Health code: press the shortcut key to resume work and production.

At 13: 24 and 15: 13 on March 19, the first batch of two free high-speed trains from Hubei to Guangdong started from Jingzhou Station in Hubei, and transported 1,631 Jingzhou migrant workers to 898 Guangdong enterprises. All of them applied for Hubei health code and passed the nucleic acid test. In the near future, 40,000 Hubei migrant workers will go to Guangdong to return to work with their health code.

With the orderly progress of resumption of work and production, the national mutual recognition of health codes is pressing the shortcut key. On March 20th, Mao Qunan, director of the Planning Department of the National Health and Wellness Commission and deputy director of the National Aiwei Office, said: "At present, the the State Council E-government Office and the National Health and Wellness Commission have provided three paths for mutual recognition and sharing across provinces. Please choose to implement them according to local conditions."

How to get through the health code information in each province, and what are the problems in the use process? The reporter conducted an in-depth interview.

Focus: health code embraces those who return to work.

How do mainlanders enter Hubei in the process of resuming work and production? On March 19th, Hubei Province issued a notice that people from other provinces can apply for Hubei health code through the "Hubei Office" App, the national "internet plus Supervision" applet, the Alipay applet and the "Hubei Office" WeChat applet, and pass through Hubei with the "green code".

At the same time, Hangzhou, Zhejiang Province took the lead in "embracing" the returning workers in Hubei Province. From March 18th, Hubei people can go back to work in Hangzhou with health codes without isolation. Why is Hangzhou moving so fast? It has to start with the health code more than a month ago.

In Yuhang District, Hangzhou, due to the large floating population and large flow, at the beginning of the epidemic, local prevention and control encountered a "pain point" problem-how to reduce personnel contact and paper duplicate registration. On February 4th, Yuhang District proposed to build a digital scheme as a digital health certificate during the epidemic period. As a result, Alipay, Nail, Alibaba Cloud and other teams worked with the local authorities to develop health codes. "During that time, everyone slept for two or three hours a day, and the product was iterated half an hour before it went online, and it was iterated half a day after it went online." The staff responsible for the health code project in Yuhang District said.

On the evening of February 7th, Yuhang, Hangzhou launched the first health code in China-"Yuhang Green Code". Yuhang residents can travel and return to work with the health code in their mobile phones. Subsequently, on February 11th, Hangzhou Health Code was first launched in Alipay, creating the red, yellow and green dynamic health code model.

The spillover effect brought by health code soon appeared. On February 16th, when some areas were still worried about the "three-return" personnel flow caused by the resumption of work, Zhejiang started to resume work by using the health code. That night, the first special train for people returning to work in China arrived in Hangzhou East from Guiyang North, the starting station, and nearly 300 Guizhou passengers returned to Hangzhou smoothly. On February 19th, Hangzhou West Lake Scenic Area was also the first to open.

In just two weeks, the health code has been promoted from one city in Hangzhou to 200 cities across the country, and it has gradually promoted mutual recognition. According to statistics, 25 provinces, municipalities and autonomous regions in China can receive health codes from Alipay. At the same time, the "national version" health code-epidemic prevention health information code, which was developed under the guidance of the General Office of the State Council, was first launched in Alipay applet, and has been available nationwide.

It is worth mentioning that Zhejiang Province has launched an international version of the health code in view of the actual situation of overseas Chinese, overseas students and other foreigners returning to Zhejiang. Appropriately distinguished from the domestic version, the international version of health code is classified into orange, yellow and green. By 12: 00 on March 16th, Zhejiang had distributed 72.092 million health codes, including 31,000 international versions.

Breaking the difficult point: data islands are being opened.

At 7: 30 pm on March 18th, six warm-hearted returning buses carrying 148 Hubei folks arrived at Yuncheng West Road, Baiyun District, Guangzhou City, Guangdong Province. The medical staff got on the bus to take temperature and check the health code. Li Xiande, a returning worker, said: "Guangzhou has long been my home."

On March 16th, Baiyun District was officially declared as the first administrative region in Guangzhou to recognize Hubei health code. Anyone who has returned from Hubei with a "green code" need not be isolated or tested. This policy has reassured people from Hubei to Guangzhou.

In Sanyuanli Street, Baiyun District, more than 6,000 Hubei nationals rented here before the Spring Festival, and more than 4,900 Hubei nationals returned to their hometown to visit relatives during the Spring Festival. Baiyun District People’s Social Security Bureau said that it will continue to open a through train for returning to work, arrange special personnel to follow up the work of returning to Guangzhou, lodging, entering the factory and entering the village (community), and open up the whole process of "point-to-point" transportation for employees returning to work to help migrant workers get to work safely and healthily.

In Shandong, Song Yuying, who lives in Jiaheyuan Community, Fulaishan Street, Yantai Development Zone, returned to her hometown in Heilongjiang in the New Year. Recently, she returned to Yantai because of the start of business. After Song Yuying returned to Yantai with the "Heilongjiang Health Card" issued by Suihua City, Heilongjiang Province, she completed the inter-provincial mutual recognition in the neighborhood Committee for 5 minutes and successfully changed the "Shandong Health Pass Card".

Mutual recognition, so that data islands in various places are being opened. From March 19th, all the cities in Shandong Province will recognize and release those who have mutually recognized and shared provinces as long as they can show their health codes, and guide them to apply for Shandong electronic health codes by using the "Lailu Declaration" module. For those who can’t show their health pass codes and who have not signed a mutual recognition memorandum, the policy of isolation for 14 days will continue to be implemented. At present, Shandong has promoted the establishment of inter-provincial mutual recognition mechanism of "bright code" and "transcoding" with 19 provinces with more personnel mobility.

Zhejiang and many places have realized mutual recognition of health codes. As early as February 28th, Hainan and Henan signed mutual recognition agreements on health codes with Zhejiang respectively. At present, Zhejiang has achieved mutual recognition of health codes with at least 10 provinces and cities such as Hainan, Henan, Sichuan and Hubei.

The use of health codes is also being further optimized, and some provinces have achieved one-time filling and mutual recognition. Nowadays, Hubei people apply for Hubei health code in Alipay, and they can return to their local jobs with the health code, so there is no need to apply for Hangzhou health code repeatedly. On March 18th, a group of migrant workers in Xianfeng County, Enshi Prefecture, Hubei Province just took the bus and returned to Hangzhou with their health codes.

Make up the shortcomings: realize mutual recognition and sharing of information in multiple ways

On March 21st, Mao Qunan said at the press conference of joint defense and control mechanism in the State Council: "We have realized mutual recognition and sharing of basic data. On the national national health information platform and the national integrated government service platform, the databases of confirmed and suspected patients, possible close contacts and county epidemic risk levels in COVID-19 were released, thus realizing the unified mutual recognition of the basic databases. "

Mao Qunan said that China has provided three paths for cross-provincial mutual recognition and sharing:

—— First, under the condition of not changing the existing local health password, the cross-regional mutual recognition function is added to the local health password through the data sharing of cross-regional epidemic prevention health information;

-Second, the local health pass codes are connected with the epidemic prevention information codes of the national integrated platform, and the epidemic prevention information codes on the national integrated platform are used as the intermediary to convert, so as to realize the mutual recognition of cross-regional health pass codes;

Third, for those areas that have not established the local health pass code, the epidemic prevention information code on the national integrated platform can be directly adopted.

At present, is there a "short board" in the process of mutual recognition of health codes? Mao Qunan believes that the difficulties in mutual recognition of health codes are mainly the differences in epidemic prevention and control situations and policies in different places. At present, the low-risk counties in China have accounted for 98%, and all provinces are speeding up the collection of catalogues of epidemic prevention health information in their own areas to the national integrated platform in accordance with unified data format standards and content requirements.

"From the current point of view, promoting mutual recognition of health codes in an orderly manner is also constantly optimized and iterated. This is a positive measure and the effect is worthy of recognition." Zhu Wei, deputy director of the Communication Law Research Center of China University of Political Science and Law, said.

Zhu Wei believes that because prevention and control involves public interests, the measures to introduce health codes are very timely. In this process, the collectors are informed and the government is fully involved, so it conforms to the provisions of the network security law and belongs to the scope of rational use of personal information.

"It should be noted that the health information collected is personal core information, and China should strengthen the protection of personal information security during the implementation process." Zhu Wei said.(Reporter Zhang Zheng, Lu Jian, Aring Zhang, Wu Chunyan, Zhao Qiuli, Wang Zhongyao, Fan Feng)

Teach children math.

"A cabin is only 6 square meters. If you live in it, how will you decorate it?"


On December 25th, 2023, in the "Research and Practice Class of China Mathematicians Entering the Primary School Classroom" taught by Hua Yinglong, Vice President of Beijing No.2 Experimental Primary School, interesting questions deeply attracted the sixth graders.


The Mathematics Curriculum Standard for Compulsory Education (2022 Edition) points out: "The content design should reflect the application of mathematics in nature and society, show the great mathematicians in the history of mathematics development, especially the famous mathematicians in ancient and modern China, and the role of their mathematical achievements in the development of human civilization, and enhance students’ patriotic feelings and national pride."


It coincides with the 90th anniversary of the birth of Chen Jingrun, a famous mathematician in China. Hua Yinglong can’t help but think about the requirements of the curriculum standard: What kind of collision will happen when the world-famous China mathematician enters the primary school classroom? I want to chase the "brightest" star with my children!


Plant the seeds of curiosity


This class begins with the sharing of reading experience before class. Before class, the students previewed the reportage Goldbach conjecture in advance. In class, the students scrambled to share their feelings.


"Although some people discriminated against him, he didn’t waver in his love for mathematics. He was always calm, and his tolerant spirit was worth learning."


"I want to say to Chen Jingrun that you are really amazing. You were born in a family with no math environment, but you have made such achievements through hard work."


"What impressed me most was that Chen Jingrun studied hard in a 6-square-meter hut despite the difficult conditions."


…………


Students talked about being moved by Chen Jingrun’s spirit of studying and studying, and began to notice the mathematical element of "6 square meters" under the guidance of the teacher.


Hua Yinglong asked, "What kind of math topic do you think you can make up about the 6-square-meter hut?"


"Chen Jingrun’s room is 6 square meters, and their chimneys account for one-sixth of the room. How big is the living area?"


"The room is 6 square meters in total, and a chimney has cut the room into a corner, which is one-sixth of the room area. How big is this corner plus the total room area?"


…………


According to Hua Yinglong’s questions, the students expressed their opinions and collected five different proposition ideas. Hua Yinglong immediately gave his own examples. The students called "simplicity" and "logic", and an ordinary application problem set off a hearty "brainstorming" between teachers and students.


The reading method with "questioning" as the main guidance makes students experience the fun brought by mathematics reading, and guides students to think deeply and be eager to try after thinking.


After mastering more clues, students are more curious about the "6 square meter cabin". Hua Yinglong continued to ask: "What is a 6-square-meter cabin like?" He asked the students to draw a plan of the hut. With the help of students’ work sharing, Hua Yinglong has drawn out one enlightening question after another.


Through mathematics to restore the hut, children’s eyes look at the hut in a variety of ways: some are trapezoidal, some are square, some are marked with the position of the door and bed, and careful students mark the size of each layout …


"Teachers’ teaching design should read the world from a mathematical perspective, which is fascinating," Hua Yinglong said. "As a guide for students’ mathematics learning, we should plant a seed for them, hoping that one day, this seed will blossom a flower of’ everything counts’."


Bold trial and error in exploration


Around the "hut", Hua Yinglong took the students to solve the side length, and the "mathematical flavor" became stronger and stronger. At this time, a quick student confused the area and perimeter, and the students corrected his algorithm one after another. Hua Yinglong praised the student’s quick response and bold speech: "Children, in reading, not only reading, but also thinking. Every mistake is a reminder. We want to thank this classmate for reminding us." There was applause at the scene.


When calculating the side length of the hut, the students encountered a difficult problem-they had not touched the square root and could not continue to calculate.


"Children, we can’t make a square, can we still count?" Hua Yinglong asked. He didn’t impart knowledge beyond the outline, but left time for students to think. When a student tried repeatedly on the toilet paper and found the answer by reverse deduction, Hua Yinglong showed it to everyone with surprise and led them to summarize this valuable thinking process:


"Children, did this classmate try it right just once? No, he also found the answer by mistake, right? " Hua Yinglong once again guides students to correctly look at mistakes in learning. In such a class, students’ frustration tolerance is strong.


"Making mistakes is something everyone has to experience, including teachers." Hua Yinglong said, "We have to tell students that mistakes are often reminders, reminding us to calm down and think: Where is the problem? Why is it wrong? What new possibilities will there be? What new problems can you think about? "


"Where is the 6-square-meter hut and what is it really like?"


In order to give the child an accurate answer, Hua Yinglong shared his "journey to find the truth" after reading relevant books and materials, and went to the address of his former residence "No.88 Zhongguancun Street" in the materials to find out, but found that this was not the location of his mathematics institute. When I went to Fujian, I learned that there was a "Chen Jingrun Experimental Primary School" in the local area. I went there quickly, but I didn’t get the answer … Despite the twists and turns, with the help of Song Li, Chen Jingrun’s nephew, the real hut emerged a little bit: the room was square, and it became a "knife handle" shape after being occupied by the garbage passage. Because the space was narrow, people had to close the door before they could barely stand open …


Hua Yinglong’s exploration process of constantly trying to find a "real cabin" inadvertently set the best example for students.


Give students a bigger world.


"Students, suppose you enter Chen Jingrun’s cabin now, what do you want to say to him?"


As the class draws to a close, Hua Yinglong throws out the last question of this class. As early as in the open space next to the podium, he outlined the spatial structure of the hut with tape, suggesting that students take a walk in the "hut" and feel the living space of 6 square meters.


Some children bluntly said, "I love this mathematician very much, and I hope he will pay attention to his health and live in a big house." Some children felt "the sense of accomplishment gained by tireless knowledge" through repeated thinking, and some children called "Mr. Chen Jingrun is so great that in a difficult environment, he has confirmed the" Goldbach conjecture "that even the great mathematician Euler has not confirmed …


At this point, students’ feelings are not only the absorption after reading, but also the spiritual baptism after the classroom and teachers jointly verify and explore.


The students read the ten characters written by Hua Yinglong on the blackboard in unison-"A humble room grows into a superstar, and hardships make a great man". At that moment, the little boy seemed to have crossed time and space, ignorant and firmly paying tribute to the mathematician.


What can mathematics leave for students?


"A good math reading class is to give students reading energy and spiritual nourishment." Hua Yinglong replied in class, "I always think that education is humanized, which is the highest realm pursued by education." I am a primary school math teacher, but I don’t teach math. I use math to teach children. "

Central enterprises talk about safety | China Construction Group: the work method of safety management of "conductor" in construction site!

China Construction Group has always firmly established the overall national security concept, put safety development through the whole process of production, operation and management, and constantly strengthened the bottom line thinking and red line consciousness; Implement the fifteen measures of safety production of the State Council Safety Committee, and make overall plans to promote the investigation and rectification of hidden dangers of major accidents.2023Action, etc., to build a solid foundation for safety management; Further promote the development of science and technology, tackle the safety research topics, independently develop and apply the "China Construction Smart Security Platform" to promote the reform of safety management; Continue to carry out special education activities such as "behavioral safety star" and "safety training camp", strive to create a good safety culture atmosphere of "I am safe, you are safe, and safety is under construction", and escort high-quality development with high-level safety.

 "Everyone talks about safety, and everyone will respond to emergencies". The leasing division of South China Company of China Construction Second Bureau promotes the transformation of public safety governance mode to pre-prevention, widely popularizes safety knowledge, solidly carries out safety training and emergency drills, vigorously cultivates safety culture, strictly implements various safety responsibility measures from reality to detail, and lays a solid foundation for the high-quality development of enterprises.

Liu Zhengnan, a safety supervisor in the production line, said,The building is a solidified note, and the tower crane is the conductor on the construction site. Watching the tower crane wave a long baton every day to coordinate and transport various materials and components, and ensure the normal construction work in an orderly manner, I am extremely proud as a tower crane safety management worker. Today, let Liu Zhengnan take us to see what the safety management of tower crane jacking operation has.

Tower crane, also called tower crane for short, is an important vertical transportation equipment for materials in the construction process of today’s construction projects, which has the characteristics of large volume, heavy weight, high height and dense working environment. The leasing division of South China Company of China Construction Second Bureau is mainly responsible for the leasing and dismantling of large-scale mechanical equipment, and is operating tower cranes.170The installation and disassembly work of the remaining units and tower cranes has reached the average monthly.15Number of times, the amount of lifting and node lowering operations reached the average monthly average.350Remaining sections. In order to ensure the safe and stable development of the enterprise and the safety of people’s lives and property, the Division has formulated a number of management systems around the key points and difficulties in the safety management of tower crane installation, jack-up, node reduction and demolition.

Lifting and jointing of tower crane is a dangerous operation. In order to let everyone know the safety control measures of tower crane lifting operation, Liu Zhengnan will lead everyone to use it."Mini Tower Crane" explains from the aspects of pre-operation preparation, pre-operation inspection, jack-up operation process and jack-up acceptance.

Preparation before operation


1.Pay attention to the weather and prevent the impact of bad weather;

2.Conduct safety technical disclosure and pre-shift meeting to confirm that the operation certificate is valid, the health status of personnel and the equipment are in good condition;

3.Set up a cordon and prohibit irrelevant personnel from entering.

Pre-operation inspection


1.Check the standard section for deformation and welding, and clean up the dirt;

2.Check whether the connection between the sleeve frame and the rotary lower support is firm;

3.Check whether the oil quantity of the hydraulic station is within the acceptable range;

4.Check whether the cable length meets the height requirements.

Jacking operation process


1.Rotate the lifting object to the jacking direction for balancing, and close the rotary brake;

2.Push the anti-out-of-stock, so that the jack-up beam is locked on the standard step;

3.Operate the hydraulic station for "cylinder test", and the pressure value of the oil pump should remain stable;


4.In the process of jack-up, turning, lifting and luffing are strictly prohibited;

5.Do a good job in wind speed monitoring and pay attention to weather warning in real time;

6.After the jack-up operation is finished, connect the pin shaft or bolt between the rotary lower support and the standard joint.

Jack-up acceptance


1.Measure the verticality of tower crane to ensure that it meets the specification requirements;

2.Check the safe distance of the tower group to ensure that it meets the specification requirements;

3.Complete self-inspection and joint acceptance, and use it only after it is qualified.

Spinning off "Know the Car Emperor", ByteDance may harvest the first IPO.

Recently,According to The Information, citing people familiar with the matter, ByteDance plans to raise $700 million to $800 million for Know Car Emperor, which will be used to promote the independent development of Know Car Emperor and pave the way for its IPO.

People familiar with the matter said that sequoia capital china, as the lead investor in this round of financing, is expected to invest 400 million to 500 million US dollars. At the same time, KKR and General Atlantic, two well-known investment institutions, also plan to participate in this round of financing. After the completion of this round of financing, the valuation of Knowing Car Emperor is expected to reach $3 billion.

Interface News asked ByteDance for verification on this matter, but no response was received as of press time. However, some people told the interface news that the car emperor is indeed splitting from bytes and realizing independent financial accounting.

All the above investors have participated in financing in ByteDance. amongSequoia ChinaexistIn 2014, the company became a shareholder in the C round of financing.,And become one of the major shareholders of the company..Participating parties: Transatlantic Capital and KKRruleParticipated in ByteDance’s 2017 E round of financing and 2018 Pre-IPO round of financing respectively.

If it is successfully listed, it will be operated for 7 years.Knowing Car Emperor will be the first IPO in ByteDance’s big family.According to industry speculation, bytes may be inIn the absence of its own IPO.,borrowKnow the car emperorThe listing of the company provides a return on investment for the old shareholders who have been running for many years.

According to Tianyancha, at the end of 2023, Beijing Zhicheti Technology Co., Ltd., an affiliated company of Zhicheti, had undergone industrial and commercial changes.,Today’s headlines of ByteDance have withdrawn from the shareholding structure of the company.,thatThe major shareholder was changed to be established on December 8, 2023.ofXiamen Zhiche Technology Co., Ltd. holds 100% of the shares. There are two founding shareholders of Xiamen Zhiche Family.amongHe Jian, president of Che Di.forHolding 60%ofstrong stock holder.

Know the car emperorAuto channel, who was originally born out of today’s headlines.,Personalized recommendation algorithm hatched by ByteDance commercialization department and inherited from headline system.andFull platform big data,And launched an independent App in 2017..In January 2018, auto channel made headlines today.formalRenamed to understand the car emperor channel; In October 2019, I knew that the car emperor was on the live car..

In July 2023,Knowing the car emperor announced that it has been fully integrated with the car content of Tik Tok, Today’s Headlines and Watermelon Video. Knowing the car emperor as the overall operator, it will co-ordinate resources at all ends..After the integration, the daily life of automobile users on the four platforms reached 310 million person-times, the daily average page views of automobile content exceeded 5.6 billion times, and the operation covered more than 6.34 million automobile creators.

Starting from an initial channel, Knowing Car Emperor began to expand related businesses.Currently mainly for users.Provide car number, car circle, evaluation system, car library, car classification, etc.Car content and car selectionservice,Provide solutions for automobile brands and dealers..

According to the Data Research Report of Mobile Internet Industry in Q3 2023 released by Aurora, the average DAU (Daily Active Users) of automobile information platform in Q3 2023 is compared. In the first echelon, car home, Car Master and Easy Car rank among the top three.

In 2000 and 2005, two automobile information websites, Easy Car and car home, were established respectively, which quickly beat the traditional portals by virtue of their advantages in traffic and user accuracy, attracting the attention of consumers and automobile companies. Among them, easy carLi Bin, founder of WeilaiFounded and listed in the United States in 2010,Home of the carThen byanotherhomeNew forces of building cars,Li Xiang, founder of LIFounded and landed in the US stock market in 2013,In March 2021, it returned to the secondary listing of Hong Kong stocks..

Know the car emperorThe corner overtaking is mainly because it stands on the tuyere of short video.Short video form of UGC (User Generated Content)Breaking the graphic content restrictions of traditional websites such as Easy Car and car home, and putting the main battlefield on independent APP, the emerging automotive information application as a mobile platform quickly ranks among the first echelon in the industry.

However, in terms of income structure,Know the car emperorLike the traditional car information website, it still relies mainly on"cluesservice"And advertising.Among them, "clue service" refers to the sale of consumer clues that have been selected and registered on the platform toCar companies and 4S stores and dealers. For reference,The first quarter of 2024Car home’s cue service revenue was 726 million yuan, accounting for 45.1% of the total revenue of 1.609 billion yuan, exceeding media revenue (327 million yuan) and online marketing and other income (555 million yuan).

andCPT mode used by car home and Easy Car.,That is, the clue fee is paid for the platform by the user’s usage time.Different, knowing the car emperor changed the cooperation mode toCPS mode (Cost Per Sales) of paying the lead fee according to the volume..Although on the surface, this enables dealers to better realize transaction conversion, in fact, manyDealers believe that this settlement mode leads to uncontrollable budget.The cost has risen sharply, soThe refusal to cooperate caused a storm at that time.

Clue service also brings privacy security risks to consumers.On January 22, 2021, among the first batch of 157 APPs infringing on users’ rights and interests released by the Ministry of Industry and Information Technology, car home’s car quotation was named because of two problems: "illegal collection of personal information" and "the app is forced, frequent and excessively demanding authority".

On the black cat complaint, there are 544 complaints about the car owner. Many users said that they were often harassed by dealers, used car dealers and other telephones because they registered their personal information on the platform.

On the core content,Know the car emperorIt has also caused quite a controversy recently.

The platform gives on the one handThe creators provided a lot of support measures.,On the other hand, it also producedA series of original programs,For example, the comparative disassembly and horizontal evaluation of multiple models, the long-term test of winter endurance, etc.,"Seriously, you have to understand Che Di."Is its propaganda slogan.

The source of controversy is its winter test in 2023. In December 2023,Know the car emperorwhatIn the extreme low temperature of Mohe River in Heilongjiang Province,Tested 5More than 0 mainstream cars,andInvited 25 groups of car companies, media, industry organizations, user representatives and other on-site observation and live broadcast.

Subsequently, the platform announced the results of the winter test.In the ranking of pure electric endurance achievement rate of hybrid vehicles, only three models have achieved a pure electric endurance achievement rate of more than 50%, namely BYD Looking Up to U8, BYD Song PLUS DM-i and Ideal L7..The extended range version of the M7 is ranked first from the bottom with a endurance achievement rate of 31.6%. Geely, Great Wall’s many models in the test reached the endurance rate did not exceed 40%.

This has caused many car companies to question.Wen Jie automobile issued a documentexpressUnderstand that the car test process "seriously deviates from the user’s real use scenario", and attach the detailed car data of the vehicles participating in the test, including the number of door opening and closing, the temperature inside the car, and the heating time of the air conditioner. In the process of servicing the boundary M7, the tester has operated to open and close the doors and windows for more than ten times, of which the longest time is more than 3 minutes, resulting in only 74.9% of the battery power when the boundary M7 leaves.

Yu Chengdong, managing director of Huawei and chairman of BU, a smart car solution, issued a document the next day.Know the car emperorWinter measurement"cheat people’s test, misleading people"; Yang Xueliang, Vice President of GeelyCall it a test"unscientific, not rigorous, and the conclusion is not convincing"; Great Wall MotorAlso said, "Knowing the unscientific and imprecise test of Chedi not only misleads users, but also damages their own credibility."

faceQuestioning, knowing the car emperor emphasized that "the test standards are completely unified and all models are treated equally" and conducted the second live broadcast evaluation on December 14.

However, because its business model is mainly based on the launch of car companies, the content neutrality of knowing the car emperor is still suspected by all parties.At the beginning of this year, Huawei HarmonyOS Zhixing’s brands such as Wenjie and Zhijie.Be exposed to pauseCooperate with "members" who know about Car Emperor, car home and Easy Car.

In addition, in recent years, many car brands are more willing to cooperate with themselves to complete their marketing strategies through offline stores and online channels, and the founders and responsible persons of various brands have also appeared.Online celebrity flow effect,The advertising and "clue service" business growth space of automotive information platforms is getting smaller and smaller.

Car home’s growth has basically stagnated in the past few years.,Compared with the highest market value in history, it has dropped by about 80%. Easy carThen in 2020,Announce the completion of privatizationSell yourself "Tencent,By the time of delisting, its share price was only $16.

Understand that Chedi is also looking for room for business expansion under pressure.Gradually expand to automobile trading and after-market services.

In 2021, Knowing Car Emperor launched the car trading service, and in 2022, it opened an offline new car experience store and a used car trading market. In 2023, Know Car Emperor further entered the offline automobile trading stores and opened the "Know Car Emperor Automobile Mall".,The store has an overall area of about 8,000 square meters and can provide one-stop transactions such as new cars and used cars..

However,Automobile after-service marketThe competition is equally fierce, except forTu Hu yang chealreadyOccupy a certain market scale,JD.COM, AlialsoLaunched successivelywatch from a height or distanceJD.COM keeps cars and Tmall keeps cars..And from the light asset platform of automobile information to the heavy asset platform.Offline automobile service business,Know the car emperorIt also needs to pay more investment and wait for a longer payback period.

Even if ByteDance can successfully list the car emperor on the capital market, itsWill still face a severe test.

One vaccine prevents 12 cancers? Stop joking!

  A "sky-high" vaccine that can prevent 12 kinds of cancers is said to be quietly popular among wealthy people.

  Some media reported a few days ago that Hong Kong MDX Medical Group released the "DCV Cancer Vaccine", which can prevent more than 12 kinds of cancers, including prostate cancer, breast cancer and lung cancer, with an injection of 98,000 yuan.

  And such a good thing? The reporter of Science and Technology Daily immediately connected Zhi Xiuyi, the director of science popularization propaganda department of China Anti-Cancer Association and Professor xuanwu hospital of Capital Medical University, to hear what he said.

  Is it pseudoscience? Try these three "magic mirrors"

  "What cancer can be cured? Judging from this advertisement, it can basically be judged to be pseudoscience. " Zhi Xiuyi told the Science and Technology Daily reporter that, if nothing else, as far as lung cancer is concerned, there are small cell lung cancer and non-small cell lung cancer; Non-small cell lung cancer includes squamous cell carcinoma, adenocarcinoma, squamous adenocarcinoma and large cell carcinoma; Some cancers are derived from epithelial cells, while others are derived from mesothelial cells … … It is impossible to prevent only one kind of lung cancer, let alone prevent 12 kinds of cancers together.

  This characteristic of malignant tumor is called "heterogeneity" in academic circles, which can be roughly understood as that even if it is classified as the same tumor, it may be completely different. Some academic articles show that there are two kinds of heterogeneity: one is that the gene mutation of tumor cells of the same patient is different at different stages of tumor occurrence; The other is that different patients have the same tumor, but that "same" is not necessarily the same, just the same phenotype does not mean that the genotype is the same.

  Zhang Xuemin, an academician of China Academy of Sciences, used a very vivid analogy to explain "heterogeneity" at an academic seminar. He said: The genome in the human body is like taking a disk and dropping it underground. No fragments are the same twice, and no two tumor patients have the same mutation. The human body has 3 billion base pairs, and it may not develop tumors if it is changed by tens of millions. The main problem in treating tumors is to find out which one is the driver mutation, so that targeted therapy can be possible. At present, scientists are using big data to find the most critical driving mutation genes (which can be understood as core components). According to clinical data and proportion, thousands of tumor driving genes have been found.

  It can be seen that it is impossible to control the broad-spectrum WT1 gene only as mentioned in the product description of "DCV cancer vaccine" (assuming that the injected substance can control the gene first), and the so-called "universal gene" is totally false.

  Therefore, "omnipotent, cure all diseases" is the first "mirror", especially for malignant tumors with complex mechanism, it is even more impossible to "take one enemy and ten".

  "This kind of pseudoscience has another feature, and there are no specific research institutions and research events. If it is a real thing, there should be specific scientific research projects and scientific research results data, and the results should be displayed at international or domestic cancer conferences. " Zhi Xiuyi explained, "If it is clearly said that it is the work of a research institute or scientific research team of a certain university in the United States and a series of experimental studies have been carried out, then other teams of scientists should be able to verify this research, or introduce their research results and data at the ASCO meeting of the global cancer conference or the CSCO meeting of the domestic cancer conference."

  However, the "DCV Cancer Vaccine" released by Hong Kong MDX Medical Group did not disclose any clinical trial data, how related clinical verification was promoted, the effect of the third phase of clinical research, whether relevant papers were published in academic journals, and which scientists and research teams participated in the research work. To put it bluntly, this achievement is like being produced out of thin air and cannot be traced back.

  "Out of thin air, untraceable" is the second mirror, while "commercial manipulation and speculation for profit" is the third mirror.

  "Although the production of a fake news is out of thin air, it must be driven by huge economic interests." Zhi Xiuyi said that the research and development and innovation of new anti-tumor drugs need a lot of money, especially in the clinical verification stage, which requires hundreds of millions of funds.

  At this time, the methods of speculating the concept, raising the stock price, and financing have become a brilliant move for many capital players, and fake news has also become one of the springboard for them to "play" the capital market. As long as the sales performance and followers take the lead, this wave of operation may attract investment and become the so-called "model" of commercial manipulation. As some media have analyzed, its commercial essence is "cutting leeks".

  Don’t let pseudoscience "fry" the tumor vaccine

  This is a lie rumor about tumor vaccine, but "tumor vaccine" is a real new biotechnology in recent years.

  People are familiar with: cervical cancer vaccine, hepatitis B vaccine and so on.

  "In principle, the principle of preventive tumor vaccine is to prevent microbial infection from inducing tumors. For example, cervical cancer vaccine is to prevent polyoma virus; Hepatitis B vaccine is to prevent liver cancer; Prevent EB virus and nasopharyngeal carcinoma; Prevent Helicobacter pylori and prevent gastric cancer. " Li Zhongming, editor-in-chief of Contemporary New Vaccine (first edition), who once worked as a censor in the FDA of the United States, explained to the reporter of Science and Technology Daily: At present, preventive tumor vaccines must be related to microorganisms, and only therapeutic vaccines are targeted at tumors.

  Focus! Tumor vaccine is divided into preventive and therapeutic, and injected into healthy people and tumor patients respectively.

  Preventive tumor vaccine is only aimed at tumors caused by viruses and other microorganisms. Because it can clarify the formation mechanism of tumors, it can prevent them, and many vaccines have been put on the market.

  Therapeutic tumor vaccine: At present, a tumor vaccine for prostate cancer has been marketed in the United States, and several therapeutic products are in the clinical trial stage.

  Since therapeutic tumor vaccine is aimed at tumor patients and is therapeutic, why is it also called vaccine?

  Li Hangwen, founder and CEO of Microorganism, a leading domestic tumor vaccine company, explained to the reporter of Science and Technology Daily that "tumor vaccine is actually a kind of immunotherapy. For example, we use mRNA to express tumor antigen. Tumor antigen is like a marker (wearing a red hat), which will remind and mobilize the police (immune system) to catch thieves, and the person wearing a red hat is a thief. Therefore, the immune system can find the thief according to the red hat and then attack the tumor. "

  Because the principle that "portrait" makes the immune system know about tumor is consistent with the principle of vaccine, this immunotherapy method is also called "tumor vaccine".

  "This is different from the way in which chemical drugs and antibody drugs introduce foreign aid. Tumor vaccines completely rely on the immune response generated by the human body to eliminate tumors. " Li Hangwen said that once immunotherapy is effective, it will generally not produce drug resistance, and the immune system will "intelligently follow up" until the tumor is beaten. Moreover, immunotherapy will produce immune memory, and when the human body encounters the same pathogen attack again, it will quickly produce immune response and eliminate the pathogen. With traditional methods, it is easy to produce drug resistance, and the tumor will "wander". If it recurs, it may be more dangerous.
