "defensive driving" was, please read this paragraph very, very carefully. These few minutes may benefit you and your family for decades to come.
　

The so-called defensive driving, in fact, is not too profound. In a word, it can be made clear: don’t wait to see the danger before taking measures, predict the possible danger and prepare for it in advance.

　

It’s that simple.

　

Someone said again, I’m not a prophet. How do I know if there will be danger?
　

When you are not sure whether danger will happen, prepare as if it will happen. Your vigilance is by no means superfluous.

　

If the most important safety concept of driving is defensive driving, the core and basic operation of defensive driving is "preparing for braking".

A normal car must be braking in this scene. Tesla is not.

A typical and common scene: you drive past the gate of a primary school that has just finished school. There is a lot of traffic at the gate of the school. A group of children are standing on the side of the road, and several children are shouting excitedly at the children across the road. What are you going to do at this time? Any high-level assisted driving will not recognize that the children on the roadside are ready to move. It’s good that those sensors can find people on the roadside, let alone tell their age and predict their behavior. As a homo sapiens, the absolute overlord of primates, you can easily know that these children are likely to suddenly cross the road. Therefore, experienced drivers will "prepare the brakes": put their feet on the brakes in advance. Don’t step on it, but be ready to step on it.

　

Children, at the first sign of wanting to cross the road foolishly, step on it at once! Slow down at any time and stop completely at any time!
　

If the children are just chattering on the side of the road without further action, then prepare the brakes and wait until they pass before accelerating.
　

Safe and efficient.

　

Therefore, the seemingly simple action of "preparing the brakes" is actually extremely necessary! It means that the driver actively chooses to enter the defensive state. In this state, the car put an end to all the possibility of wrong acceleration and can only slow down. This is the safest operation method in complex road sections.
　

Tesla’s forced single pedal mode destroyed the driving skill of "preparing for braking". It is impossible to prepare the brakes when driving Tesla, but you must step on the accelerator. Because if you don’t step on the accelerator, the car will almost stop or even stop completely. If you want to drive Tesla at a normal constant speed, you can’t leave the accelerator with your feet.
　

Tesla’s forced single pedal mode forces the driver to step on the accelerator on all sections that should be braked.
　

In addition to "preparing for braking" when driving a normal car, the muscle memory formed by quickly switching the pedal of the foot creates an extra double insurance: every driver who often "prepares for braking" has to quickly move his foot from the accelerator to the brake for countless times every day, and this action has formed an instinct after hundreds of thousands of repetitions. Braking has been able to handle most emergencies safely and calmly, and once there is no warning and even the brakes are not ready, this subconscious action of suddenly losing the accelerator and stepping on the brakes can also avoid accidents.
　

Tesla changed it, too. There is no punishment for suddenly releasing the throttle in a normal car, and the car will continue to maintain its previous state; On Tesla, you can’t suddenly loosen the throttle, because it is equivalent to stepping on the brakes. Therefore, every Tesla driver is forced or enjoyed to "precisely control the throttle" every day.
　

Tesla forcibly changed the driver’s car pedal operation habits. Disabled the safety backup skill of "preparing for braking" and the training of "quickly switching pedals", which actually disintegrated those beneficial muscle memories.

　

The throttle is a switch that releases huge energy, just like the trigger of a gun. Similarly, just as the finger can’t be put on the trigger when the gun is not in use, the foot should not be stuck on the accelerator for a long time when the car is not accelerating.
　

Third, "single pedal mode is too fragrant"

　

But unlike what I wrote, the single pedal mode is an advanced and easy-to-use setting among Tesla fans. The single pedal mode is an advanced, fashionable and even a good thing that you can’t go back after using it.

Common Tesla fan talk

Tesla fans will say that I have no problem driving for so long. If you think that the single pedal mode is not good, or you are not used to it, just get used to it; Either your driving skills are not good and you are not suitable for driving. In fact, if I have to ignore the fear of traffic accidents, I also feel that a single pedal is quite convenient to drive.
　

but I cannot do it. I can’t accept that my foot should step on the accelerator when there are pedestrians in front of me or there are blind spots.
　

Nowadays, the society is harmonious. People in shooting games are shot with golden light or cement, and many people have never seen blood. Many people think that driving is to be isolated from the world in a comfortable private space. Many people think that driving is to put a bunch of dolls in the car and hand-made plush toys, stick a few warm or funny stickers, and excitedly think that the boss of this car will board Mars and enjoy the elegance and leisure of middle-class life … …

　

I’m telling you, that’s not true. Driving is an activity that will kill yourself or others at any time if you don’t keep up your spirits. When I was in middle school, the school would hold a traffic accident warning exhibition, which was full of bloody photos of the accident scene. While you were afraid and curious, you would have a deeper understanding of the traffic incident than ever before.

　

It turns out that the living people and cars we usually see will turn into a pile of scrap iron and a mass of flesh and blood in the accident.
　

Just like me, you don’t want to step on the gas in front of pedestrians. I won’t feel that "single pedal is not a big problem" and "just get used to it".

　

Stripped of the fear of accidents, Tesla’s single pedal can skillfully make some drivers with high risk tolerance enjoy it. It captured groups of die-hard fans through an abusive transformation:
　

From the first time I heard about the novelty of single pedal mode, to the thrill of driving Tesla without stepping on the brakes, to the sense of accomplishment of getting used to skillfully controlling the vehicle only by the accelerator without stepping on the brakes after training, and finally to the psychological superiority of others. Drivers who skillfully use and enjoy the single pedal will think that it is a learned, unique and advanced skill that others do not have.(Actually, it’s not)There is a strong superiority in all the manners. Much like the way I bragged with other students after eating the terrible McDonald’s for the first time more than 20 years ago.
　

What is particularly ridiculous is that since the emergence of Tesla’s forced single pedal mode, many Tesla fans touted the single pedal mode as labor-saving, saying, "I don’t have to step on the brakes frequently anymore, and I used to be exhausted by stepping on the brakes." I heard that someone’s waist is tired because of uncomfortable seats. I heard that some people are tired of their arms and shoulders because of the unreasonable ergonomic design of the vehicle, and the steering wheel is too forward. I also heard that some people are sleepy and tired when driving because they don’t sleep well at night. But the first time I heard that someone was "tired" because of "stepping on the brakes", I was still shocked and speechless-Are the brakes there to save you effort?
　　

In order to defend their views or positions, many Tesla fans sometimes have a strong desire to fight and can’t listen to any criticism of Tesla. Today, I’m going to say it again in an ugly way. I hope you can calm down and think about it: if your children leave school and a group of children cross the zebra crossing. Some children even chase and fight on the road. At this time, several cars with hundreds of horsepower can break through the school gate in three to five seconds. Do you prefer the drivers’ feet on the accelerator or the brakes?

　

4. Didn’t other cars step on the wrong accelerator?

　

Did you deliberately hack Tesla? Don’t other cars that don’t have a single pedal step on the wrong one?

　

Of course there is.
　

Before Tesla’s forced single pedal mode appeared, there were all kinds of news around the world that the accelerator was used as a brake.

　

But one thing we can be absolutely sure of:Some people make mistakes in simple logic, and complex logic will only make mistakes more easily..

　

Tesla’s pedal logic is more complex logic, which I have described in detail earlier. Or it can be said that Tesla’s brakes are two-stage. When the braking force provided by the accelerator is not enough, it is necessary to switch the pedal from the original "lifting the brake to slow down" to the brake pedal and then "step down" to achieve further braking. So this logic is more complicated than traditional cars: "lifting" is also slowing down, and "stepping" is also slowing down. To achieve a braking force from the establishment to the maximum action on Tesla, sometimes it is necessary to switch the pedal once in the middle!

　

In case of emergency, other drivers: step on.

Tesla Driver: Lift the throttle-lift the throttle again-find that it can’t stop-choose the right pedal.(Brake)-step on it.

　

When Tesla drivers get used to the long pedal on the right, which used to be called "accelerator", and when Tesla owners’ first reaction is "lift" in case of emergency, it is also powerless for Tesla fans to emphasize that "I won’t make mistakes at critical moments". Every time Tesla drives, he intensifies the throttle deceleration and downplays the existence of the brake pedal. What makes you think that you can remember the pedal that has not been used for a long time quickly and accurately at the critical moment?

This is the wrong operation of the trainer.

　

If Tesla dares to make the accelerator pedal: full acceleration when stepping on it, and full braking when lifting it, then this is the real single pedal-so there is no need for braking at all, and stepping on it can be fully responsible for acceleration and lifting it is fully responsible for deceleration, which is fine-at least logically concise. But at this time, you will find that there is no difference between this and the double pedals of a normal car. The only change is that you are a little more tired.

Every seemingly boring safety regulation is followed by a bloody accident lesson.

　

Five, "single pedal mode to save electricity"

　

Speaking of this, Tesla still has one rhetoric left, that is, "saving electricity."
　

Many netizens also have misunderstandings that Tesla’s forced single pedal mode is designed to save electricity and increase battery life.
　

Wrong.
　

"Kinetic energy recovery" is a very common basic function in electric vehicles. Not only do you have Tesla, but all the imported joint ventures, domestic expensive and cheap electric cars, including hybrid cars, that we can name. Part of the wasted energy is recovered for reuse, so it is "energy-saving" and "low energy consumption", that is, "running far away".

　

It’s all the same principle.

　

The only difference is that other cars integrate "kinetic energy recovery" into the brakes. Tesla, you put "kinetic energy recovery" on the accelerator.
　

You also recycle, he also recycles, and everyone is recycling. The single pedal mode will not save half a degree more electricity than others’ "double pedal mode".

　

When other cars hit the brakes, they were recycled for you unnoticed. How do you drive? You don’t have to change your habits, you don’t have to relearn, and you don’t even realize it! The car accurately combines electric braking and mechanical braking, and the work of "kinetic energy recovery" is finished.

　

If you have to say anything about high technology, it’s called high technology.
　

Tesla put kinetic energy recovery on the accelerator, so he slowed down as soon as he released the accelerator. You’re not an advanced thing. It’s just that people recycle it when they step on the brakes, and you recycle it when you loosen the throttle, that’s all.

　

Other cars have CRBS system, so they can complete the work of "kinetic energy recovery" under the condition that the brake foot feels very smooth. Tesla has no CRBS, so it is difficult to achieve efficient and smooth cooperation between mechanical braking and electric braking. Perhaps for this reason, Tesla simply put "kinetic energy recovery" on the accelerator.
　

Tens of thousands of domestic electric vehicles have CRBS, but Tesla doesn’t.

　

So please, don’t say that Tesla’s single pedal mode is high-tech. In my opinion, it is because of the lack of more advanced software and hardware.（CRBS）, can only be forced to forcibly change the driver’s operating habits. That’s what happened.

　

Everybody repeat after me, single pedal, no power saving!
　

Six, "brake failure"

　

You can see that I don’t like Tesla very much. But I want to say a word for Tesla today:The probability of Tesla’s brake failure is too small.

You must have stepped on the wrong foot.

When Tesla adopted the forced single pedal mode, I would like to attribute all its "brake failure" news to "stepping on the wrong foot". Because forcing the single pedal mode is simply the wrong operation of the trainer. At the same time, the safety redundancy of modern automobile brake system is great, even for brands like Tesla. Even if the ESP system fails, the ibooster system rarely fails at the same time, and it also needs the mechanical braking system to fail. It cannot be said that the probability is completely zero, but the probability is infinitely close to zero.

　

I include many experienced drivers with excellent driving skills. I have read countless cars, and the track is also very colorful. The response speed of driving experience is better than that of ordinary people. But when we drove Tesla, we were very uncomfortable and panicked. Yes, but we can clearly feel the discomfort of forcibly changing safe driving habits. On the contrary, many novice drivers swear that they will never get confused.

　

Tesla removed the dashboard, made the door handle hidden, and made the skylight unobtrusive. I think these are minor problems, but they are just not easy to use. But the use of the throttle is a matter of life and death. Why do you change it?
　

Tesla, why did you change the usage of the throttle?

Nowadays, many young people and fashionable men and women love to buy Tesla. Dress beautifully, take a photo of the car, and be beaming. In their eyes, they just bought a beautiful and fashionable new car, which is a happy thing. But in my opinion, I am very uneasy because they are forced to drive in the forced single pedal mode. They will be constantly trained to use the throttle to slow down, and there are very few real emergencies-I dare not think about the probability that they will step on the wrong foot when an emergency occurs. Hundreds of thousands of high-powered electric vehicles with forced single pedal mode are driving on our highway, and they are stepping on the accelerator when others are stepping on the brakes.
　

Today is November 16th, 2022. I put it here, Tesla’s single pedal mode will definitely be changed later, and CRBS will definitely be added. Because although many Tesla fans say that a single pedal is an advantage, I believe that even companies like Tesla who are keen on forced innovation must clearly know that a single pedal is not easy to use. When the time is right, they will certainly get rid of this neglected mistake.
　

Only then, those casualties caused by stepping on the wrong pedal will probably be forgotten by people.
