How does the history of the Party describe the process of smashing the Gang of Four？

　　　　　[Editor’s note]

　　　　 The 48-episode TV series "Deng Xiaoping at a turning point in history" was officially launched on CCTV 1 on August 8, which triggered a heated discussion among netizens. The drama broadcast that day involved the plot of smashing the Gang of Four. The Paper specially excerpted the relevant contents about this matter in the book History of communist party in China.

In October 1976, people from all walks of life in the capital gathered and marched, cheering and smashing the victory of the Gang of Four.

Hua Guofeng was aware of the danger of the Gang of Four usurping the Party.

　　　　　　　　After the death of Mao Zedong, the Gang of Four stepped up their conspiracy to seize the supreme leadership of the Party and the state. While Mao Zedong was seriously ill, in late August, the gang of four’s best friend in Shanghai suddenly distributed weapons and stepped up the equipment of Shanghai militia, firing 74,220 guns, 300 guns and more than 10 million rounds of various ammunition in an attempt to make Shanghai a base for them to seize the highest power. After Mao Zedong’s death, their conspiracy became even more unbridled. On September 11th, Wang Hongwen set up another duty room in Zhongnanhai instead of the duty room of the Central Office, and informed the party committees of all provinces, municipalities and autonomous regions that major issues should be reported to them in a timely manner in an attempt to cut off the contact between the CPC Central Committee and all localities and command the whole country by them. Jiang Qing tried her best to master the documents and materials kept by Mao Zedong. The Gang of Four also monitored Hua Guofeng’s actions. They secretly made many arrangements for Shanghai’s cronies. The Gang of Four manipulated some people in Tsinghua University, Peking University, Xinhua and other units to write "loyalty letters" and "persuasion letters" to Jiang Qing. Some people openly asked Jiang Qing to "serve as Chairman the Central Committee of the Communist Party of China and Chairman of the Military Commission" and "shoulder this heavy burden". Wang Hongwen made a standard portrait ready to be hung in the whole country, and ordered the literary and art circles to shoot films such as "Grand Festival".

　　　　　　　　As the first vice-chairman of the CPC Central Committee and presiding over the work of the Central Committee, Hua Guofeng was aware of the serious danger of the Gang of Four usurping the party and seizing power, and thought that it was necessary to urgently seek countermeasures to remove this gangrene from the body of the party and the state. On September 11th, Hua Guofeng went to Li Xiannian’s residence and said: The struggle against the Gang of Four is inevitable, and now it’s time to solve it. Hua Guofeng also asked Li Xiannian to go to see Ye Jianying on his behalf and ask Ye Jianying for advice on how and when to solve the problem of the Gang of Four. On September 14th, Li Xiannian went to Ye Jianying’s residence, conveyed Hua Guofeng’s opinion and studied the matter with him. After repeated studies with Ye Jianying, Li Xiannian and Wang Dongxing, Hua Guofeng thought that the struggle against the Gang of Four was deadly and beyond the scope of normal inner-party contradictions and struggles, and decisive measures should be taken to solve them, but it was also necessary to avoid causing major social unrest.

　People’s Daily published forged dying entrustment.

　　　　　　　　In order to create public opinion for coming to power, the Gang of Four forged a so-called dying order from Chairman Mao, which was "to follow the established policy". On September 16th, People’s Daily, Red Flag magazine and People’s Liberation Army Daily published editorials saying: "Chairman Mao enjoined us to’ follow the established policy’." "To follow the established policy is to follow Chairman Mao’s proletarian revolutionary line and various policies." They took "following the established policy" as the propaganda center at that time, occupied the main page in newspapers and periodicals, repeatedly publicized, raised themselves and attacked Hua Guofeng and others.

　　　　　　　　The Gang of Four forged Mao Zedong’s dying "orders", which aroused Hua Guofeng’s greater vigilance. Compared with the three sentences written by Mao Zedong more than four months ago, on October 2, Hua Guofeng corrected this formulation in the "Speech by the Head of the China Delegation at the 31st Session of the United Nations General Assembly" submitted for review, and instructed: I checked it correctly, and I made three mistakes with Chairman Mao’s handwriting. What Chairman Mao wrote and what I conveyed to the Politburo were "to follow the past policy". In order to avoid further misinformation, I deleted it. However, Zhang Chunqiao instructed in this document: "The proposal will not be issued." Jiang Qing agrees with Zhang Chunqiao. On the one hand, the Gang of Four blocked the issuance of Hua Guofeng’s instructions to prevent the fraud of forging Mao Zedong’s dying "instructions" from being exposed; on the other hand, they instructed their writing team to concoct another article with a higher tone of "following the established policy". On October 4th, Guangming Daily published "Liang Xiao" article "Always Follow Chairman Mao’s established policy". The article said: "To tamper with Chairman Mao’s established policy is to betray Marxism, socialism and the great theory of continuing revolution under the dictatorship of the proletariat." "Any revisionist leader who dares to tamper with Chairman Mao’s established policy will definitely come to no good end." The article is directed at leaders such as Hua Guofeng who presided over the central work.

　　　　　　　　Around this time, the activities of the Gang of Four conspiring to usurp power were even more explicit. On October 1st, Jiang Qing made a speech in Tsinghua University, warning everyone: "There will be someone who will reverse his conviction for him", and said: "I also want to swear to you young people that you must exercise well and fight with them. Class struggle and line struggle are still long." On October 3rd, when Wang Hongwen spoke in Pinggu County, Beijing, he declared: "The Central Committee has revisionism. What will you do? Down! " "There may be Tang Xiaoping, Wang Xiaoping and the like in the future, so be alert!" "Look at revisionism with your eyes wide open."

The older generation of revolutionaries turned the crisis around

　　　　　　　　Ye Jianying, Li Xiannian and many other revolutionaries of the older generation were deeply worried by the activities of the Gang of Four to usurp the party and seize power. Most of them are in a difficult situation, but they still exchange information through various channels and forms, put forward suggestions to reverse the crisis, and brew solutions to the problem of the Gang of Four. Hua Guofeng, Ye Jianying, Li Xiannian, Wang Dongxing and others, after careful consideration and repeated discussions, and with the consent of most comrades in the Political Bureau of the Central Committee, decided to take measures to isolate and censor the Gang of Four.

　　　　　　　　At 8 pm on October 6, Hua Guofeng and Ye Jianying convened a The Politburo Standing Committee (PSC) meeting in Huairentang, Zhongnanhai, and informed Yao Wenyuan to attend. When Zhang Chunqiao, Wang Hongwen and Yao Wenyuan arrived in the conference room successively, they announced that they would be quarantined for review. At the same time, send someone to Zhongnanhai Jiang Qing’s residence to announce the implementation of the same decision. The evil gang of four was smashed in one fell swoop. At the same time, the Party Central Committee sent people to take over the central propaganda organizations controlled by the Gang of Four, such as Xinhua News Agency, china national radio and People’s Daily. At 10 o’clock that night, the Central Committee of the Communist Party of China held an emergency meeting of the Political Bureau, decided to smash the major issues of the party and the country after the Gang of Four, and unanimously passed the resolution that Hua Guofeng was appointed as Chairman of the Central Committee of the Communist Party of China and Chairman of the Central Military Commission (to be ratified by the Third Plenary Session of the Tenth Central Committee of the Party).

　　　　　　　　From October 7 to 14, the Political Bureau of the Central Committee held a greeting meeting in batches in Beijing attended by the central party, government and military organs, the heads of provinces, autonomous regions, municipalities directly under the Central Government and major military regions, and reported the decisive measures taken against the Gang of Four and the resolution of the CPC Central Committee on Hua Guofeng’s appointment as Chairman of the Central Committee of the Communist Party of China and Chairman of the Central Military Commission. The meeting exposed the conspiracy and crimes of the Gang of Four to usurp the party and seize power, arranged the important work of the party and the state after the downfall of the Gang of Four, and determined the policy of both solving problems and stabilizing the situation. On October 8th, the Central Committee of the Communist Party of China made two decisions: First, establish a memorial hall for President Mao Zedong in Beijing, and move the crystal coffin containing Mao Zedong’s body into the hall, so that the masses can pay tribute to his remains. Second, publish the fifth volume of Selected Works of Mao Zedong as soon as possible, and prepare for the publication of The Complete Works of Mao Zedong.

Disintegrate the armed rebellion in Shanghai in advance

　　　　　　　　After the backbone of the Gang of Four in Shanghai found out that Jiang Qing and others had been quarantined and censored, they immediately mobilized urgently in an attempt to launch an armed rebellion. They organized the command team, mobilized the militia, used a variety of guns and vehicles, concentrated a lot of materials and food, and deployed specific steps of armed rebellion, preparing for a final struggle to save Jiang Qing’s counter-revolutionary group. They are also going to publish a letter to the people of the whole city, and put forward slogans such as "Give me back Jiang Qing, give me back the Spring Bridge, give me back Wen Yuan and give me back Hong Wen". The Central Committee of the Communist Party of China anticipated the problems in Shanghai and took effective measures in time to control the situation in Shanghai. The plot of Jiang Qing’s counter-revolutionary group to launch an armed coup collapsed in an instant. After the plot of Jiang Qing’s counter-revolutionary group to instigate an armed coup in Shanghai was shattered, the people of Shanghai denounced the Gang of Four and swept the city.

　　　　　　　　On October 18th, the Central Committee of the Communist Party of China issued the "Notice on Wang Hongwen, Zhang Chunqiao, Jiang Qing and Yao Wenyuan’s Anti-Party Group Events" to the county-level party organizations, informing them of the crimes of the Gang of Four and Mao Zedong’s criticism of them since February 1974, calling on the whole party to unite closely and launch a struggle to expose and criticize the Gang of Four, and hoping that comrades who made mistakes, including serious mistakes, would wake up as soon as possible. The "Notice" also emphasizes: in the struggle, we should pay attention to policies, expand the scope of education, narrow the scope of attack, and treat people who make mistakes differently; The struggle against the Gang of Four is always carried out under the leadership of Party committees, and effective measures should be taken to eliminate factionalism.

“举国上下一片欢腾”

　　　　　　　　粉碎“四人帮”的消息一经公开，全国各族人民欣喜若狂，举国上下一片欢腾。从10月21日至30日，全国29个省、市、自治区和人民解放军各部队举行盛大集会和游行，拥护党中央粉碎“四人帮”的果断措施，庆祝粉碎“四人帮”的重大胜利。工人、农民、解放军和学生代表纷纷发言，称颂粉碎“四人帮”是为党锄奸，为国除害，为民平愤。21日，首都北京150万军民举行声势浩大的庆祝游行。从清晨开始，一队又一队各界群众高举红旗，敲锣打鼓，从四面八方涌向天安门广场。天安门广场上红旗如林，歌声、锣鼓声、鞭炮声、口号声响成一片。人们载歌载舞，开怀畅饮，很多大中城市的烟花爆竹销售一空，大小商店的酒柜前排起了长队。有30多个国家和地区的电视台收录并播放了首都百万群众在天安门广场举行庆祝大会的实况。香港、澳门各界爱国同胞也举行了庆祝集会。关心祖国命运的海外华侨欢欣鼓舞，表示“心中的一块石头落了地”。

　　　　　　　　Crushing Jiang Qing’s counter-revolutionary clique is a struggle carried out by the Political Bureau of the Central Committee in a special way under the extraordinary situation by carrying out the will of the Party and the people. This is a great victory achieved by the long-term struggle of the whole party, the whole army and the people of all ethnic groups throughout the country. Hua Guofeng, Ye Jianying and Li Xiannian played an important role in the struggle to crush Jiang Qing’s counter-revolutionary clique. The crushing of Jiang Qing’s counter-revolutionary clique realized the common will of the Party and the people, saved the Party, the country and the socialist cause in China from the crisis, and created the premise for realizing the great turning point of the Party’s history.

　　　　　　　　Jiang Qing and others pushed the "Left" mistakes to extremes in the "Cultural Revolution" and committed countless crimes. From November 1980 to January 1981, Lin Biao and Jiang Qing, two counter-revolutionary groups that caused disasters to our country and nation during the "Cultural Revolution", were prosecuted by the the Supreme People’s Procuratorate Special Prosecutor’s Office and tried in public by the the Supreme People’s Court Special Court. The trial of two counter-revolutionary groups, Lin Biao and Jiang Qing, according to law is of great significance for the political life of the party and the country to turn into the legal track, and has achieved a historic turning point in restoring and rebuilding China’s judicial system.(History Research Office of the Central Committee of the Communist Party of China: History of communist party, Volume II (1949-1978), History of the Communist Party of China Press, January 2011)　

The latest progress in AIDS treatment is expected to rewrite the future treatment pattern.

Original Lingjun medical field

The study once again suggests that monoclonal antibody combined therapy is one of the most promising methods to completely cure AIDS.

On June 1, 2022, the top magazine Nature published a heavy research on AIDS treatment.

In the experiment, as an alternative therapy to conventional antiretroviral therapy (ART), the HIV level in the infected person was controlled for up to 43 weeks after the combination of two broad-spectrum neutralizing monoclonal antibodies.

Researchers believe that in the future, HIV-infected people may not need ART treatment every day, but only need low-frequency (such as biennial) medication, and perhaps combined with long-acting antiretroviral drugs, they can return to normal life.

Based on this research, Professor Lu Hongzhou, Dean of the Third People’s Hospital of Shenzhen, told the "medical field" that monoclonal antibody combination therapy is one of the most promising methods to completely cure AIDS. "At present, many studies have shown that low-frequency use of monoclonal antibody combination therapy can effectively maintain virus inhibition, but the virus will rebound after stopping drug use. It is expected to change this situation by further screening and developing long-acting monoclonal antibodies."

High level of HIV inhibition

Up to 43 weeks

Today, 40 years later, AIDS is no longer a "terminal disease".

With the advent of "highly effective antiretroviral therapy" (HAART), that is, cocktail therapy, the virus level in HIV-infected people has been effectively controlled, even reaching "non-infectious" in clinical indicators, and the life expectancy is close to that of ordinary people.

But the defects are also obvious. HIV-infected people need to take medicine every day and for life, and their compliance varies from person to person. Once the drug is stopped, the virus level in the body will rebound quickly. In addition, lifelong use of drugs may have long-term side effects and create the possibility for the emergence of drug-resistant viruses.

This time, the researchers conducted a small phase I clinical trial, and tested the combination therapy of two monoclonal antibodies, 3BNC117 and 10-1074, which are aimed at different targets, and are expected to bring a breakthrough in "long-term treatment".

The trial is divided into two parts. The first is a randomized, double-blind, placebo-controlled study involving 14 infected people. They first received antiretroviral therapy (ART), then stopped taking drugs and received up to eight times of "monoclonal antibody combination therapy" or placebo-twice in the first month and once a month thereafter.

The results showed that, except one infected person who secretly recovered ART for fear of illness, the HIV levels of the other six placebo subjects all rebounded 28 weeks ago, and ART treatment must be restarted immediately, with a median time of 9.4 weeks.

All 7 people in the monoclonal antibody combined treatment group did not need to restart ART. Five of them showed a very high level of HIV viremia inhibition, and the effect lasted for up to 43 weeks, that is, 19 weeks after stopping the "monoclonal antibody combination therapy".

However, it is worth noting that in the second part of the experiment, the researchers recruited another five HIV-infected people who had not received ART. After the start of "monoclonal antibody combined therapy", only two people achieved complete inhibition of HIV, and the average duration was 41.7 weeks.

Further research found that the other three infected people whose virus levels were not controlled were resistant to two kinds of monoclonal antibodies.

The same findings also appeared in the first trial. Although there was no need to restart ART treatment in the treatment group, two people had a partial rebound in virus level in the first 8 weeks, which was also due to the existence of drug-resistant viruses in the body.

The researchers pointed out, "This suggests that the premise of treatment is that there can be no virus resistant to the corresponding monoclonal antibody in the infected person before administration.

Can we finally realize the "clinical cure" of AIDS?

This is not the first time to study the treatment of AIDS with 3BNC117 and 10-1074.

As early as 2018, the team of Professor Nussenzweig from Rockefeller University published a paper in Nature: After stopping ART, using this monoclonal antibody combination can effectively inhibit HIV for 15-30 weeks (median 21 weeks).

"They can inhibit HIV in infected people for several months, and may produce new methods to prevent and treat AIDS." In 2020, Rockefeller University published a document in official website, and the antibody combination has been acquired by a large multinational pharmaceutical company in the United States.

On April 13th, 2022, Professor Nussenzweig and his team updated the research progress again. All the infected people who received the combination therapy of the monoclonal antibody for 7 times still maintained virus inhibition within 21 to 48 weeks after stopping the injection.

Professor Lu Hongzhou told the medical community that monoclonal antibody therapy has been widely studied and applied in the field of HIV prevention and treatment in recent years, and it has been proved that it can inhibit HIV-1 infection in animal models for several years.

"The breakthrough significance of the latest research is that it is further confirmed that the combination therapy of broad-spectrum neutralizing monoclonal antibody can inhibit the virus level in human body for a long time, and it shows good safety and tolerance, which is expected to become an alternative to daily ART." Professor Lu Hongzhou said.

However, combined with the latest research, Professor Lu Hongzhou said that there are still some problems to be solved urgently.

First of all, the combination therapy of monoclonal antibodies needs to screen HIV drug resistance in the infected person in advance, and the sensitivity test for monoclonal antibodies requires high test technology itself, which may limit the popularization and application of this therapy.

"HIV virus has a high frequency of mutation and a variety of immune escape strategies, and the problem of drug resistance can not be ignored. Therefore, it is also the key to develop effective extended-spectrum neutralizing antibodies and jointly identify monoclonal antibodies against different targets of the virus in the future." Professor Lu Hongzhou said.

Secondly, the study mentioned that although it is expected to greatly reduce the frequency of drug use (only twice a year), in the current course of 8 doses, once the drug is completely stopped, the virus level will eventually rebound.

"Whether the infection process can be completely changed, that is, whether the virus can be suppressed for a long time after stopping the drug, needs to be finally solved and evaluated by increasing the previous course of treatment and extending the follow-up time." The researchers said.

Professor Lu Hongzhou believes that whether "long-acting monoclonal antibody combination" can help HIV-infected people to suppress the virus in their bodies for a long time (such as several years) and achieve the final "clinical cure" by clearing the HIV virus repository still needs longer-term clinical data to support.

The first pilot demonstration project of land greening in Xinjiang Autonomous Region and Production and Construction Corps was opened.

　　CCTV News:A few days ago, the Ninth Division of Xinjiang Production and Construction Corps set off a nationwide tree planting craze. Different from previous years, this year’s "project tree" was planted.

　　In 2022, the pilot demonstration project of the ninth division’s land greening organized by the Finance Bureau of the Corps and the Forestry and Grassland Bureau of the Corps passed the competitive evaluation and won the support of 200 million yuan from the central government for forestry reform and development. This is the first time that the autonomous region and the Corps have successfully applied for the national land greening pilot demonstration project.

　　It is reported that this project, combined with the overall objectives of the Corps and the Ninth Division’s "Tenth Five-Year Plan" development plan, based on the landscape pattern and resource advantages of the Ninth Division, has planted Ulmus pumila, Populus alba, Elaeagnus angustifolia, Hippophae rhamnoides and other measures in more than 3,600 plots of 91 companies in 10 regiments in the whole division through artificial afforestation, artificial grass planting, restoration of degraded forests, closing hillsides to facilitate afforestation, forest tending and restoration and treatment of degraded grasslands.

　　Wang Zhonghua, director of the Natural Resources and Planning Bureau of the Ninth Division, said that the implementation of this project will continuously improve the regional ecological environment quality, significantly enhance the ecological carrying capacity, increase the forest coverage rate by 0.26 percentage points, and increase the grassland comprehensive vegetation coverage rate by 0.4 percentage points, which is of great significance for restoring and improving the regional ecological environment in the northwest border areas, enhancing the growth potential of forest and grass carbon sinks, and achieving a win-win situation in social, economic and ecological benefits.

　　In order to promote the project construction with high quality and high standard, the Ninth Division set up a project work coordination group, established an organizational system in which the main leaders of the Party and government take overall responsibility, the relevant departments perform their respective duties and are responsible for division of labor, scientifically formulated a greening plan, improved the project fund use system, and decomposed the project construction into specific implementation units according to the principle of territorial responsibility according to the year and region. At the same time, the Implementation Plan for Full Implementation of Forest Length System in the Ninth Division was issued, and a three-level forest length system was established at division, regiment and company levels.

　　At present, according to the principle of "one group, one product", all regimental farms organize enterprises, cooperatives and workers to participate in the construction, and plan to complete the tree planting work by the end of April. (Reporter Yan Huimin)

From the annual sales of 60,000 yuan to 5 million yuan, the ＂online celebrity＂ village has sold more than 100,000 kilograms of agricultural products.

　　Xinnian Wang sells local specialties live on the Internet in Alibaba Village, Dongxiang District, Fuzhou City, Jiangxi Province.

　　Every morning, Wang Xinnian of Shangchi Village, Liwei Town, Dongxiang District, Fuzhou City, Jiangxi Province, starts a live webcast, selling agricultural products such as brown sugar that the villagers have just made. After this simple and honest young man succeeded in starting his own business, he did not forget the villagers and led them to "touch the net" together, so that agricultural products could "fly" from the internet to all parts of the country. In 2018, he was named "China Rural E-commerce Rich Leader" by the Organizing Committee of China Rural E-commerce Conference.

　　Wang Xinnian, born in 1976, is a native of Shangchi Village. After leaving the army, he started his business abroad for nearly 20 years. In 2014, he returned to the village, opened online stores on platforms such as Taobao, Weidian and Maile.com, operated e-commerce poverty alleviation stations, and established agricultural product planting cooperatives. Through the "internet plus Cooperative+Farmers" model, hundreds of villagers joined the cooperatives and insisted on 10% higher than the market price & mdash; At the price of 20%, we will buy agricultural products such as Dictyophora, Dried Plum Vegetables and Handmade Brown Sugar planted and produced by poor households and old, weak and low-income groups in the surrounding areas to help poor households increase their income and get rich.

　　"At first, they didn’t believe that agricultural products could be sold online. Now it has become a habit to sell things online, and some of them also do live broadcasts with me!" In order to help more farmers "touch the net", Xinnian Wang has provided free e-commerce training for more than 400 farmers in the whole region. Today, Xinnian Wang has become a local "online celebrity" village broadcaster. Driven by him, several farmers have followed him to do e-commerce, and live broadcast at the head of the village in the field has become a new fashion for local farmers.

　　Wang Xinnian’s e-commerce poverty alleviation station has increased from the first year’s e-commerce sales of 60,000 yuan to the current annual sales of more than 5 million yuan, and the accumulated sales of agricultural products have exceeded 100,000 kilograms.

Tesla driving data can be seen by spending money. What is the $1,200 EDR suite？

Editor’s Note: This article comes from WeChat WeChat official account "Chedongxi" (ID:chedongxi), and is published by 36Kr with authorization.

Edit | Han Xiao

In the face of frequent out-of-control doubts, Tesla finally gave a powerful counterattack-began to disclose the "black box" data of the vehicle to the owner.

Just a few days ago, Tesla launched the EDR data extraction kit in the United States and official website, with a price of $1,200 (about 7,768 RMB).

The full name of EDR is Event Data Recorder, which can record the data related to vehicle dynamics and safety system in a period of time, including vehicle speed, steering wheel angle, whether the seat belt is fastened and so on.

With the driving data recorder, people will have the opportunity to restore the vehicle state before the accident as truly as possible, so as to explore the cause of the accident, which is called Tesla’s "black box".

This data extraction kit includes all the hardware needed to extract the data. After purchasing the kit, the owner needs to download the Tesla EDR data extraction program and register the MyTesla account to obtain the data and export it as a PDF file.

In the last year or two, rumors that Tesla is out of control have been frequently exposed in major media, and the radical rights protection behavior at the Shanghai Auto Show has pushed Tesla to the forefront.

But unfortunately, at present, a few rights-defending car owners and Tesla hold their own words, and the investigation results of authoritative organizations have not yet been announced, making Tesla’s out-of-control incident a Rashomon sweeping the world.

With Tesla starting to sell EDR kits, consumers, third-party organizations and regulatory authorities can read the vehicle data themselves to restore the truth. I believe that this "Tesla out of control storm" that has been raging is about to subside.

This EDR data extraction kit is introduced by CrashDataGroup, which includes hardware such as in-vehicle cables, USB PCAN communication cables, D2M cables, etc., and is protected by hard-shell boxes outside.

A suite contains all the hardware needed to export EDR data, and the price is $1,200 (about 7,768 RMB), which is $334 (about 2,162 RMB) lower than the total price of all the hardware sold separately.

Because different Model S manufactured at different times require different hardware, CrashDataGroup will adjust the hardware configuration according to the information provided by the owner. At present, the kits they provide can be adapted to each model of Model S, Model X, Model 3 and Model Y.

In addition, Tesla Roadster, which was shipped from 2008 to 2012, was not equipped with EDR driving data recorder. CrashDataGroup did not launch a data extraction kit for this model, but introduced two other data extraction methods for the owners.

After purchasing the kit, the owner also needs to download the Tesla EDR data extraction program and register the MyTesla account. The good news is that downloading programs and registering accounts are free. Then the owner can access and retrieve the data and export the data records in PDF format.

CrashDataGroup, which launched the data extraction suite, provided some samples of EDR records, which showed what people finally saw in PDF files.

Taking Model 3 described in the sample as an example, assuming a collision occurs, EDR will record the vehicle body state data such as the vehicle speed at the moment of collision, the lateral and longitudinal accelerations, the time taken to reach the maximum acceleration, and also record the human operation data such as which seats are occupied and whether the seat belts are fastened.

If people want to know more about what happened at the moment of collision, they can refer to more data recorded by EDR. For example, the table of vehicle speed, accelerator pedal opening and motor speed within 5 seconds before collision. If the accelerator pedal opening increases sharply and the motor speed and speed also increase in a period of time before the collision, then the driver is likely to step on the accelerator as a brake.

The example shows that the driver only slightly stepped on the accelerator pedal 2.4 seconds before the collision (the pedal opening is 4.8%), and the motor speed and speed also gradually decreased, which shows that the driver did not mistake the accelerator as a brake.

As for the braking system, the driver stepped on the brakes intermittently for three times within five seconds before the collision. 4.5 seconds before the collision, the driver stepped on the brake for the first time, probably because the pedaling duration was too short and the ABS anti-lock braking system did not intervene.

Then the driver stepped on the brake for the second time between 3.0 seconds and 2.5 seconds before the collision, and the ABS system intervened, but it didn’t seem to work in time.

From 1.5 seconds before the collision to the moment of the collision, the driver stepped on the brake for the third time, and the ABS system successfully intervened and played a role, but unfortunately the collision could not be avoided.

In addition, the car body stabilization procedure is in an intervening state.

It can be seen that for some reason, the driver failed to step on the brake pedal at the first time. The authoritative department can make further investigation according to EDR records to dig deep into the cause and effect of the accident.

In recent one or two years, rumors of Tesla losing control frequently broke out in China. Among them, the rumor of brake failure is probably the most common and the most frightening one, and examples of steering failure and charging failure are not uncommon. In the face of doubts and even accusations, Tesla has always said that there is no problem with its products, and the causes of accidents are human error by drivers or failure of charging facilities.

The radical rights-defending behavior at the Shanghai Auto Show pushed Tesla to the forefront of public opinion. However, the rights-defending car owners and Tesla officials have always held their own words and refused to give in, and the state authorities have not given a clear answer for the time being.

With the passage of time, perhaps out of dissatisfaction with Tesla’s secretive and frequent throwing of pots, people gradually stopped focusing on whether the brakes failed, but began to argue whether Tesla cut corners and whether Tesla could be responsible for the lives and property of consumers in China.

This can’t be entirely blamed on China consumers. With the continuous expansion of the automobile market in China, consumers in China have a deeper understanding of automobile products and automobile industry, and the requirements for comprehensive quality of vehicles, especially safety, are bound to increase rather than decrease.

If Tesla wants to prove that there is nothing wrong with the safety of his vehicle, it is a good way to prove his innocence by making the driving data public.

With the driving data as the basis, the owner can find out the cause of the accident more easily. For traffic control departments and insurance companies, the process of traffic management and insurance responsibility can also go faster. If there is a problem with Tesla vehicles, the practice of disclosing data can also reflect Tesla’s sense of responsibility and win a wave of praise, which is also a wake-up call and spur for Tesla itself.

More importantly, public data can calm people’s hearts and make rumors self-defeating.

For example, in an accident once reported by Chedong, EDR data helped the owner to find the real cause of the accident and let the insurance company complete the accurate insurance liability.

The story took place in the United States. A driver driving a Tesla car shuttled through a narrow and tortuous parking garage, and crashed into other innocent vehicles at a downhill turn, and one of them was even pushed through the wall.

Afterwards, Dai Dai insisted that the accidental acceleration caused by the forced takeover of the intelligent driving system led to the accident. However, after the owner retrieved the data left by the EDR driving data recorder, he found that there was something hidden.

The data shows that the driver realized that he needed to step on the brakes to slow down from 0.8 seconds before the collision, but the accelerator pedal pedaling stroke increased sharply due to misoperation, and he stepped on the floor oil from 0.4 seconds before the collision to the collision position. At the same time, within 5 seconds before the collision, the driver did not step on the brake pedal. In addition, the careless driver didn’t fasten his seat belt all the way.

Obviously, the driver mistakenly used the accelerator as a brake, and this accident was caused by human error of the driver.

Admittedly, it is gratifying that the owner can get the EDR data and then restore the truth, but the process of obtaining the data by the owner is not smooth sailing. He first contacted Tesla officials to ask for EDR data records, but Tesla said that he refused to provide them because he did not live in California. After the owner’s appointed lawyer contacted Tesla, the technicians charged $1,300 before handing over the EDR data to the owner.

Now, with the EDR data extraction kit, other people can access and retrieve EDR records without spending too much time and money if they encounter a situation similar to that of this car owner, and export the data as a PDF file for evidence in court.

Unfortunately, this kit is only sold in the United States and Canada for the time being. However, Che Dongxi asked the Tesla official, and the other party said that the data extraction kit suitable for China Tesla models is under development and will be listed as early as this year.

Tesla EDR data extraction kit includes all the hardware needed to read and retrieve driving data, and can adapt to most models of Tesla, which is a very convenient tool for Tesla owners.

This tool can enable car owners to obtain driving data in a shorter time and at a lower cost, and will be used as objective evidence in traffic management and insurance liability determination, which will help to highlight the fairness and justice of road law enforcement.

With the synchronous development of China automobile market and national automobile industry, consumers in China have a deeper understanding of automobile products, and the demand for vehicle safety has only increased. At this time, however, a radical act of safeguarding rights made "Tesla’s brake failure" a hot topic of discussion among the whole people, and the state authorities failed to give an answer for the time being.

If this kit can be put into use in large quantities in China, the driving data will become more transparent, and some rumors about Tesla will surely be broken.

Finally, it should be pointed out that no matter what the vehicle itself is, people’s safety concept should not be relaxed. In addition to venting personal anger, what deserves people’s attention most is how people cooperate with technology to improve traffic safety together, rather than arguing whether the technology itself is perfect.

After further in-depth investigation, they planned to choose appropriate ways to give publicity and reports to further help the construction of campus psychological services.

Science education is based on inquiry.

Science education for primary and middle school students should conform to children’s cognitive characteristics, care for their innate curiosity and imagination, and help them appreciate the wonderful fun of observing, thinking and experimenting like scientists.　　　　

Although there are many opinions on how to add science education in the "double reduction" of education, there is a consensus that strengthening science education is not only to increase the teaching of scientific knowledge, but also to cultivate scientific literacy. Scientific literacy has the characteristics of multi-factor and multi-dimensional organic integration, including not only scientific knowledge and methods, but also scientific thinking, scientific attitude and scientific spirit. From the perspective of education, every subject, every scene and every link related to literacy cultivation cannot be separated from inquiry. Whether it’s questioning, model building, hypothetical experiment, problem solving, system discovery, innovation and development … The whole process of exploring with the germination, jointing, flowering and results of scientific literacy is filled in the life experience of every subject of science education. It can be said that science education is alive and smart because of inquiry. Facing the future, science education for teenagers should be based on inquiry.

As a biological term, "root" is an important organ of plants, which is mainly responsible for absorbing water and minerals, fixing plants and storing nutrients. Its morphological structure can be changed according to plant species and growth environment. In the Chinese culture, which highly values understanding things, "root" has long gone beyond its original meaning and has multiple meanings such as root, root, root cause and basis. No matter how complicated and ever-changing things are, only by nourishing their roots and guarding their foundations can they be deeply rooted and endless. Science education for primary and middle school students should conform to children’s cognitive characteristics, care for their innate curiosity and imagination, and help them appreciate the wonderful fun of observing, thinking and experimenting like scientists. Only in this way can the seeds of scientific innovation take root in their hearts and grow wantonly, and then become a habit and a state of life. Inquiry is not only a way of learning, but also a scientific attitude, and it is also an innovative quality, which indicates that learners gain happiness, satisfaction and sense of accomplishment in learning, scientific research and creation through self-attempt, thus laying a solid foundation for lifelong enthusiasm for scientific exploration. Inquiry is of great value to science education. The inquiry characteristics of science education are fully demonstrated in a multi-level sense.

One is the premise of the experiment. Experiments in science education must be based on inquiry. Without the examination and discussion of phenomena and previous experience, the birth of research problems lacks cognitive basis and theoretical basis. Inquiry, as the premise of experiment, is often manifested as questioning and questioning. In the process of questioning and questioning, everyone can express their opinions and brainstorm, so that new ideas can be generated and the experimental direction can be clarified. As the saying goes, "the trace of suspicion must be observed", only by finding the driving problem that is really worth exploring and investigating, and roughly clarifying the ins and outs, can we preset the solution to the problem and start the scientific experiment pointing to new discoveries and inventions. Science education is guided by questions, and starts from questioning and exploring.

The second is the learning content. Inquiry does not lie in science education, but stays at the entrance of science education, but advances with science education and becomes a part of science education content. Because the purpose of science education is to "guide students to participate in inquiry practice extensively, combine learning with thinking, entertain and entertain, consciously acquire scientific knowledge, cultivate scientific spirit, improve scientific quality … and weave the dream of becoming a scientist". Guiding students to think, explore and solve problems like scientists is the natural move and practical action of science education.

The third is the way of thinking. If inquiry, as an experimental premise or learning content, is separated from science educators to some extent, then from the perspective of thinking mode, inquiry is really integrated into teaching wisdom. In the design of science education teaching scheme, teachers’ inquiry thinking can’t be absent. On the basis of insight into the learning situation and analysis of problems, teachers can correctly preset various problems that may occur in the experiment and explore solutions. Only in the process of implementation can they meet the river and bridge the ladder, leading students to the other side of science. As the saying goes, "those who teach, grow good and save those who lose", "what is done above, what is done below". When teachers implement science education with inquiry thinking, students will acquire inquiry thinking through immersion experience.

The fourth is the necessary character. The cultivation of scientific literacy is indispensable to interrogation and reflection on existing cognitive schemes and investigation and identification of existing facts. It is an essential feature and character of science education to bring interrogation, reflection and investigation into the thinking process and integrate it into the content of science education. In other words, inquiry is the internal need of the implementation of science education and the driving force for the promotion of science education. Without inquiry, there is no real science education; If we don’t plant the roots of inquiry, it will be difficult to see the effectiveness of science education.

Inquiry contains the spirit of reflection, experiment and identification, which has both negative actions and constructive pursuit. Exploration in a complete sense is the dialectical unity of cracking and constructing, denying and affirming, keeping right and innovating. Healthy, active and scientific exploration should strive to achieve the unity of the following aspects.

The first is the unity of scientific inquiry and value inquiry. Scientific inquiry is an inquiry based on facts, in order to pursue the truth and help to establish the truth. It combs and examines the existing cognition and scheme based on the facts or conditions that have been presented, so as to reveal the essence of things and find the law of things’ operation under the conditions of teaching experiments. Value inquiry is an inquiry based on belief, the pursuit of meaning and the establishment of spirit. Based on the value judgment of rejuvenating the country through science and education and cultivating people through virtue, it discriminates and chooses the existing education and teaching ideas, so as to provide direction and adjust the thinking and behavior of teachers and students and clarify the goal of individual growth. The two are not independent, and scientific inquiry contains the content of value inquiry, and value inquiry must also take scientific inquiry as a reference.

The second is the unity of students’ inquiry and teachers’ inquiry. Guiding students to explore and demonstrating existing knowledge and related experiments is an indispensable link and content of scientific literacy cultivation. But at the same time, this process also needs the follow-up of teachers’ inquiry, that is, to constantly revise, enrich and improve their teaching plans and learning scaffolding in response to students’ questions. Students’ inquiry and teachers’ inquiry in science education are closely related. Only emphasizing students’ inquiry while ignoring teachers’ inquiry, science education will inevitably fall into dogma and rigidity, and cannot effectively deal with students’ problems and challenges.

The third is the unity of cognitive inquiry and fact inquiry. The inquiry of science education itself presents as a cognitive inquiry, which includes the doubt and construction of cognition, the exploration and experience of scientific thinking, scientific attitude and scientific spirit, but the inquiry of cognitive concepts cannot be regarded as the whole of science education. Fact inquiry and material inquiry are the transformation, change and innovation of existing things, and their significance is also extraordinary. Although cognitive inquiry is helpful to the transformation of reality, it can’t replace practical strength and material strength after all. Only in fact inquiry, by transforming matter with practice, can the endogenous energy of inquiry be fully released.

Cultivating young people who have the potential of scientists and are willing to devote themselves to scientific research, and laying a solid foundation for building a socialist modern power in an all-round way, can not be separated from the practice and innovation of science education. Science education needs to strengthen the consciousness of inquiry, attach importance to cultivating inquiry thinking, and make inquiry an internal driving force to support students’ lifelong curiosity, continuous exploration and invention.

Traditional customs of the 29 th lunar month

NEW YEAR

Happy the Year of the Loong.

Today is the twenty-ninth day of the twelfth lunar month. On the twenty-ninth day of the twelfth lunar month, the folk customs in different places are different. As the old saying goes, "One steaming, two cooking and three sweeping". So what are these customs on the 29th of the twelfth lunar month? What are the historical origins?

Spring

Festival

Twenty-nine, steamed buns

The folk song "Twenty-nine, Steamed Steamed Steamed Bread", people give full play to their imagination and make steamed bread into various shapes such as peach and small animals. In the past, steamed buns were not made casually, but carefully prepared and carefully, because the steamed buns had to be exchanged with neighbors on blind dates, so they must be made to look good and delicious, which was auspicious and very particular.

In Jiaodong, Shandong Province, steamed buns are to be steamed on the 29th day of the twelfth lunar month, which is as important as wrapping jiaozi in the Lunar New Year’s Eve. No matter how busy you are, every household should steam a few pots. "I made a festive steamed bread last year and made a bigger harvest next year." This is Jiaodong people’s blessing for the New Year. In other areas, steamed flower rolls, bean bags and steamed buns are needed on this day, and several pots of good wine are needed in ancient times.

People in the north steam steamed buns and bean bags on the 29th of the twelfth lunar month, while some areas in the south will make rice cakes on this day. "The whole family, old and young, worshiped and enjoyed eating the rice cake". The rice cake was fragrant, but it was hard to make. First, we selected the best hybrid rice and glutinous rice as the main ingredients, added various ingredients, steamed it, put it in a mortar, and several people took turns pounding it for 15 minutes. When the rice cake became soft and glutinous, it was considered as a success.

Twenty-nine, go get some wine

Spring

Festival

Wine is a symbol of culture in China. In The Book of Rites, it is said that "drinkers support the elderly, so they support the sick." This kind of thing, wine, is the essence of grain. Of course, ancient wine is very different from modern wine, basically like rice wine or fermented grains now; "Yin Ruins Text Category Compilation" said that "the word wine contained in Oracle inscriptions is the name of sacrifice. The archaeologist recommended the ancestral temple when the wine was ripe, and then the son of heaven and his ministers drank it in the DPRK. " The ancients had already started offering sacrifices to their ancestors with wine, which shows that the custom of drinking alcohol in this festival has been circulating for a long time.

On this day, the family went to host a banquet. First, they thanked their neighbors for their usual care, and they were going to keep their old age during the Chinese New Year, one day in advance, and they were respectful. Secondly, on this day, people in the pre-Qin period are already doing this by going to the ancestral graves to welcome their ancestors and offering offerings, imitating the culture of ancient times and inheriting that spiritual sustenance.

Spring

Festival

29,

Go to the grave and ask your ancestors to make a big confession.

The twelfth lunar month is a month for offering sacrifices to ancestors. The Book of Rites says that "the month of Meng Dong, the ancestors of Menlu La were worshipped for five times", and Zuo Zhuan says that "the great event of the country is to worship and conquer". In ancient times, the ancestors of the Central Plains were all agricultural peoples, living and working in peace and contentment, and they were often harassed by nomads. Everyone was trying to survive. This is what Rong said about the north.

In the Han Dynasty, resisting the Huns was a matter of vital importance to the country. Like Rong in Zuo Zhuan, it was to fight to defend one’s homeland. Defending our country and offering sacrifices to our ancestors are equally important in the eyes of our ancestors, which is why China paid so much attention to filial piety culture in ancient times, and now everyone’s inheritance is also such a cultural continuation.

One of the most important aspects of filial piety culture is offering sacrifices to ancestors. Where did it come from without inheritance? The reasons why people worship their ancestors are, firstly, the inheritance of filial piety culture, secondly, not forgetting where they come from, and thirdly, educating future generations and not forgetting the glory and suffering of their ancestors. In future life, we should remember the teachings of our ancestors and avoid many crooked roads.

The lunar calendar in China is divided into big and small months. The big month is 30 days, and the abortion is only 29 days. If the twelfth month is a miscarriage, the 29th is the last day, that is, New Year’s Eve. Everything to welcome the Spring Festival must be ready before this day. In the whole festival, the 29th is the busiest day. In addition, if the twelfth lunar month is a big month, the 29th of the twelfth lunar month is called a small division, that is, the New Year’s Eve is called a big division, that is, the New Year’s Eve.

In many places in the north, the temperature drop may reach 20℃ when the weather changes suddenly on the 15th.

　　Beijing, March 15 (Reporter Zhang Ni) Recently, the rising temperature in most parts of the country made people feel the warmth of spring, and the temperature in many cities even hit a new high this year. However, from today, affected by cold air, the north will usher in a "weather change", and the temperature drop in some places may reach 20 C.

　　The temperature in the north "reverses the daily limit" and Jinan cools down or reaches 20 C.

　　Recently, the temperature in North China, Huanghuai and other places climbed to a new high this year.

　　According to China Weather Network, the temperatures in Beijing, Shijiazhuang, Zhengzhou and other cities all hit new highs this year, while Linzhou (30.6℃) in Henan and Shexian (30.5℃) in Hebei exceeded 30℃, making them the first two cities in northern China to reach above 30℃ this year.

　　On the 14th, the warmth in the north continued. The highest temperatures in Lanzhou and Xining were above 20℃, which was as warm as early May.

　　However, after the warmth reached its peak, the temperature in the north ushered in a "daily limit reversal".

　　The Central Meteorological Observatory issued a forecast on the 14th that in the next three days, the temperature in the central and eastern regions will reverse, and the temperature in the north of the middle and lower reaches of the Yangtze River will drop by 6 ~ 10℃, and the local temperature drop can reach more than 12℃. Some areas in the northwest will also be accompanied by windy and dusty weather. At present, the temperature in the south is high and the unstable energy is sufficient, so it is easy to stimulate strong convective weather when it meets cold air.

　　The reporter observed that there will be a "big diving" of temperature in some cities on the 15th, from spring to winter.

　　For example, according to the data of Jinan Meteorological Bureau, the highest temperature in Jinan reached 27℃ during the day on the 14th, and it will be only 7℃ during the day on the 15th, with a drop of 20℃.

　　In addition, the influence of cold air on North China, Huanghuai and other places will start from the night of 14th, and the temperature will dive sharply on 15th, and the maximum temperature will drop to around 10℃. At the same time, the arrival of cold air will obviously alleviate the low visibility weather that lasts for many days.

　　Data Map: On March 9, 2016, affected by strong cold air, snowfall and cooling weather occurred in many places in Gansu. The picture shows the citizens walking in the snow. Photo by Chen Fei

　　The temperature plummeted, and the "cold spring" came?

　　The attack of cold air makes people feel chilly in spring, so does it mean that the cold spring is coming?

　　The reporter found that the cold in late spring refers to the weather phenomenon that the temperature rises rapidly in early spring (generally refers to the end of February and the beginning of March) and the temperature is lower than normal in late spring (generally refers to April).

　　Long-term rainy weather or frequent cold air invasion, or strong radiation cooling on sunny nights under the control of continuous cold and high pressure, can easily cause late spring cold. The climate in early spring is changeable. If the cold air is strong, the temperature can drop below 10℃, even in rainy and snowy weather.

　　However, the reporter noted that although it has been more than one month in beginning of spring, many areas have not yet entered the meteorological spring.

　　According to the Division of Climatic Seasons, the 5-day moving average temperature based on the current year’s temperature series constitutes a moving average temperature series. When the moving average temperature series is more than 10℃ and less than 22℃ for 5 consecutive days, the first date in the corresponding current year’s temperature series that is more than 10℃ is taken as the start date of spring.

　　According to this standard, many parts of the country, including Beijing, have not yet officially entered the spring, so this cooling can not be called "late spring cold".

　　Why is the weather changeable in spring?

　　The recent temperature "roller coaster" has made people realize what "a child’s face changes three times a day in spring".

　　Why is the weather changeable in spring? In this regard, the meteorological department gave three reasons.

　　First, the atmospheric circulation situation has been adjusted. In spring, the high-altitude westerly circulation affecting China becomes relatively flat, the intensity of the weather system weakens, and the mobility is very obvious. Cold air, like a passer-by, meets with warm air, and jointly staged a series of rainy and snowy weather "short plays".

　　Second, the cold and warm air are evenly matched. In spring, the warm and humid air flow from the ocean is becoming more and more active, and at this time, the cold air is not willing to quit the weather stage. The two are frequently dispatched, and they advance and retreat with each other, staged scenes of spring thunder, rain and snow. Once the rain clears in the south, the temperature will rise again soon.

　　Third, solar radiation began to strengthen. After entering March, the direct point of the sun gradually moved from the south of the equator to the north hemisphere. At this time, the sunshine was stronger than that in winter, but after all, it was not so strong, which made people feel that there was still cold in the morning and evening, and the temperature rose obviously around noon.

　　At the same time, experts also remind the public to pay attention to "spring cover" when it is warm and cold, and adjust their clothes according to the temperature and humidity at that time. The temperature is lower in the morning and evening of spring than at noon, so it is better to wear more clothes than at noon in the morning and evening. When reducing clothes, you should reduce your coat first, then lower your clothes, and pay more attention to keeping your lower body warm. (End)
