foreword

It has been more than three years since the outbreak of the COVID-19 epidemic; It has been two years since the establishment of the National CDC in May 2021.

Before May, there was little news about the establishment and promotion of provincial disease control bureaus, and the overall work progress was very slow. However, in May this year, especially in the recent period, under the pressure and urging of the relevant state departments, many provinces put up the brands of the disease prevention and control bureaus of their respective provinces, autonomous regions and municipalities directly under the Central Government before the deadline.

This series of actions and information gives us the feeling that "the brand should be hung out first, and the requirements of this time node should be completed before deadline. As for the three-set plan, internal organization, specific work and other contents, let’s wait for the next node to talk about it slowly. As for the reform of the disease control system, who knows?"

挂个牌子也许是疾控局成立，或者说疾控体系改革最简单的内容了，可是然后呢？疾控体系改革就结束了？疾控体系改革就这些吗？

当然不是，疾控体系改革任重道远，道阻且长，目前疾控体系改革尚没有看到太多的实质性进展，疾控局的成立只是个开始。

疾控体系改革必须以解决其存在的4个主要问题——能力不强、机制不活、动力不足、防治不紧密为导向。这是一个艰难的过程，我们只能在不断的探索和实践中寻找最适合我们的那条疾病预防控制的健康之路。

01、国家疾控局成立过程 　

我们首先把时间拨回新冠疫情发生后的第一个全国两会，2020年全国两会。

2020年5月24日下午，中共中央总书记、国家主席、中央军委主席最高领袖在参加十三届全国人大三次会议湖北代表团审议时强调，防范化解重大疫情和突发公共卫生风险，事关国家安全和发展，事关社会政治大局稳定。要坚持整体谋划、系统重塑、全面提升，改革疾病预防控制体系，提升疫情监测预警和应急响应能力，健全重大疫情救治体系，完善公共卫生应急法律法规，深入开展爱国卫生运动，着力从体制机制层面理顺关系、强化责任。

In the context of the COVID-19 epidemic, on April 28th, 2021, the State Council appointed and dismissed national staff, and appointed Wang Hesheng, deputy director of the National Health and Wellness Commission, as the director of the National Bureau of Disease Control and Prevention. Subsequently, the National CDC was established, and it took nearly a year before the "three-set plan" of the National CDC was released.

Established by listing:On May 13th, 2021, the National Bureau for Disease Control and Prevention was officially listed, which belongs to the deputy ministerial level managed by National Health Commission. It will be responsible for formulating policies for the prevention and control of infectious diseases and public health supervision, guiding the construction of disease prevention and control system, planning and guiding the construction of epidemic monitoring and early warning system, guiding the construction of scientific research system for disease control, public health supervision and management, and supervision of infectious diseases, which means that the functions of disease control institutions have changed from simply preventing and controlling diseases to comprehensively maintaining and promoting the health of the whole population.

The "three-set plan" was announced:On February 16th, 2022, China Organization Network published the Provisions on the Functional Allocation, Internal Structure and Staffing of the National Bureau for Disease Control and Prevention and the Notice of the General Office of the State Council, the General Office of the Central Committee of the CPC on Adjusting the Functional Allocation, Internal Structure and Staffing of the National Health and Wellness Committee on February 16th, making it clear that the National Bureau for Disease Control and Prevention is a national bureau under the management of the National Health and Wellness Committee and is a vice-ministerial unit. At the same time, it stipulates the function allocation, internal structure and staffing of the National Bureau for Disease Control and Prevention, and adjusts the internal structure of the National Health and Wellness Committee.

It only took more than three months for the national medical insurance bureau to go from listing to "three decisions"And in the "transition period" of more than three months, we also made high-profile actions: centralized collection of anticancer drugs and medical insurance access negotiations, management of medicines and medical behaviors, and investigation of management of high-value medical consumables, which frequently caused waves in the industry, and we can’t wait for the announcement of the three-set plan to start the reform process.

The overall progress of the National CDC is in sharp contrast with it:It has been nearly nine months since the listing of the National CDC to the announcement of the final plan, and in these nine months, except for the addition of a deputy director, there is almost no official action of any institution.

02、Establishment process of provincial disease control bureaus 　

At the beginning of the establishment of the National Bureau of Disease Control and Prevention, Fujian Province took the lead in announcing the overall framework for the establishment of provincial, municipal and county disease control bureaus: "Systematically promote the reform of the province’s disease control and prevention system; Establish a provincial-level disease prevention and control bureau, and set up municipal and county-level disease prevention and control bureaus based on the health and health departments at the same level. " In August 2021, Fujian Provincial Bureau of Disease Control and Prevention (to be established) was unveiled in Fuzhou.

In addition, there was almost no progress in the provinces. Until this May, due to various factors, the "deadline" was finally determined.The provincial disease control bureaus are required to complete the listing before the end of May.. Ever since, almost every day, provinces have announced the listing of CDC, and the listing of CDC in various places has accelerated.

It is expected that at the request of relevant departments, the "three-set plan" of the disease control bureaus in cities, counties and districts throughout the province and the disease control bureaus may also be set within 2 months.

03、The ideas and responsibilities of setting up the CDC have been basically clear. 　

Country:The National Bureau for Disease Control and Prevention was established. The National Bureau for Disease Control and Prevention is a national bureau managed by the National Health and Wellness Committee, with 170 administrative staff at the deputy ministerial level. There are 1 director, 4 deputy directors and 32 deputy directors. There are 10 departments, including comprehensive department, planning, finance and regulation department, monitoring and early warning department, emergency response department, infectious disease prevention and control department, health and immunization planning department, comprehensive supervision department I, comprehensive supervision department II, science, technology, education and international cooperation department (Hong Kong, Macao and Taiwan office) and government party committee (personnel department).

Provincial level:According to the central model, the provincial CDC is established, which is generally the deputy department level with different offices, and the director of the CDC is also the deputy director of the Health and Health Commission.

Cities and counties:Under normal circumstances, there is a CDC in the Health and Health Commission, and the director of the CDC is also the deputy director of the Health and Health Commission at the same level.

From the perspective of responsibilities, the main responsibilities of the provincial CDC include:To organize the formulation of draft regulations, policies, plans and standards for the prevention and control of infectious diseases and public health supervision; Leading the professional work of disease control institutions at all levels in the province, organizing the implementation of the national immunization program, overall planning and supervising the disease control work of infectious disease medical institutions and other medical institutions; Planning and guiding the construction of an epidemic monitoring and early warning system for infectious diseases, and being responsible for the work related to the epidemic response of infectious diseases; Cooperate to guide the construction of scientific research system for disease control; Responsible for the prevention and control of infectious diseases, environmental sanitation, school sanitation, public place sanitation, drinking water sanitation supervision and management, occupational hygiene and radiation hygiene supervision.

Judging from the public information, the positions of "chief officers" of provincial CDC can be roughly divided into two categories:In some areas, the former responsible comrades of the Provincial Center for Disease Control and Prevention were promoted to the director of the Bureau of Disease Control and entered the party group of the Provincial Health and Wellness Committee, and in some areas, the responsible comrades of the Provincial Health and Wellness Committee who were in charge of disease control and prevention were held.

04、There is not much substantial progress in the reform of disease control system. 　

At least for now, there is no substantial progress in the reform of the disease control system.

The listing of CDC has little to do with the main problems of China’s centers for disease control and prevention at present. The establishment of CDC is to sort out the disease prevention and control system to a greater extent, or even to reorganize and adjust the functions within the health care system.There is still a lot of room for efforts to meet the requirements of "persisting in overall planning, reshaping the system, comprehensively improving and reforming the disease prevention and control system".

However, the establishment of the CDC can be regarded as the beginning of the reform of the CDC system. Straightening out the system and mechanism, clarifying the functional orientation, speeding up the reform of the CDC institutions at the provincial, municipal and county levels, solving the main problems existing in the CDC system, and speeding up the improvement of the CDC system have become the next key tasks and tasks put forward by all localities.

At the same time, we can also see that even if there is not much substantive content, it is more about the adjustment and adequacy of departmental functions. The establishment process of the National CDC and local CDC has been slow and difficult, and the reform of the entire CDC system can be imagined.

05、Four key issues in the reform of disease control system 　

Many people inside and outside the industry have said that China’s disease control system has problems such as low treatment and serious brain drain, but in the final analysis,At present, there are four main problems in the prevention and control system of physical diseases in China: weak ability, inflexible mechanism, insufficient motivation and loose prevention and control.

Therefore, in order to make substantial progress in the reform of disease control system, we must start with these four main problems.

1, the ability is not strong

Question:

The ability is not strong, and we don’t have to admit that the ability of disease control system is not strong, especially in some districts and counties, the overall ability is generally not strong, and the personal ability is generally weak.

Because of insufficient preparation or because of the positioning and treatment of grassroots disease control, it is impossible to recruit highly educated talents, resulting in fewer grassroots disease control personnel and fewer professional business personnel, which leads to poor overall ability. Secondly, from the perspective of personal ability, many people’s business ability is also relatively general. A CDC with strong ability is often one or two people, and then more tasks can only be pressed on the shoulders of these two people, resulting inCapable people are busier and don’t get much, and those who can’t are more idle and more chaotic..

Ideas:

The disease control system should have a set of assessment and evaluation mechanism in line with its own reality, which must be operable, and then be assessed regularly. Of course, it needs to be clear,This assessment is not only for the staff of the CDC, but also for every link of the CDC system.From the staff of community health service centers to the staff of medical institutions who are responsible for the online reporting of infectious diseases and the corresponding responsibilities of public health, from the staff of CDC to the staff of CDC, the staff of CDC should be assessed accordingly.

The assessment content should include the completion of the government’s public health functions and public welfare tasks undertaken by disease control institutions at all levels, the completion of the guidance and supervision tasks undertaken by regional medical institutions, and the improvement of residents’ health indicators in the jurisdiction. At the same time, it is necessary to strengthen the application of assessment results, and take the assessment results as an important basis for the appointment and dismissal of personnel, the evaluation of the first, the total salary and the approval of reward performance in CDC, and link them with the performance, further study and promotion of CDC staff.

All of the above, if gradually promoted and formed a set of practical things, will be very effective for the improvement of the overall system capacity, of course, this process is very difficult.

2, the mechanism is not alive

Question:

Because the disease control system is a part of the system to a large extent, this leads to many restrictions, unlike companies in a market economy, which are flexible and efficient.

Ideas:

First of all, it needs to be explained that the disease control system will never completely become a company under the market economy, which is determined by its nature. However, it is still possible to learn from each other’s strengths, and the purpose is to make the development of disease control system, especially human resources for disease control, become living water.

As implemented in some areasThe system of "chief public health expert" is a good example.The system of "chief public health experts" can be implemented for disease control at least above the municipal level, and the chief public health experts of epidemic disease, exemption from regulations, virus and disinfection are selected in a scientific and reasonable way. This is one of the measures to strengthen the construction of public health talents, provide talent guarantee for the construction of public health system, set up "chief experts" for disease control based on scientific research, talents and foreign exchanges, and build "hard power" for disease control personnel.

On March 31st, at the provincial conference on disease prevention and control system in 2023, Hao Yibin, director of Henan CDC, said:

At present, the Center for Disease Control and Prevention of Henan Province is setting up a chief expert system, which encourages senior experts with rich experience in scientific research and business management to be full-time "chief public health experts" by enjoying favorable conditions such as retaining the original administrative post treatment and special retirement and re-employment policy, empowering inter-departmental scientific research teams and providing sufficient scientific research funds.

In addition, should be established.Practice-oriented evaluation mechanism of public health talents, the implementation of classified assessment. Promote and strengthen the cooperation between disease control institutions at all levels and the college of public health in personnel training, personnel mutual employment, platform co-construction, data sharing, etc., create a demonstration base for public health personnel training in cooperation between schools and localities, and jointly cultivate applied professionals in public health.

At the same time, we should also increase the decision-making power of disease control institutions at all levels, reform the evaluation criteria of professional titles, and reasonably increase the proportion of middle and senior positions in disease control institutions. Improve the system of public health doctors, cultivate and expand the team of public health doctors, and explore giving public health doctors the right to prescribe.

3. Lack of motivation:

Question:

To put it bluntly, the disease control system is too poor and the income is too low. This is the root of many problems, because the income is low, so we can’t attract talents and can’t keep talents, so our ability is not strong; Because of the low income, more work and less work, they gradually began to muddle along and began to make no progress.

Ideas:

Tianjin CDC, Wuhan CDC, etc. have publicized the foreign services that they can charge for. For example, Tianjin CDC has launched 72 foreign technical services, which can provide a variety of health services for individuals and families, and provide entrusted testing services (23) and public health technical services (49) for the government and relevant departments, enterprises and institutions, and social organizations.

The project specifically includes the detection of water, air, food, etc.Communication and defense officeIt can provide technical support and policy consultation related to infectious disease prevention and control, theme planning activities of health science popularization day related to infectious disease prevention and control, and production of health science popularization videos.Exemption officeCan provide vaccination related policy advice and technical support, vaccination knowledge training. All these provide ideas for other disease control institutions.

The reform of disease control should explore and promote the "first-class security and second-class management" and implement it in detail.Two permits",allowing disease control institutions to break through the current wage control level of public institutions, allowing medical and health technical services to be provided on the basis of completing the approved tasks, and further stimulating the endogenous motivation of disease control institutions. While implementing the policy of full financial security, we should establish a new operating mechanism that combines security with incentives and conforms to the characteristics of disease control institutions, give them internal distribution autonomy and stimulate their operational vitality.

4, prevention and control is not close

Question:

To tell the truth, this is the most difficult to solve. Even after the establishment of the CDC, the separation between prevention and treatment may be more serious.This seems to be seen from the monitoring of the new crown infection virus.

Ideas:

For disease prevention and control, if prevention and control are to be closer,It is necessary to make clear the responsibilities that all kinds of medical institutions and medical administration departments at all levels should and must undertake in disease prevention and control.At the same time, the mechanism of personnel communication, information communication, resources communication and supervision and supervision is also established between disease control and medical care, and the disease control work is promoted to be included in the performance appraisal content of medical and health institutions.

In addition, it is necessary to establish an innovative supervision, assessment and evaluation mechanism for disease control institutions to medical institutions, and explore the establishment of a full-time and part-time disease control supervisor system in medical and health institutions to supervise the development of disease prevention and control, and urge the implementation of reporting responsibilities for infectious diseases and public health emergencies. For example, whether the infected cases in COVID-19 were reported realistically, such as whether fever of unknown origin was reported in time.

The reform of disease control system has a long way to go, and all key measures of reform and development must be supported by governments at all levels and relevant departments before they can take effect.

Everything has just begun, and China’s disease control system needs to focus on the long-term, overall planning, layout of the future, and embark on a road of public health governance with China characteristics.

　　CCTV News:According to the website of the Central Meteorological Observatory, the Central Meteorological Observatory issued a typhoon red warning at 10: 00 on July 26th: the center of Typhoon DOKSURI (super typhoon level) No.5 this year was located at 8: 00 a.m. on the 26th in the south of bashi channel, about 350 kilometers south of Taiwan Province, China, which was 18.8 degrees north latitude and 121.3 degrees east longitude, and the maximum wind force near the center was 17 (58. The lowest air pressure in the center is 925 hectopascals, the radius of the seventh-level wind circle is 300-450 kilometers, the radius of the tenth-level wind circle is 120-180 kilometers, and the radius of the twelfth-level wind circle is 90-120 kilometers.

　　It is estimated that Du Surui will move to the northwest at a speed of 10-15 kilometers per hour, with little change in intensity. It will move into the northeastern part of the South China Sea from the night of 26th to the morning of 27th, and then gradually approach the coastal areas from Fuqing, Fujian to Huilai, Guangdong, and will land in the above coastal areas from the morning of 28th to the morning, with the maximum possibility of landing in Jinjiang, Fujian to the coastal areas at the junction of Fujian and Guangdong (strong typhoon level, 42-48m/s, 14-).

　　Gale forecast:From 14: 00 on the 26th to 14: 00 on the 27th, there will be 6-8 winds and 9-10 gusts in bashi channel, the east of Taiwan Province, the northeastern and southern seas of the South China Sea, the Taiwan Province Strait, the southern part of the East China Sea, Taiwan Province Island and its coastal areas and Fujian coastal areas. Among them, the winds in bashi channel, the waters east of the northeastern South China Sea, the waters south of the Taiwan Province Strait and the southern coastal areas of Taiwan Province Island can reach 9-12 and the gusts are 13-15.

　　Precipitation forecast:From 14: 00 on the 26th to 14: 00 on the 27th, there were heavy rainstorms in parts of eastern Zhejiang and Taiwan Province Island, among which there were heavy rainstorms (100-150 mm) in parts of southeastern coastal areas of Zhejiang and heavy rainstorms (250-400 mm) in parts of eastern and southern Taiwan Province Island.

　　Defense guide:

　　1. The government and relevant departments shall, in accordance with their duties, do a good job in typhoon prevention and emergency rescue.

　　2. Water operations and passing ships in relevant waters should return to Hong Kong to take shelter from the wind, strengthen port facilities, and prevent ships from anchoring, grounding and collision.

　　3. Stop large-scale indoor and outdoor gatherings and dangerous outdoor operations such as high altitude.

　　4. Reinforce or dismantle structures that are easy to be blown by the wind. Personnel should not go out at will. They should stay in windproof and safe places as far as possible, so as to ensure that the elderly and children stay in the safest place at home, and the dangerous people will be transferred in time. When the typhoon center passes by, the wind will decrease or stay still for a period of time. Remember that the strong wind will suddenly blow, and you should continue to stay in a safe place to avoid the wind, and the dangerous people will be transferred in time.

　　5. Relevant areas should pay attention to prevent flash floods and geological disasters that may be caused by heavy precipitation.

On the 14th, the United States released the results of the four-year review of China’s imposition of tariff 301, announcing that on the basis of the original tariff 301, it would further impose tariffs on electric vehicles, lithium batteries, photovoltaic cells and other products imported from China.

After the news came out, many business people and business groups in the United States expressed their dissatisfaction.

In a statement to CBN, u.s.-china business council, a group of 270 American companies doing business in China, expressed disappointment with the results of the four-year Section 301 investigation announced by the Office of the US Trade Representative (USTR).

USCBC said: "We are disappointed with this result, because maintaining the previous tariffs (without lowering them) and imposing additional tariffs will eventually make it more difficult for American companies to compete at home and abroad. This will lead to fewer jobs in the United States. In the context of continued inflationary pressures, this will also raise the US consumer price index. "

Earlier, China’s Foreign Ministry spokesperson Wang Wenbin said at a regular press conference on the 15th that according to Moody’s company’s calculation, American consumers bear 92% of the cost of levying tariffs on China, and American families increase their expenses by $1,300 a year.

Liu Bin, a researcher at university of international business and economics School of Government Administration and China World Trade Organization Research Institute, said in an interview with China Business News that (compared with Trump’s tariffs on China), we can see that the industries and products subject to tariff increase are relatively concentrated, and the tariff collection quota has been greatly adjusted. For emerging industries, especially new energy vehicles, the United States has a strong intention to restrict or restrict development.

American consumers pay the bill?

On 14th, KenGriffin, American billionaire and founder of Citadel, said at a forum in Qatar: "Imposing high tariffs on China electric vehicles with low price and high quality, which are beneficial to American consumers, is another manifestation of the discontinuity of Biden’s economic strategy."

The National Retail Federation (NRF) is also "very disappointed" with the Biden administration’s move, and said that "as consumers continue to fight inflation, the last thing the (US) government should do is to impose additional taxes on imported products, which will be paid by American importers and ultimately American consumers".

Recently, Goldman Sachs said in a report that "tariffs in 2018-2019 have significantly increased consumer prices" and that these price increases were "almost entirely borne by American enterprises and families", not China exporters.

Goldman Sachs estimates that every one percentage point increase in the effective tariff rate will directly reduce the gross domestic product (GDP) of the United States by 0.03%, increase consumer prices by 0.1% and keep inflation rising for one year.

Sweet, chief American economist at Oxford Economic Research Institute, said that the political significance of tariffs is usually greater than the economic significance.

Sweet said: "Most economists think that tariffs are a bad idea, because tariffs will hinder a country from benefiting from specialization, disrupt the flow of goods and services, and lead to improper allocation of resources. When implementing tariffs, consumers and producers often have to pay higher prices. "

The new york Federal Reserve also found that tariffs in 2018 cost American families $419 a year due to increased tax burden and loss of market efficiency. The researchers estimate that this figure has doubled as other tariffs take effect in 2019.

Economists wrote in a working paper published by the National Bureau of Economic Research in January 2024 that the net economic impact of import tariffs, retaliatory tariffs and agricultural subsidies on American employment and enterprises is "at best ‘ Rinse ’ Look, and it may be a slight negative impact. "

The above-mentioned researchers said in this working paper that trade friction does seem to bring political benefits and strengthen the support of the Republican Party in the heartland of the United States and the communities most affected by tariffs. "Residents in areas protected by tariffs are unlikely to identify themselves as Democrats, and they are more likely to vote for Trump. Therefore, despite the high economic cost of tariff protection, voters seem to have given a strong response. "

American industry demands competition.

Recently, U.S. Treasury Secretary Yellen frequently appeared in the media to explain the tariff increase policy, but during the interview, she also repeatedly faced questions about whether the tariff increase would drive up prices, including "China’s electric cars are cheaper, so if more people (in the United States) buy them, wouldn’t it help solve the climate change problem".

In this regard, Yellen explained that with the accumulation of experience in producing these products by American companies and the development of newly built battery factories in the central and western regions, the price of automobiles will drop.

However, I am afraid that the industry has different views. CarlosTavares, CEO of Stellantis, a global automobile manufacturer, said that raising tariffs would not protect his company. He believes that "the only choice is to continue fighting", so the only way to compete fairly is to reduce costs and provide electric vehicles at more affordable prices.

In fact, there have been many cases before that prove that imposing high tariffs cannot promote the development of domestic enterprises in the United States.

In 2002, the United States imposed tariffs on imported steel and aluminum products. Subsequent studies showed that although this only caused economic losses of about $30 million, it led to an increase in the price of the steel consumption industry in the United States, and led to a sharp decline in employment opportunities in the entire steel industry, especially those small enterprises that did not have market power to influence prices.

In 2009, the United States imposed tariffs on tires imported from China. The Peterson Institute for International Economics found that this move was thought to have saved about 1,200 jobs in the tire manufacturing industry in the United States, but it cost Americans $1.1 billion in the form of rising prices.

A veteran who has been engaged in the import and export industry in the United States for a long time told the First Financial Reporter that in his view, the United States’ practice of adjusting tariffs this time is more posturing than actual impact.

Taking the solar panel products he is very familiar with as an example, he told reporters that before this adjustment, the solar panels imported by the United States from China had been greatly reduced due to anti-dumping duties: most of the solar panels on the American market were imported from Viet Nam or Thailand, and very few were directly imported from China. In fact, since last year, thousands of containers of related enterprises in China have been detained at the American terminal, and related enterprises may have paid millions of dollars in yard fees at the terminal. The current policy of the United States clearly shows that in order to enter the American market, these companies must set up factories in the United States.

However, in view of some cases that have happened, the prospect of setting up factories in the United States is not optimistic. "If the United States does block the import channels from Vietnam, I can’t imagine where American solar panels will be imported. But it seems unrealistic to rely on solar panels produced locally in the United States. " He added that many media in the United States have also questioned this, and they don’t understand why the import of clean energy products from China should be prevented, especially in the context that the US government has been advocating these clean energy technologies.

Cui Fan, a professor in the Department of International Trade of university of international business and economics Institute of International Economics and Trade, also told China Business News that Biden’s government has begun to contain the overseas investment of China Photovoltaic.

He explained that on April 24, the United States began the photovoltaic double-reverse investigation procedure for Vietnam, Cambodia, Malaysia and Thailand. It is expected that the preliminary ruling will be made this year and the final ruling will be made in the middle of next year. At present, the dumping margin of the four countries listed in the application for investigation ranges from 70.35% to 271.45%, which once blocked the photovoltaic exports of the four countries to the United States.

What needs to be noted is that after the United States announced the imposition of tariffs on China, the EU side, which is conducting countervailing investigations on China’s electric vehicles, is more cautious.

In an interview with China Business News, Liu Bin said that the US tariff increase on China may have a demonstration effect on the EU. However, unlike the United States, the trade links between China and Europe are closer, and the EU is more dependent on the China market.

Liu Bin said that at the same time, China’s new energy vehicles have entered the EU market, which has a "first-Mover advantage". Therefore, it is unlikely that the EU will adjust tariffs on a large scale and in a high amount like the United States. However, the EU may stand in a higher position and adjust taxes in the name of environmental protection.

　　The ancient mathematician Zu Chongzhi calculated pi to a few decimal places? This is the question of the small class of Ant Manor on March 11, 2025. Here is a detailed introduction to the chicken feed answer of today’s ant manor class on March 11, 2025.

　　Ant Manor is very fun. You can do charity while raising chickens, and you can get chicken feed for free while improving your knowledge.

　　The question for today’s class of Ant Manor is:

　　Guess: How many decimal places did the ancient mathematician Zu Chongzhi calculate the pi?

　　A, seven people

　　B, three people

　　Answer:Qiwei

　　Analysis:Zu Chongzhi’s greatest contribution was to make Pi accurate to seven decimal places, that is, to 3.1415926 to 3.1415927, which was the most advanced achievement in the world at that time.

　　The above is the answer to the question in the small class of Ant Manor on March 11th, 2025.

　　 Recently, the list of "Car of the Year Who Know Car Emperor in 2020" was officially released. This annual car list is based on the evaluation results of "Knowing Car Emperor’s Actual Measurement" in 2020, which is different from the evaluation based on the subjective feelings of car editors. Knowing Car Emperor judges by the measured data results, which brings consumers a more objective and real annual car list and provides users with a powerful reference for car purchase.

　　 It is understood that the "Know Car Emperor’s Actual Measurement" is that the original team of Know Car Emperor selected more than 400 popular models in the market according to the user’s attention to the models, and conducted a unified standard practical test, including data such as "safety", "space", "energy consumption", "performance and handling" that users are most concerned about, and finally formed an objective and reliable evaluation database, and sent users a simple and easy-to-understand "automobile configuration manual".

　　Know the car emperor’s annual car announced seven awards, a number of popular models on the list.

　　 The 2020 annual car list includes seven awards, including the best safety model of the year, the best family car of the year and the best electric car of the year.

　　 In the test of knowing the car emperor, Volvo XC60 became the first AEB test full score model. Moreover, with its amazing performance in elk, braking and body structure safety, it has become the best safety model of the year.

　　 Know the car emperor’s best family car of the year, won by Honda Odyssey Rui Hybrid. It has good performance in space, fuel consumption and quality stability. Coupled with a good rate of preservation, it has become an excellent choice for family cars.

　　 Since 2020, electric vehicles have become the trend of the times, and it has also become the measured object of the original team that understands the car emperor. The results show that Weilai ES6 won the best electric vehicle of the year with its strongest comprehensive strength. No matter in driving quality, sports performance or intelligent safety, it is the most balanced electric vehicle in the electric vehicle industry at present.

　　 The actual measurement has gone through the unified measurement process, including "static acceleration test", "braking distance test", "Elk test", "Jingang circuit lap speed test" and "fuel consumption test". All models have been repeatedly tested by the same professional racer in the same professional racetrack for more than 100 times. Moreover, they all use equipment and test methods and standards that meet international standards. Taking the Elk test as an example, more than 300 vehicles strictly implement the ISO3888-2 international standard, and each vehicle will be tested for nearly 20 times, constantly approaching the limit posture of the vehicle, so as to fully quantify the safety and handling of the vehicle. In addition, the actual measurement also creatively joined the original project of knowing the car emperor-the lap speed test of Jingang circuit. At the full speed of each car, the measured team who knows the car emperor records its lap speed, straight tail speed, low-speed corner, high-speed corner, etc., so as to effectively grasp the overall mobility of the car. Under the unified and professional measurement of knowing the car emperor, the list data is more objective and reliable.

　　 In addition to the above three award-winning models, Know Car Emperor also divided the rest of the award list in detail according to the characteristics of the models and the demand for vehicles: McLaren 720S won the Best Performance Car of the Year by virtue of its excellent power and aerodynamic design; Land Rover Defender passed all the test items in the test of Chedi off-road base and won the best off-road vehicle of the year. Tesla MODEL S won the fastest accelerated model of the year with the acceleration of "Tubang Class"; Ford New Transit won the Best Tool Car of the Year for its excellent performance in terms of the maximum volume of the interior space, the width and depth of the trunk opening.

　　Dedicated to the professional evaluation of automobiles, bringing valuable content to users.

　　 After long-term development, China has become the largest automobile production and sales market in the world. However, with the increasing popularity of automobiles, various brand models emerge one after another, and the market information is increasingly huge, which greatly increases the cost and difficulty of consumers’ car purchase decision.

　　 Compared with developed countries, China’s automobile evaluation system is still in its infancy. Most of the existing evaluation systems lack unified standards, are mixed with subjective factors, and the evaluation results have certain errors. Consumers lack a scientific and professional reference index for car purchase. In this context, as a professional automobile media in China, car owners can learn from foreign experience and integrate their own advantages to provide consumers with more accurate car purchase guidance.

　　 Knowing the car emperor’s actual measurement not only follows the international professional evaluation process and standards, but also creatively adds original actual measurement items to the China automobile market, so as to create an automobile evaluation system serving China automobile consumers. Relying on the professional testing team, testing site and equipment, Knowing Car Emperor not only forms a measurable and referential standard for China automobile testing, but also forms a more professional and fair automobile selection system, setting a brand-new benchmark for third-party professionals to participate in automobile evaluation.

　　 Up to now, Master Car has a very comprehensive vehicle evaluation database, and based on standardized venues, professional tools and equipment, and industry-recognized testing methods, it has gradually established a perfect evaluation system for Master Car, including unique active safety evaluation standards, track performance testing standards and off-road ability testing standards. It provides users with reliable, retrievable and comparable vehicle evaluation data products.

　　 For a long time, the team who knows the contents of Chedi insists on providing users with professional, data-based and most referential documentary evaluation contents based on the needs of users. In order to ensure the authority of evaluation and disassembly contents, the team not only needs to consult experts frequently, but also make up a lot of knowledge of materials science. The 2020 Car of the Year, which was selected this time, provides accurate reference for consumers with car purchase needs by subdividing the award-winning models, so that users can choose models as needed. In addition, there is an original evaluation channel in the station, which can help customers better understand the performance and detailed evaluation data of the vehicle.

　　 In the future practice, Knowing Car Emperor will continue to lead the new trend of automobile evaluation in China with strict and scientific evaluation procedures and standards, and build a weather vane for the automobile industry. While helping consumers to obtain more convenient and scientific car purchase information, it will also help high-quality car brands stand out in the evaluation and promote the Excellence and healthy development of the automobile industry.

　　Cctv news(Reporter Wang Jiazhu) It takes about an hour’s drive from downtown Xi ‘an to the west along Huanshan Road to reach zhouzhi county. At the end of November, the season has passed light snow, and the Guanzhong Plain is getting colder. However, the villages in Luoyu Town at the northern foot of Qinling Mountain are full of vitality.

　　On November 30th, which lasted more than two months, the reconstruction and construction of beautiful countryside in 13 administrative villages in two districts of zhouzhi county was completed on this day.

　　When Jiang Anshun, a villager, walked out of his house, he couldn’t hide his excitement when he saw a new, clean and tidy village street in put in order, white walls and gray tiles, a simple and elegant farmhouse and leisure square, and the distinctive beautiful countryside logo at the entrance of the village. He said: "I didn’t expect my hometown to become so beautiful."

　　Zhouzhi county, a land sheltered by the Qinling Mountains, is named after "the mountain song is terrible and the water song is awkward". It is adjacent to the Qinling Mountains in the south and the Weihe River in the north. It is known as the "Golden Week" and is the west gate of the provincial capital Xi ‘an. It has a good natural ecology, is a national ecological demonstration county, and has a profound cultural heritage.

　　According to the "Implementation Plan for Revitalizing Beautiful Villages in zhouzhi county during the 14th Five-Year Plan (2021-2025)" formulated by the zhouzhi county County Party Committee and the county government, the construction projects of zhouzhi county Beautiful Village Demonstration Area (Louguan Mazhao Area and Luoyu Area) where the above 13 administrative villages are located are listed as key projects in the county.

　　On September 18th, 2021, Xi ‘an Construction Engineering Group successfully won the bid for the construction of this project, and ran into the site 10 days later, starting a two-month reconstruction.

　　Prior to this, the Group had successfully completed the renovation project of human settlements in beautiful countryside, Yinji Central Village, Zhangbaling Town, Anhui Province, and the construction tasks of key demonstration projects in provinces and cities such as the 2020 cultivated land upgrading project in Nayong County, Guizhou Province.

　　The construction of beautiful countryside is a systematic project, which must be combined with geography, natural resources, cultural accumulation, folk customs, industrial structure and its own characteristics. Because of the village system, it is necessary to make a good construction plan, not only pay attention to the coordination with the surrounding environment, but also shape the village’s own characteristics and characteristics, and inherit the historical folk culture to ensure the scientific and rational planning and fully demonstrate the farming culture and beautiful characteristics.

　　Zhang Jingjing, director of planning and design of Xi ‘an Construction Engineering Municipal Transportation Group, who is in charge of the project transformation, said: "Highlighting rural flavor, reflecting homesickness and creating rural rhyme are the top priorities of beautiful countryside’s image design, and we have made every effort to create ‘ There are mountains, water, fields and houses ’ The design scheme of the Mazhao area in the foothills and the Luoyu area with the theme of humanistic leisure town and eco-tourism resort is also to make ‘ The countryside is more like the countryside ’ , avoid ‘ One side of a thousand villages ’ Guide the village to develop in the direction of market town. "

　　Specifically, in the process of construction, Luoyu District mainly relies on the advantages of human landscape resources such as Luoyu Reservoir and the site of ancient Luoguo, and strives to make Luoyu Town a characteristic scenic spot for citizens to relax through the design idea of humanistic leisure town and eco-tourism resort, and vigorously develop rural tourism, leisure vacation, sightseeing agriculture and other industries.

　　Louguan Mazhao area is close to Qinling Mountains in the south, which is rich in water resources and is an important local kiwifruit planting area. The design idea of this area is mainly to improve and transform the public space, integrate the relevant design elements of kiwifruit into the landscape, and guide the renovation of the village style, so as to enhance and expand the brand influence of "Zhouyi Village" kiwifruit.

　　Zhang Jingjing said that the 13 beautiful countryside in these two districts should create their own characteristics in the construction. "In the end, we have completed the construction goal of a core flagship brand, a tourist service center, a string of village tourist routes, a characteristic village lane in Guanzhong, a group of high-end boutique homestays, an exhibition hall for agricultural and sideline products, a number of farming experience projects and a number of online celebrity punch cards."

　　In the project transformation, Xi ‘an Construction Engineering Group planned from a high starting point, built with high standards, fully carried forward the spirit of "Iron Army", seized the progress of the construction period, actively practiced the Group’s standardized construction norms and implemented the "five full coverage" and other related policies during the project construction. In the difficult times when the epidemic occurred repeatedly, the project department of Xi ‘an Construction Engineering Group chose not to stop construction, and insisted on construction during the Mid-Autumn Festival and National Day holiday. Their busy figures were all over every village.

　　"Xi’ an Construction Engineering has worked hard and worked overtime. In order to complete the construction task on time, it has worked tirelessly, rain or shine, and has been recognized by the broad masses of cadres and masses." Wang Jie, deputy mayor of Luoyu Town, said.

　　The data shows that by the end of November 2021, the roadway reconstruction in two districts of zhouzhi county has been completed by 30km, gravel paving by 7km and roadside railings by 1800 m; Clean up 4000 cubic meters of garbage and sundries, including 100 broken walls; More than 200 newly planted trees; Shrubs are planted in 3,500 square meters, with a total greening area of 20,000 square meters. Laying drainage cover plate for 1.5km.. At the same time, 15 new cultural squares were built, covering an area of 6,543 square meters; The newly-built cultural and leisure corridor is 540 meters. The entrance space of the village in Louguan Mazhao area has been reconstructed in four places, with a total area of 820 square meters; 2 new regional signs; Renovate the facade of street-facing buildings by 20,000 square meters, renovate advertising slogans by 5,130 square meters, and draw rural cultural walls by 8,470 square meters.

　　In more than two months, the village has taken on a new look, and a "clean, green, smooth and beautiful" beautiful countryside scroll has been woven at the northern foot of the Qinling Mountains.

　　This earth-shaking change, the local villagers feel the most profound: "In the past night, this passerby did not dare to leave, and now the street lights are installed at night; In the past, when it rained last day, the whole family had to wear rain boots. Now it doesn’t have to wear rain boots for a month or two, the road is wide, the streets are neat, beautiful, and everything is fine. " A villager said.

Luoyu entrance signs

　　With the completion of the beautiful countryside project, in early December, people from nearby villagers, Zhouzhi County and even Xi ‘an City came here by car. This also allows the local government and villagers to see the business opportunities for further developing tourism, leisure agriculture and other industries. Take Zhouyi Village in Mazhao Town as an example. On the basis of this year’s kiwifruit harvest, this village has also developed 40 farmhouses and is building a homestay economy with high standards.

　　A person in charge of Luoyu Town, zhouzhi county said: "The dividends of beautiful countryside construction will continue to be released, which will greatly help us achieve the win-win goal of making tourists more satisfied and increasing villagers’ income."

　　Magpies can be said to be the most common birds in rural areas of Guanzhong, especially in the countryside near the northern foot of Qinling Mountains, on the big trees in front of and behind people’s houses, and among the branches on the banks of ditches in rural areas. Magpie looks very festive, with a round head, a pointed beak, a fat body, a long tail and feathers in black, white, blue and purple, which can be said to be loved by everyone. What the villagers like best is its chirping sound, which they think is an auspicious sound. "When the magpies chirp, the guests will come", which is a favorite saying in our village.

　　I also like magpies for two reasons. First, I have lived in the countryside since I was a child. Magpies are more common and seen, just like my neighbors. When I am familiar with them, I am happy. Second, I think this kind of bird looks good and sounds good, unlike sparrows, which gather in groups in front of people’s eaves all day, chattering, making people upset, and sometimes harming crops and making people hate it. Nor is it like an owl, whose voice is sharp and harsh, such as a sharp instrument crossing a slate.

　　In my memory, magpies are the most common in spring and winter, but they don’t seem to be seen much in summer. This may be the reason why the magpie’s whereabouts are not easy to be found in summer. In spring, magpies can often be seen in Yuan Ye, my hometown. They jump in the wheat field one by one, head by head, and look very fun; Or while chirping, slowly fly from tree to tree, and the tail feathers draw a beautiful arc. This season, magpies’ nests are also easier to find, mostly on tall poplars. Walking in the countryside, when I look up, you will see huge magpie nests, crouching peacefully among the treetops of Gao Yang willow trees, as if they were pieces of art.. The sky is pure and blue, not stained with a trace of dust. At this time, there may be wind, and the nest will gently shake with the wind.

　　Although it shakes, there is no need to worry that the nest will be blown down by the wind, because magpies are masters of nesting. I have lived in the country for many years, and I have seen many bird nests, such as those of swallows, sparrows and turtledoves … I think they are not as beautiful and strong as those of magpies. Sparrows make a nest out of a mess of grass. Sometimes, they don’t even build such a simple nest, but live directly under the eaves of others or among the trees. Swallows’ nests are exquisite, but they are also built on the beams of other people’s houses, and they like to use old nests, which are neither as big as magpie’s nests nor as beautiful as magpie’s nests. As for the doves’ nests, they are mostly built in the oblique branches of the trunk of a big tree, which is not only sloppy, but also extremely unsafe. When I was a teenager, I saw more than once that the village children climbed the tree to dig out the nest of the turtledove, and the turtledove flew around the tree in shock. Magpies, on the other hand, have no such worries. Their nests are mostly at the top of big trees, and village children can’t climb them. Even if they climbed up, because the branches at the top of the tree were too thin, the children were afraid of breaking the branches and falling to the ground, and did not dare to climb to the top to dig out the magpie nest. What’s more, the villagers also forbid children to climb the tree and dig out the magpie nest. Therefore, it is very natural that magpies are more common in their hometown.

　　In spring and summer, magpies are busy building nests, laying eggs and brooding, but in autumn, magpies seem to be more relaxed. This season, the young magpies have grown up, so they don’t need to be fed. There is plenty of food in the field, and they can eat without much effort. The full magpies are singing and playing in the fields, or in the big trees in front of and behind people’s houses. Only in winter, because of the lack of food and the cold weather, they seem sluggish and seem to be less active than in spring, summer and autumn. Magpies seen in winter are mostly foraging.

　　I have long known that magpies like to live in exile. In the past, during those years in my hometown, I also often saw it. However, in the past twenty years, it seems that I have seen fewer magpies in the plains and Sichuan fields. Sometimes I see it occasionally, and it is often one or two, and there are no groups. And the magpie’s nest seems to be smaller than I remember. Looking at it, it is about the size of a basketball and stands alone among the treetops of a small tree. Last winter, I went to Fengyukou, Qinling Mountain to play. By the Hongcao River, I unexpectedly met a large group of magpies. They were screaming and laughing, jumping and pecking in a mountainous area. That carefree, makes me fascinated. I was excited for a long time, and I stopped in a hurry and watched it quietly for a while. At that moment, my heart seemed to have returned to my familiar hometown and my distant childhood. In a trance, I saw my kind grandmother take a big red window cut of a magpie and stick it on the pane. And outside the window, it is a place of snow, a tree of Qiongzhi.
