Driving back during the Spring Festival, these sections of Harbin are prone to congestion.

With the Spring Festival holiday coming to an end, the peak of the return trip to visit relatives has begun from the fourth day of January 25th. In order to ensure the safety of the return trip, the traffic police department of Harbin Public Security Bureau has studied the traffic flow of national and provincial highways, the characteristics and occurrence of traffic accidents and the traffic characteristics of important sections over the years during the Spring Festival holiday, and issued a return trip reminder in combination with the actual situation this year.
The return traffic flow is running at a high level in stages, so be prepared in advance. As the total passenger flow during the Spring Festival this year has increased significantly, from the perspective of road traffic flow, the peak of returning to the city after the Spring Festival will appear on the fourth day of the first month, especially during the festival, many southern tourists drive to Kazakhstan and gradually start to concentrate on returning.
According to the pre-judgment,Highways and national highways with large traffic flow are: Harbin-Dalian Expressway, Harbin-Nantong Expressway, National Highway 102, National Highway 202, Hamu Expressway, Jingha Expressway, Airport Expressway and Old Airport Road; Urban roads with large traffic flow are: Xuefu Road, Xianfeng Road, Third Ring Road, Hexing Road and other main streets.
The traffic police department will strengthen the deployment of police force at the entrance and exit of the city and the toll station of the expressway, strengthen the guidance of surrounding roads, and strengthen the patrol control of expressways connected with other cities to avoid long-term and large-scale traffic congestion across regions.
In case of queue for vehicles entering and leaving the city, please reasonably bypass the entrances, toll stations and surrounding roads. In case of traffic concentration, it is suggested that drivers should be calm, wait patiently and actively cooperate with the traffic police. If there is a large flow in and out of the city entrance of each expressway, please follow the following tips:
Harbin-Nantong Expressway enters and exits the city entrance:The peak traffic at the entrance is mainly the traffic in surrounding counties and cities. Due to the large return traffic of Harbin-Datong Expressway, drivers are advised to bypass the national highway G221 (Harbin-Datong Road). There are many refueling vehicles in the service area 26 kilometers from Jiamusi to Harbin, the service area in Pennsylvania and the service area in Yilan, which often lead to the overflow of refueling vehicles, and there are traffic safety hazards.
Tip: Please fill up the vehicle before getting on the expressway. If it is really necessary to refuel on the expressway and the waiting time at the gas station is long, we should take advantage of the policy of no charge at the expressway and drive out of the expressway nearby to find a gas station with few vehicles. The entrance to and exit from the city is Xianfeng Road. In case of heavy traffic, it is recommended to bypass Changjiang Road, Tianheng Street and Xilong Street to enter the urban area.
Harbin south entrance:The entrance and exit is mainly for the collection of traffic flow in the direction of Jingha Expressway and National Highway 102.
Tip: Xuefu Road is the entrance to the city. In case of heavy traffic, it is recommended to bypass Zhengyi Road, Haping Road, Tongjiang South Road and Chaoyang Toll Station to enter the city.
Aha Expressway enters and exits the city gate:The entrance and exit are mainly short-distance vehicles from Acheng to Harbin.
Tip: The sections affected by traffic flow are three major power roads, Tongxiang Street and Jinxiang Street. In case of heavy traffic, you can choose the Third Ring Road to bypass the urban area.
Big Geng home in and out of the city gate:The peak traffic flow at the entrance and exit is mainly vehicles in Daqing and Suihua.
Tip: The increase in traffic volume will increase the traffic pressure at the entrance of Songbei Avenue, Highway Bridge and Zhaojia Toll Station of Heha Expressway around the city. You should drive in a civilized way, wait in line in case of traffic congestion, and obey the instructions of traffic police.
Airport high-speed access to the city gate:The peak traffic flow at the entrance and exit is mainly for vehicles going to and from the airport, and it is expected that the number of vehicles going to the airport will increase in a short time.
Tip: Traffic flows are concentrated in urban and rural roads, viaducts, second ring roads, third ring roads and other roads to Qunli, Songbei and Harbin. You should make good travel preparations in advance and drive safely and civilized.
Keep in mind the traffic safety when driving back ↓
Beware of distracted driving and fatigue driving. Driving in a state of fatigue will lay a big safety hazard, and operations such as making phone calls, playing mobile phones and eating will distract people and make them unable to respond to various emergencies in time. Drivers should ensure enough sleep time, maintain good physical strength and energy, always be alert to fatigue driving, resolutely put an end to distracted driving and try to avoid driving at night.
Cold weather, beware of road icing. During the Spring Festival, there was severe cold weather in Harbin, which resulted in icy and slippery roads, reduced visibility and increased potential safety hazards, which had a great impact on the return trip of people during the Spring Festival. It is suggested that drivers should be prepared for driving on icy roads in advance, especially in some areas around Harbin, which are easy to form microclimate such as fog. They should pay attention to maintaining safe speed and observing the lookout at the same time to effectively ensure driving safety.
Put an end to traffic violations and avoid driving without a license. During holidays, the number of dinners and parties increases, and the risk of drunk driving increases. Drivers should be alert to drunk driving overnight, and do not drive a motor vehicle for a short time after drinking late at night or early in the morning to prevent traffic accidents. At the same time, there must be no serious traffic violations such as license-related, speeding, running red lights, retrograde, etc., to reduce the hidden dangers of traffic accidents.
Standardize the handling of accidents and ensure personal safety. In case of traffic accidents on expressways and national and provincial highways, remember the nine-character aphorism of "pull over, people evacuate, that is, call the police", turn on the danger warning flash in time, and place a triangle warning sign 150 meters away from the direction of coming cars, so that the people on board can quickly move to a safe place to ensure personal safety and prevent secondary accidents.

What are the main contents of RCEP agreement? Understand in one article

  The RCEP agreement consists of a preface, 20 chapters and a four-part commitment table, with a total of 56 annexes, totaling more than 14,000 pages, with a huge content and a wide range of topics. The head of the International Department of the Ministry of Commerce introduced the general situation of RCEP in the fields of goods trade, service investment and other rules.

  (1) Trade in goods

  First, RCEP members have generally achieved a high level of liberalization.After the agreement comes into effect, more than 90% of the goods trade in the region will eventually achieve zero tariff. The main product is to reduce the tax immediately to zero and reduce the tax to zero within 10 years, which is expected to benefit enterprises and consumers in various countries in a short time.

  Judging from the zero tariff level among members.China’s commitment to the 10 ASEAN countries, Australia and New Zealand is about 90%. Except Laos, Cambodia and Myanmar, other ASEAN members, Australia and New Zealand promised me a slightly higher proportion. I promised Japan and South Korea 86% of the final zero-tariff items, while Japan and South Korea promised me 88% and 86% respectively.

  Judging from the specific products that enterprises pay attention to.Take several major ASEAN countries as examples. For example, on the basis of the original China-ASEAN Free Trade Agreement, Indonesia cancelled tariffs on processing aquatic products, cosmetics, plastics, rubber, luggage, clothing, shoes and boots, marble, glass, steel products, engines, televisions, automobiles, spare parts and motorcycles. Malaysia has further opened its market to me for processing aquatic products, cocoa, cotton yarn and fabrics, chemical fiber, stainless steel, some industrial machinery and equipment and parts, automobiles and motorcycles. The Philippines has further granted me zero tariff treatment on pharmaceutical products, plastics and their products, chemical fibers and fabrics, clothing, textiles, shoes, glass and its products, steel products, engine parts, air conditioners, washing machines and other electromechanical products, automobiles and parts. On the basis of the original China-ASEAN Free Trade Agreement, China also opened its market to ASEAN on canned pineapple, pineapple juice, coconut juice, pepper, diesel oil, some chemicals, paper products and some auto parts. If you want to know the specific tax reduction data of each member, you can log on to the free trade zone service network and download the goods concession tables of various countries for inquiry, so that you can intuitively see the tax reduction range and duration of the products concerned.

  Second, another highlight of RCEP in the field of goods trade is the accumulation rule of origin.If RCEP’s commitment to tariff concessions on goods is to plan tax reduction arrangements at the national level, then RCEP’s rules of origin accumulation are a new guide for how to enjoy benefits at the enterprise level. The accumulation of origin is widely known as the most eye-catching achievement in the field of RCEP goods trade.

  According to the rule of origin accumulation, when determining the origin qualification of products, the original materials of other RCEP member countries can be accumulated to meet the origin standard of 40% value-added of final export products, so that it is easier to enjoy preferential tariffs. The specific provisions and practical operation of the relevant rules of origin will be explained in detail by experts from the General Administration of Customs later.

  In a word, the cumulative rule of origin is conducive to further expanding our exports, promoting the trade of intermediate products, and stabilizing and strengthening the regional supply chain, which enterprises must master carefully.

  Thirdly, in terms of goods trade facilitation, RCEP members have also reached a series of high-level rules on customs procedures, inspection and quarantine, and technical standards.With the implementation of these facilitation rules, RCEP will significantly reduce the cost of intra-regional trade, enhance the competitiveness of products in the region, and gradually exert the trade creation effect, bringing more business opportunities to enterprises and more choices and benefits to consumers.

  (B) on trade and investment in services

  Service trade and investment are also the key contents in the RCEP market access field. The openness level of service trade and investment of each member is significantly higher than their respective "10+1" agreements, which significantly improves the liberalization and facilitation level of service trade and investment in the region.

  1. In terms of opening up trade in services,China’s commitment to the opening up of service trade has reached the highest level in the existing free trade agreements. On the basis of about 100 departments promised by China after its accession to the WTO, 22 departments including management consulting, manufacturing R&D and other related services and air transportation have been added, and the commitment level of 37 departments including finance, law, construction and shipping has been improved. Other RCEP member countries also promised to provide greater market access, and some countries also promised to fully open some service sectors. Judging from the service sectors that China focuses on, other parties in RCEP have promised to open up to a greater extent in construction, engineering, tourism, finance, real estate, transportation and other sectors, providing a broad market space for our enterprises to "go global" and expand the layout of regional industrial chains.

  2. In terms of investment,The RCEP Investment Chapter integrates and upgrades the investment rules of the original "ASEAN 10+1 Free Trade Agreement", and makes comprehensive and balanced investment arrangements in terms of investment market access and investment protection, essentially forming the largest investment agreement in Asia, which is conducive to creating a more stable, open and convenient regional investment environment and injecting strong impetus into attracting foreign investment and promoting development in the region.

  In terms of investment market access, all member countries adopt the negative list model to make commitments. For China, this is the first time that we have included the negative list of non-service investment in international agreements, and made high-level liberalization commitments in five areas: manufacturing, agriculture, forestry, fisheries and mining, which greatly expanded the connotation of the list and enhanced the transparency of investment policies. Other parties have also adopted the negative list method to make a higher level of openness commitment. In manufacturing, Japan, Australia and New Zealand are basically fully open except for a few sensitive areas. In agriculture, forestry, fishing and mining, enterprises of member countries are also allowed to enter each other’s markets under certain conditions or requirements. The above arrangement will bring more opportunities to investors from all countries.

  The level of openness promised in the negative list can only be more and more open and cannot be withdrawn. This is a powerful obligation, which greatly improves the certainty of market access, is conducive to enhancing investment confidence in the region, and promotes the integration of upstream and downstream value chains in the region, which is fully in line with the commitment of the CPC Central Committee that "China is opening wider and wider".

  3. With regard to the temporary movement of natural persons,In order to promote all kinds of trade and investment activities, each party promises that investors, internal mobile workers, contract service providers, accompanying spouses and their families from all countries in the region can obtain a certain period of residence and enjoy visa convenience if they meet the conditions. Compared with previous agreements, RCEP extends the scope of application of commitments to all categories of natural persons who may move across borders, and the overall level basically exceeds the commitment level of member countries in existing free trade agreements, with high policy transparency. For a big trading and investment country like China, visa convenience, entry and residence have long been the key concerns of enterprises. The conclusion of the RCEP high-level chapter on the movement of natural persons will open up relevant rules in the region and further provide more policy preferences and certainty for Chinese enterprises to "go global" and "bring in" foreign talents.

  (3) Rules on various fields

  RCEP has expanded the rule fields of many original "10+1" free trade agreements, and included issues such as intellectual property rights, e-commerce, trade remedy, competition and government procurement in benchmarking international high-level free trade rules, and made provisions that meet regional characteristics and needs.

  With regard to intellectual property rights,RCEP covers a wide range of contents such as copyright, trademarks, geographical indications, patents, designs, genetic resources, traditional knowledge and folk literature and art, and has significantly improved the level of regional intellectual property protection while taking into account the different development levels of countries. For example, we revised the Copyright Law through RCEP negotiations, which is in line with the international high-standard rules, so that the court has the right to order the destruction of infringing products and manufacturing materials and tools for infringing products, which is of positive significance for strengthening intellectual property protection and creating a better business environment.With regard to e-commerce,In addition to the provisions on electronic authentication and signature, online consumer protection, online personal information protection, network security and cross-border electronic information transmission, RCEP has also included provisions on data flow and information storage in the FTA for the first time under the premise of complying with Chinese laws and regulations. For example, the agreement stipulates that RCEP members should recognize the legal effect of electronic signature and electronic authentication technology, which makes the signing of online contracts, the authorization of electronic payment and the conclusion of online transactions fully protected and recognized by the agreement, providing an important guarantee for the development and prosperity of e-commerce and digital trade in the region.

  In addition, RCEP includes trade remedy, competition and government procurement.And other specific provisions to ensure fair trade among member countries, oppose market monopoly, protect consumers’ rights and interests, and carry out cooperation in the field of government procurement.

Revealing the Secret: The Truth Behind the Legendary "Great Cause of National Assets Thawing"

  CCTV News:Recently, many people have searched for a phrase on the Internet, "the great cause of unfreezing national assets", which is referred to as the great cause of the nation for short. It sounds like a big project, and it is said that the asset statistics unit of this project is trillion! The source of so much money is also quite mysterious. What is the truth behind the legendary "great cause of thawing national assets"?

  Trillion legacy assets, huge donation farce

  Wang Lirong, a 58-year-old retired female worker in Qiqihar, Heilongjiang Province, claimed to know the inside story of this mysterious wealth. 

111

  Wang Lirong, head of the team of "National Assets Thawing" in Qiqihar City.

  When the royal families of past dynasties retreated, they buried all these assets in the ground or transferred them abroad as the capital for their future revival. During the Republic of China, the four big families buried all these properties. Now this money is already in trillion units.

  Last summer, Wang Lirong received calls from some old people who claimed to be Chen Lifu and others, saying that they were the 17th National Congress officials in charge of guarding trillion-dollar assets. These large sums of money were frozen in dozens of overseas banks. If the old people are nearly 100 years old this year, they plan to unfreeze their assets and give them to people with relatively difficult lives before their death. Later, Wang Lirong received the power of attorney and was appointed as the head of the Northeast Region of the "Chinese National Assets Thawing Committee", which was responsible for convening members to apply for donations. 

111

  The power of attorney says that each applicant can get 1.5 million yuan, and it is also stamped with the official seals of the so-called People’s Republic of China (PRC) the State Council and the Ministry of Finance. Wang Lirong has also received the identity certificates of the so-called guardian assets, certificates of deposits and withdrawals from foreign banks and so on.

111

  Wang Lirong contacted his friend Wang Yun to recruit asset applicants. According to the power of attorney, the money is only given to people with low income or living difficulties such as subsistence allowances, five guarantees and disabilities, and only donated money without charge. Wang Yun not only signed himself up, but also organized hundreds of people. But after waiting for a while, the money was not received. The so-called old man who guarded the assets said that he was guarding the state property and could not move a cent, so they lived in poverty and hoped that everyone would donate some living expenses. 

111

  Wang Lirong convened nearly 400 members of the National Assets Thawing Project, but not all of them were willing to pay the money. At this moment, a leader who claimed to be the Ministry of Civil Affairs called and asked everyone to pay the money, so each person paid 200 yuan.

111

  But then, almost every week, Wang Lirong received a phone call asking for money, and sometimes he had to pay a tax payment certificate, a certificate of source of funds, and so on. He also said that if the number of people paying fees was not enough, he would not get millions of donations. Wang Yun and other "group leaders" made advances when the disabled residents who were found could not afford the money, resulting in heavy debts.

  "Guarding the elderly" disappeared in the mountains, and the police searched across provinces.

  The donations haven’t been sent yet, and the members who have paid many times are anxious. Wang Lirong said that he can’t contact the so-called guardian asset elderly actively, so he can only wait patiently. 

  In March 2016, the members finally waited for the phone calls of several elderly people who guarded the assets. The other party said that they were going to bring 2 billion yuan in cash to Qiqihar City to hold a press conference and distribute it on the spot. On March 24, 2016, hundreds of members of the national assets thawing industry waited for a long time in a square in Qiqihar City, neither waiting for donations nor seeing the elderly who guarded the assets. However, the gathering of hundreds of people attracted the attention of the public security organs.

111

  The police found propaganda documents about "the great cause of thawing national assets" in these backpacks. The police investigation found that the official seals stamped on these documents were all false, and the identity of the person who called Wang Lirong was also false. The so-called Vice Minister Bai of the Ministry of Civil Affairs did not exist. As for the fees collected from the members of "National Assets Thawing Cause", Wang Lirong remitted them to the so-called guardian assets elderly.

  The police found that this was a typical vicious telecom fraud case. The police investigation found that both the fraudulent phone use place and the bank account trading places where the fraudulent money was collected were in Baise, Guangxi.

111

  Qiqihar police rushed to Baise, Guangxi, to collect the surveillance video of the bank being transferred out again, and found that a suspicious middle-aged man entered a deep mountain outside Baise city after handling the transfer business. The police waited at the mountain pass for four days and four nights, and finally arrested five suspects.

111

  The suspect confessed that "China Agricultural Bank National Assets Unfreezing Membership Card" and other materials were printed by computer. The suspect also registered many personal information of the deceived people in the notebook, including more than 2,000 people from Shandong Province, Guizhou Province and other provinces. 

111

  The suspect Long Changzhong confessed that in addition to the five suspects who were arrested, there were others in Guangxi who were engaged in the "great cause of unfreezing national assets" fraud. Before that, they often shared the information of deceived people all over the country. 

111

  Criminal suspect Long Changzhong:

  There are a lot of these people who have been engaged in the "great cause of unfreezing national assets". Some of them have been engaged for decades, and some of them told us that they started to run in 1997.

  Trillion scam is still on, daydreaming is still awake.

  The police investigation found that Wang Lirong did transfer all the money paid by the members to the swindlers, not an accomplice, but also a victim. However, under the condition that the police keep doing ideological education, Wang Lirong is still convinced of the scam.

111

  In the process of solving the case, there were old people who claimed to be Chen Cheng, Huang Jingui and so on, calling Wang Lirong constantly. The police told Wang Lirong that Chen Cheng had died in 1965, so it was impossible to call her, but Wang Lirong still believed in the so-called old man who guarded trillions of wealth. 

  the policeI don’t understand you. What tempts you so much? 

  Wang LirongBecause it’s true, it’s true!

  It’s not a new gadget "Daye" or an old routine.

  According to the police, the "national assets unfreezing scam" appeared about 30 years ago, and the deception methods have been evolving over the years. In recent months, there has even been a unified organization and task deployment. This kind of scam has always grasped the mentality that ordinary people want high returns.

  One of the tricks: high return bait 

1 million, 5 million, 10 million, in the national assets thawing scam, you can get such a large return without paying money, or just paying a little membership fee, which is obviously an impossible bait. 

111

  Deception 2: Pretending to be an authority and forging official documents 

  In every fraud case of national assets thawing, there are many forged government documents or relevant certificates of financial institutions.

111

  The third trick: organized management 

  In the national assets unfreezing scam, the management of swindlers is very organized. In reality, there are general managers, regional leaders, group leaders, and recruited members. Micro-groups are divided into basic membership entry groups with lower fees, followed by project groups with fees as high as several thousand, and even more advanced management groups that can only be entered by group owners and management. These WeChat groups are also divided into registration, finance, publicity and training, flag raisers and other positions. 

111

  Deception 4: the thief shouted to catch the thief.

  With the successful detection of many cases of "national assets thawing" by the police, many fraudulent WeChat groups under the banner of "national assets thawing" are in full swing, and the owners have asked members to change their avatars and nicknames, and they are not allowed to talk to outsiders. Related videos have also been encrypted by publishers.

  There are also some key members of the fraudulent WeChat group who claim in the group that all the people investigated by the police cheat in the name of "the great cause of thawing national assets", and they themselves are the real meritorious personnel of "the great cause of thawing national assets" and are protected. Such a "thief shouted to catch a thief" in an attempt to continue to deceive the victims in the group.

Recently, Sang Mok Park and Michelle A. Visbal-Onufrak of Wilton College of Biomedical Engineering of Purdue University in the United States released a technology in Optica. They have successfully developed an App (mHematology), which can only rely on the smartphone camera to determine the hemoglobin level. The most common clinical laboratory tests can be carried out without blood drawing, which helps to reduce the need for patients to go to outpatient clinics in person, make it easier to monitor critically ill patients, and improve the medical level of low-income and middle-income countries with limited testing laboratories.

02

background introduction

As one of the most common clinical laboratory tests, hemoglobin (Hgb) test is usually used as a preliminary screening for erythropoiesis, so as to check the general health before other specific tests. Spectral analysis is usually used to measure the hemoglobin content of blood because it has a unique light absorption spectrum or fingerprint in the visible wavelength range. However, this type of analysis usually requires huge and expensive optical components, so it is not friendly for patients to deploy this health detection scheme.

The researchers of this project use software to convert the built-in camera of smart phone into hyperspectral imager. Combined with statistical learning technology, this imager can reliably measure hemoglobin level without any hardware modification or accessories, and its mobile application is named MHematography. In addition, the researchers chose the inner eyelid as the sensing site because the microvascular system there is easy to see; It is easy to access and has a relatively uniform red color. The inner eyelid is not affected by skin color, so no personal calibration is needed.

innovation research

The process of hemoglobin measurement using this technology: the patient pulls down the inner eyelid to expose the small blood vessels below. Then, professionals use the smartphone application mHematology to take photos of eyelids (the flash is not aimed directly at the eyeball). Then the spectral super-resolution (SSR) algorithm is used to extract detailed spectral information from RGB photos, and then another algorithm quantifies the hemoglobin content of blood by detecting unique spectral characteristics. Although spectral information is currently extracted by an algorithm on a separate computer, researchers expect that the algorithm can be integrated into mobile applications. In addition, the analysis of multiple linear regression shows that only using RGB data (without the intermediate step of extracting spectral information) may not provide enough information to reliably evaluate the Hgb level in blood.

3.1

Spectral super-resolution (SSR) algorithm

Hyperspectral data in the visible range is mathematically reconstructed from an RGB image (that is, three-color information from R, G and B channels). In other words, it aims to solve the ill-posed problem as an inverse mapping from down-sampled space (three colors) to dense space (multiple wavelengths).

Image source: vol.7, No.6/June 2020/optica (fig.4).

3.2

Quantification of hemoglobin (Hgb) in blood by spectral characteristics

When using a high-resolution spectrum with a large number of wavelengths, we can identify the key potential variables from the spectral intensity, which are responsible for capturing the largest change in the result variable (that is, the blood hemoglobin value). Therefore, this project uses partial least squares regression (PLSR) to transform high-dimensional measured variables into a reduced potential variable space in a way similar to principal component analysis. In order to avoid the possible over-fitting of the prediction model, we determined the optimal number of principal components and verified the spectral blood Hgb prediction model with an independent verification data set.

The owner of the car said that there are so many benefits to choosing the Blue Electric E5 Honor Edition?

In the face of the new energy market that holds high the banner of "lower than oil", the conversion of oil vehicles to electricity seems to have become a major trend, especially in recent years, with the gradual maturity of hybrid technology, owners who were originally worried about the mileage anxiety of pure electric vehicles have also joined the wave of new energy vehicle redemption, further accelerating the process of oil vehicle conversion. And whether "oil-to-electricity" is fragrant or not, let’s see what experienced owners say.

Mr. Zeng (pseudonym) from Guangzhou was one of them. He was originally driving an oil SUV. Although the product quality was good, because he usually used the car more frequently, the cost of using the car was relatively high after a year.Blue Power E5(picture|configuration|inquiry), usually drive the tram when commuting to get off work and traveling by car, and leave the oil truck at home for occasional use as a backup.

At present, Mr. Zeng has driven more than 5,000 kilometers. When talking about the experience of using the car, Mr. Zeng said: "The original car is 1.5T, with turbocharging, it must have sufficient power to climb hills. Yesterday, someone asked, is the blue electric 1.5 without T power enough? After all, our family often needs to climb mountains, but later found that I was overthinking it."

Indeed, there are also many users like Mr. Zeng, who habitually pay attention to the power of the engine when buying a car, but the working principle of hybrid models is completely different from that of fuel vehicles. For example, the Blue Electric E5 Honor Edition has a variety of working modes such as engine, motor and hybrid drive, and whether it is the smoothness of power output, the timing of torque outburst or the subsequent overtaking acceleration experience, etc., the driving texture of plug-in hybrid models is unmatched by fuel vehicles.

Moreover, the blue electric E5 glory version also adopts the Fodi hybrid system produced by BYD, which is more powerful and has higher fuel economy, and the system has been verified by more than 5 million installed units, and the reliability is completely no problem.

Of course, as a plug-in hybrid model, in addition to superior power performance, there is also a high fuel economy and low car cost. Mr. Liao (pseudonym) from Chongqing has a deep understanding of this.

Mr. Liao should be regarded as the first batch of owners of the Blue Electric E5. The previous car was a manual transmission, but I believe that the old drivers in Chongqing know that if you drive a manual transmission, you will encounter traffic jams in the urban area. Moreover, in addition to this, the fuel consumption of fuel vehicles is very high. Mr. Liao said: "Although my 55 is already fuel-efficient, it still costs 6-7 cents a kilometer in the urban area. From the second half of 2021, I plan to change to a hybrid SUV."

According to Mr. Liao’s idea, he wanted to choose a BYD, but later learned that the quality of the BYD E5 is also good, and it uses the same DMI hybrid system of BYD, which is more cost-effective. Therefore, in early April 23, he selected the BYD E5, the top-of-the-line model directly on the model.

When talking about the experience of using the car, Mr. Liao said that the biggest change may be that the fuel consumption is low enough, and the car is really economical. "The previous CS55 fuel consumption was almost 6-7 cents per kilometer in the urban area. Now the blue electric E5 is only more than 30 cents in the middle of the night because it is charged at home, and it is only a few cents per kilometer. It really saves money. Even if you run at high speed, the fuel consumption is similar to my original CS55, which is still acceptable."

The NEDC pure electric cruising range of the Blue Electric E5 Honor Edition is 100km. According to the current travel radius of most cities in China, it is basically possible to commute to and from work purely electric, and users only need to pay for charging costs. Even for long-distance travel, the fuel consumption for feeding is only 5.4L/100km. Compared with most fuel vehicles, the cost of using the car is indeed low.

Many people buy a hybrid car as an economic benefit, but some users buy a hybrid car purely because they can buy enough intelligent safety features at this price, such as Mr. Chen from Hefei.

Unlike other car owners who consider repeatedly choosing an oil car for a tram, Mr. Chen directly and firmly chose the blue electric E5 at the beginning, because he had experienced the Honda of his colleagues before, and the safety configuration in the car was difficult to say until he purchased the blue electric E5. After that, he knew that he only needed about 100,000 price, and he could standard enough intelligent safety configuration.

Sometimes some road conditions are really dark, and the current electric vehicles, bicycles, and pedestrians, no matter who you are, appear on the right side of your car. Whenever there is a light prompt in the left and right rearview mirrors, I will glance at it. When there are street lights, I will find that there are cyclists behind, or there are no running lights.

BluePower E5 Honor Edition is equipped with active safety configuration, including our commonly used blind spot monitoring, parallel assistance, door opening warning, rear collision warning and rear interspersed warning, etc. It is the only SUV with active safety configuration standard in the 100,000 class, which greatly guarantees the safety of users’ daily vehicles. In terms of quality, BluePower E5 Honor Edition also shares the rigorous quality management system of Cyrus, with a total of 100 million kilometers of 0 spontaneous combustion, better safety and more reliable quality.

The conversion of fuel cars to electricity has become a major trend in the industry, and the reasons for users to choose hybrid models are not the same, but whether it is battery life or car cost, in the final analysis, it is more about the quality and price ratio of the vehicle itself. Just like the Blue Electric E5 Honor Edition, at a starting price of less than 100,000, you can enjoy the driving experience of a medium-sized plug-in SUV. Compared with the original version, the price reduction does not reduce the distribution. Even the entry-level version has the same pure electric cruising range and active safety configuration as the high-end version, which fully reflects the degree of care of car companies for users.

Venice Film Festival Observation: Is it reliable for musicians to be the chairman of the jury?

    Alberto Barbera, president of Venice Film Festival, commented on this musician: "Alexander is not only one of the greatest contemporary film composers, but also an enthusiastic fan. He has excellent artistic sensitivity and rich knowledge of film, film history and film language." Alexandre desplat, who has been nominated for six Oscars, has composed scores for hundreds of films, and is the most valuable successor among the French film score masters. In the 21st century, few composers have composed music for so many excellent films and created such energetic and unforgettable music.

Zhejiang Propaganda | It’s time to disperse the "class flavor"

  "The high-speed rail and subway are full of class flavor", "class flavor" can’t be hidden at all "and" stained with class flavor, I can’t go away in my life "… The word" class flavor "has deeply resonated with many young netizens.

  The so-called "class smell" is, to put it bluntly, a sense of fatigue that cannot be dissipated after work. Many netizens also took a self-portrait comparison picture of "before work VS after work": energetic before going to work and withered after going to work. In sharp contrast, the dissipation of "class flavor" has become a "just need" among many young people.

  Then, why does "class flavor" become a widely discussed social phenomenon? How should this thick "class flavor" dissipate?

  What is the smell of "class flavor"? From ordinary netizens who simply spit out their physical and mental exhaustion after going to work to medical bloggers who began to demonstrate the scientific basis of "class flavor" from a professional point of view, they came to conclusions such as "inflammatory physique" and described it in various ways online.

  Some netizens also summarized the "class taste" of all walks of life. For example, people in the media have the media flavor of "we won’t have a holiday until the universe explodes", "teachers" have the taste of "being a teacher for everyone", and doctors have the taste of "needing to see a doctor anytime and anywhere" … In fact, "class flavor" is not a natural derogatory term, but a trace left on everyone by work, which is objective. What everyone is teasing now is that the "class flavor" is too strong.

  The definition of "class flavor" in many viewpoints is inseparable from the following key words: "physical exhaustion", high-intensity work and commuting, which leads to a lot of energy consumption, which is the most direct factor that makes people contaminated with "class flavor". "Spiritual internal friction", the negative emotions brought by work affect the mood, which makes people tired, but there is nowhere to hide. "Choice anxiety", "I want to leave my job every day, but I’m in Man Qin every month", some people complain anyway, but in the end I still have to "bend my back for the bucket of rice".

  The "class flavor" that can’t be removed has made many young people change their living habits and formed many "famous scenes" on the Internet. For example, dressing up at work deliberately, dressing casually, dressing up after work and living a refined life; I’m grumpy and miserable at work, and I’m dull and empty after work.

  From the anticipation of entering the workplace, to getting used to the pace of going to work, I feel that the road ahead is long, and then I feel job burnout after working for a long time, but I still have to grit my teeth in the face of the burden of making money to support myself … These conditions are actually a true portrayal of some migrant workers at different stages, with different "class tastes" at different stages, but the same is "concentration exceeding the standard".

  two

  Going to work is a way to get paid according to work and improve self-worth. Why has it become the source of "class flavor"? The discussion on "class flavor" in the network actually reflects some problems existing in the current workplace. The author believes that there are three main aspects:

  For example, the imbalance caused by gradual involution. Many migrant workers on the Internet will be exposed to such a scene: after working overtime, they should have gone to bed before 11 o’clock in the evening after washing, but they always feel that the whole day is occupied by work, so they are very unwilling, so they have started "retaliatory staying up late" in bed. As a result, not only did the spirit not relax, but also the body did not get a rest. The next day, I stepped on the work with a tired body, which led to poor state and low efficiency. So repeated, gradually forming a vicious circle. This kind of imbalance between the pace of life and the pace of work will always plunge into the hearts of migrant workers from time to time, making it difficult for migrant workers to "taste the class".

  Such as the invasion of bad workplace culture. In the workplace, it is not uncommon to "whip the fast cow" and "small horse-drawn cart", and "those who can work harder" becomes "those who can work harder", and sometimes "those who can work in vain" eventually leads to "those who can complain more". Under the interference of some unhealthy workplace cultures, a few companies have formed a bad atmosphere of "being competent is better than being able to speak, and being able to work is better than being able to pack", which is consuming the enthusiasm of many young people. On the one hand, we have to cope with unreasonable work arrangements, and we have to work all the time if we can, and we are pressured by various tasks; On the other hand, we have to face the PUA of individual leaders and various false promises. The resulting physical and psychological pressure makes it difficult to get rid of it even after work.

  For example, the internal friction of the collision between ideal and reality. In the workplace, ideals and reality often collide. Especially when the work content is quite different from your own imagination, or you have to choose a job you don’t like in order to make a living, the fullness of your ideal will increasingly set off the sense of reality, and disappointment with the workplace and dissatisfaction with the present will always be pulled repeatedly in your heart. A small number of young people who have just left campus have mental internal friction because they can’t overcome the gap between reality, unhappiness at work and unhappiness in life.

  three

  Why is it difficult to eliminate the fatigue caused by "class taste"? This is also a question that many people are asking. It is not that young people want to lie flat or be lazy, but that everyone has a simple desire: they hope that the boundaries between work and life can be relatively clear.

  How to solve the "class taste" is not only a personal problem of young people complaining about "class taste" on the Internet, but also a social problem related to the happiness of thousands of families. Creating a healthy workplace environment is also related to social development. The author has three sentences about this.

  After complaining, learn to reconcile. It is a way for many young people to relieve their emotions by tapping the keyboard on the Internet to complain about "class taste". For this phenomenon, all sectors of society may wish to be tolerant. After complaining, young people can also try to improve their happiness in life and cure themselves by discovering the beauty in life.

  For example, leave the serious working environment and have a Citywalk; in the beautiful scenery; Prepare a delicious meal or take a hot bath for yourself after returning home, so that the "cutting" between work and life has a sense of ceremony, and so on. In life, it is an effective way to relax the body and mind by learning to "take the pressure lightly" brought by work.

  Smooth out the inner volume and reach a consensus. For many people, "class flavor" is all rolled out. This kind of volume is often meaningless and low-dimensional inner volume. Going to work should not be a derogatory term, but in the face of all kinds of inefficient and repetitive work, people may have the idea of wanting to escape for a short time. A few employers are used to treating employees’ busy appearance as achievements, showing off-track development with internal friction and being complacent about it.

  In fact, this kind of "hard work" and "development" that is a mere formality brings about a "lose-lose" between employers and employees. In order to achieve "win-win", all parties still need to form a consensus. Especially for the former, reducing invalid involution and strengthening humanistic care are workplace cultures that need to be continuously advocated.

  Workplace management should be more "intentional". "Class taste" is not simply "complaining about being tired", but more often it is the self-mockery of people in the workplace who are having fun in hardships. However, self-mockery belongs to self-mockery. Both enterprises and government departments should create a good working environment, take the holidays, get off work and make up the subsidies.

  I believe that if the legitimate rights and interests of migrant workers can be safeguarded, the "class flavor" will certainly be able to get rid of. Only by using sincere and caring management mode and treating migrant workers as important partners can they get rid of "cold air" and find the meaning of work.

  "Class flavor" is annoying, but work is an unavoidable part of life. To cope with pressure, we should have a normal mind and employers should pay more attention to it. In this way, the strong "class flavor" is expected to gradually dissipate.


【 Figure 】 mythbusters (7) Can’t use a wiper when an egg is attacked?

[Car Guide] I believe many people have heard of a rumor on the Internet: robbers frequently attack the windshield with raw eggs in a certain place, and never turn on the wiper to spray water. Because the egg will solidify when it meets the glass water, blocking the view up to 90%. When you are forced to stop to clean the glass, the robbers take the opportunity to rob. A search on the internet shows that there are more than one million similar rumors.

When I first heard the news, I couldn’t help but feel a little scared. Nowadays, there are so many kinds of robbers’ tricks that it is impossible to prevent them. After many years, similar rumors do not seem to have subsided. Although there have been rumors in the meantime, they are still used to reporting that they would rather believe their mentality and be more careful. It’s the end of the year again, and it’s inevitable for everyone to visit relatives and friends and travel by car, and the old-fashioned safety issue has been tirelessly hung up. Today, we will solve the rumors and doubts for everyone through experiments.


Experimental introduction

Experimental tools:N raw eggs, some of which are added with "mysterious substances"

Experimental environment:The outdoor temperature is 3 degrees Celsius, and the test vehicle travels at a speed of 20 km/h.

Experimental process:The effects of raw eggs smashing windows and adding mysterious substances during the day were tested in two environments: day and night.

Before the experiment, we should check the working conditions of wiper blade and glass water to ensure the normal function of the vehicle system.


Experiment 1: Ordinary raw eggs

We drove at a speed of about 20km/h, and the eggs quickly broke open after touching the windshield. At this time, we turned on the water spray and wiper, and a large area of egg debris was cleaned up, and there was no obvious trace after repeated times.

Experiment 2: Ordinary raw eggs stay for a while before cleaning.

According to the rumors in the network, we didn’t rush to clean the eggs after they were smashed, but continued to drive for a minute or two before turning on the wiper. Because the egg white part has solidified, although the cleaning seems to have a good effect, the glass still leaves obvious white marks after drying, which affects the line of sight.

Experimental summary: if you really encounter an egg attack, you can wash it immediately!


Experiment 3: Night Effect of Common Eggs

We simulated the first experiment again in the case of poor night line. Although it can achieve a cleaner effect after several times of cleaning, due to the poor night light itself, the inconspicuous residue will also have a great impact on the line of sight.

Experiment 4: Ordinary Raw Eggs+Mysterious Formula

There are also rumors on the Internet that people who smash eggs will put some substances in the eggs before they implement "work". We also conducted related experiments to find a "mysterious formula", which seems to have achieved the legendary effect on the Internet.

We also drove the vehicle at the speed of 20km/h, and the eggs smashed by the roadside were broken on the windshield. After turning on the wiper, most of the egg residues were removed, but some mysterious residues were still not completely removed. After several attempts, the effect was still not obvious.

Test summary:Although eggs with mysterious substances can’t be wiped clean by the wiper very well, it’s better than not. Therefore, to sum up, if you encounter egg information, you should clean it with a wiper in time to improve your sight.

The following is a video of the effect of using a wiper after an egg attacks the window during the day and in the dark.

Why doesn’t the 29-year-old mayor face up to the online questioning?

  This is no longer an era when officials can override everything and settle all disputes with one hand. The Internet era is an era of democracy. Officials’ words, deeds and behaviors are already under the supervision and comment of the network-they are supervised by the trend and welcomed by netizens; If you don’t want to be supervised against the trend, you will be forced to strip off your clothes by the torrent of the internet and human flesh search. Digging deep into the ground, human flesh search and network supervision are a great test for cadres. It is like a microscope, more like a touchstone. The problem information is easily detected by keen netizens, and officials should stand up to the most demanding examination and supervision of the network. Editor of this issue: Zhang Tuoya
