Looking back at the dispute between Jun and Wan: In the past 22 years, Wang Shi’s tactics are exactly the same.

In December, 2015, the chairman of Vanke’s board of directors publicly called Baoneng Yao Zhenhua, saying that he was not welcome to become a major shareholder of Vanke, which officially opened the equity battle between the management headed by Wang Shi and Baoneng.

Going back to 1994, Junan Securities, the stock underwriter of Vanke, and a group of shareholders of Vanke, including a new generation of Hainan Securities, demanded the reorganization of Vanke’s board of directors.

The two equity competitions have been worse for more than 20 years, but Vanke’s tactics to stop barbarians are strikingly similar.

First of all, let’s briefly review the battle between Jun and Wan more than 20 years ago.

Jun ‘an camp

Lord:Zhang Guoqing, general manager of Junwan Securities.

Allied forces:Shenzhen New Generation Enterprise Co., Ltd., Hainan Securities, Hong Kong Junshan Investment Co., Ltd., Chuangyi Investment Co., Ltd.

Firepower configuration:It holds 10.73% of Vanke’s total shares.

Purpose of sending troops:Jun ‘an underwritten Vanke B shares, with 10 million shares in hand. The cost price was 12 yuan per share, and the market price was 9 yuan at that time, with a book floating loss of 30 million. The intention is to stimulate the stock price and control the board of Vanke through this acquisition.

Vanke camp

Lord:Wang Shi, Chairman of Vanke Group

Allied forces:Liu Yuansheng, Zhao Xiaofeng and Ma Gongyuan.

Firepower configuration:Actual control right of Vanke’s board of directors

Defense purpose:Repel Junan’s acquisition and protect the stability of Vanke’s existing board of directors.

What happened:On March 30, 1994, according to Wang Shi’s book Road and Dream, Zhang Guoqing, general manager of Junan, entered his office and told him that he would hold a press conference and reorganize in the afternoon, which was only two and a half hours before his official announcement. Wang Shi said that this is a plot for Junwan to take over Vanke in an all-round way.

In response to Jun Wanfang’s aggressiveness, on March 31st, Wang Shi resolutely decided to apply to Shenzhen Stock Exchange for suspension of trading, which was approved-this was the first time that the China stock market was suspended. At that time, there was no suspension restriction on the rise and fall of stocks, and Vanke set a precedent. Wang Shi won time by suspending trading, blocking the "mouse warehouse" of Jun ‘an and others. At the same time, the other shareholders who were wooed by Junan were disintegrated, and the alliance that attempted to reorganize Vanke was disintegrated. Within five days of Jun ‘an’s equity dispute, the war was successfully won.

At that time, in addition to Wang Shi’s strategy, the contacts of Shenzhen government and CSRC were the key to Vanke’s success.

In Wang Shi’s autobiography Road and Dream, there is a description like this:

A week later, Zhang Ziping, director of the Market Supervision Department of China Securities Regulatory Commission, came to Shenzhen to investigate the "March 30 incident".

In a hotel room, Director Zhang met with me.

Zhang Ziping said: "Your report has been approved by President Liu Hongru: Strictly investigate and deal with it. I’m here to deal with this. Ning Zhixiang is my classmate in graduate department, the People’s Bank of China, Wudaokou, and I can’t cut it with my knife raised. When you come to Shenzhen, you must investigate, but you know, this investigation is like a ship leaving the dock. The destination of the ship is very clear: cross the river and dock;But when the boat reaches the middle of the river, it’s not up to you or me to sail.Do you understand what I mean? "

I nodded.

"How to investigate, first look at your attitude of Wang Shi."

"Be kind to others."

……

More than 20 years later, Vanke was involved in the equity dispute again. This time, the rival Baoneng Department was obviously more difficult than Junan Securities. In that year, Vanke defeated its opponent in just a few days, but this time, it took more than 200 days for both parties.

And combing Vanke’s moves so far is similar to that of that year.

First, the suspension-preemptive

Vanke set a precedent of suspension in 1994, and this time, this move was also used to resist the strong acquisition of Baoneng.

On December 18, 2015, Vanke A issued a temporary suspension notice, saying that it was planning to issue shares for major asset restructuring and acquisition of assets. At that time, Baoneng had continuously increased its holdings of Vanke through the secondary market, holding a total of 22.45% of the latter. Vanke’s suspension lasted for six months, and the restructuring target was always confusing. It was not until four months after the suspension that the reorganization target Shenzhen Metro was announced for the first time.

In the eyes of many people in the industry, Vanke’s emergency suspension is more to stop the crazy shareholding of Baoneng Department, fearing that the continuous increase of the latter will affect Vanke’s management and the latter’s right to speak. It is not excluded that Vanke chose to suspend trading first, and then find a reorganization object to win time for itself to fight back.

In the dispute between Jun and Wan, Vanke set a precedent for the suspension of A shares. After more than 20 years, this move has won Vanke six months of preparation time.

Second, restructuring-looking for a backer

In 2000, Wang Shi took the initiative to introduce China Resources Group, a central enterprise, after Vanke went through the dispute between Jun ‘an and An ‘an, hoping to adjust its shareholding structure, attract powerful consortia and become a strategic major shareholder. In the following more than 10 years, Wang Shi and Yu Liang publicly stated for many times that China Resources is the best major shareholder of Vanke, and the latter provided Vanke with lawyers and accounting professionals, which played a vital role in the organizational construction of Vanke and the entire management structure of Vanke.

When Vanke met Baoneng’s shareholding in 2015, it once turned to the major shareholder, but China Resources did not intervene.

Therefore, Vanke turned to Shenzhen Metro, another state-owned enterprise, to solve its own crisis.

According to the announcement of the trading plan issued by Vanke, Vanke intends to purchase 100% equity of Qianhai International held by Shenzhen Metro by issuing shares, with an initial transaction price of 45.613 billion yuan. Vanke will pay all the transaction consideration by issuing shares.

Out of this move, Vanke’s plan is to dilute the shares of Baoneng Department by issuing shares. But to Vanke’s surprise, this move also diluted the shares of China Resources, which directly led to the fierce opposition of China Resources. At the board meeting on June 17th, three directors of China Resources Department directly voted against the reorganization plan, showing a clear attitude.

Since the reorganization plan needs to hold the second board meeting and shareholders’ meeting, Baoneng Department and China Resources now hold 40% of the shares, and they can veto any proposal put forward by Vanke.

In the face of China Resources’ face, Wang Shi admitted frankly in Weibo that the last fig leaf had been removed.

The war between Vanke and Baoneng suddenly entered China Resources, making the prospect of this management dispute more complicated and unpredictable.

After the dispute between Jun and Wan, Vanke introduced China Resources, once the best major shareholder, but this move is obviously not omnipotent.

Third, public opinion-employees and shareholders go into battle together

In July, Baoneng Department demanded the removal of Vanke’s existing management, which directly aroused Vanke’s strong opposition.

Vanke Trade Union Committee sued Baoneng for harming shareholders’ interests, and the People’s Court of Luohu District of Shenzhen has accepted the case. According to the "Civil Complaint", there are five main claims of Vanke Trade Union, including the request to order five defendants to continue to increase their holdings of Vanke A shares when they hold 5% of Vanke A shares and thereafter, which is an invalid civil act; There are three main reasons for Vanke’s trade union’s lawsuit: Ju Shenghua, Qianhai Life Insurance, etc. involved in failing to fulfill their obligation to report in writing to the securities regulatory authority in the State Council, failing to fulfill their obligation of information disclosure in strict accordance with the requirements of the Securities Law and the Measures for Acquisition, and holding more shares is an invalid civil act.

In addition, more and more third parties have joined the camp.

Vanke’s largest natural person shareholder reported the real names of China Resources and Baoneng to seven regulatory authorities, including China Securities Regulatory Commission, China Banking Regulatory Commission and China Insurance Regulatory Commission, and questioned the relationship between them. Including questioning how many significant interests there are between China Resources and Baoneng Department; When did China Resources and Baoneng start negotiations and transactions on the status of Vanke’s largest shareholder? The reasons why the two sides jointly opposed the reorganization of Shenzhen Railway; Whether the secret agreement reached by the two parties on the change of ownership of the largest shareholder has been suspected of insider information trading and market manipulation, and whether the source of funds used by Baoneng for acquisition is legal or not.

In addition, Dong Huasheng, the independent director of Vanke, also disclosed the relationship between one of China Resources and Baoneng acting in concert in Weibo.

Compared with the last time, Vanke’s allied lineup is obviously stronger.

Fourth, uncover the bottom treasure-looking for Achilles’ heel?

On July 19th, Vanke issued a Report on Investigating and Punishing the Violations of Laws and Regulations of Ju Shenghua and Related Asset Management Plans under its control. In this report, Vanke revealed the number of shares held by Baoneng Department, the cost of holding shares, and even the details of the amount of nine asset management plans.

These nine asset management plans, that is, the sources of funds announced by Baoneng for the acquisition of Vanke A after the placard with a shareholding of 25%, said that these nine asset management plans are concerted actions.

According to the report, the interest rate range of the nine asset management plans is 6.5%-7.2%, and the average price of Vanke A shares purchased by Baoneng is 18.89 yuan/share. Based on the average interest rate and the existing period of 8 months, the average share price after considering the financing cost is about 19.83 yuan/share. This is the first time that Vanke is prepared to disclose the cost of Baoneng’s position.

Some analysts said that since the resumption of trading on July 4, Vanke’s share price has fallen by 30%. Vanke announced the cost of Baoneng’s position at this time, which undoubtedly kept the share price under pressure.

In addition, it is reported that due to the continuous decline in stock prices, some asset management plans plan to cancel the concerted action.

If the news is true, this is exactly the same as Vanke’s tactic of disintegrating the alliance more than 20 years ago.

While Vanke unveiled Baoneng’s card, Vanke listed a series of problems such as unclear disclosure of Baoneng’s asset management plan, illegal asset management plan, illegal transfer of voting rights and infringement on the interests of minority shareholders.

Some market participants believe that the timing of Vanke’s report is accurate. After Vanke A’s share price plummeted for a few days, this report accelerated the market’s concern about Vanke’s share price, because if the share price continues to fall, Baoneng’s nine asset management plans will have the risk of liquidation, which will undoubtedly accelerate the stock price decline, thus putting pressure on the regulatory authorities.

In the dispute between Jun and Wan, Vanke once directly cracked the crisis by learning that Ning Zhixiang colluded with Jun ‘an’s top management and obtained the evidence of "rat warehouse" in one fell swoop.

This time, Vanke clung to nine asset management plans, and the channel business was in a vague area of supervision. All the problems of how to judge were transferred to the regulatory authorities. Vanke chose to disclose it to the regulatory authorities when the stock price plummeted, with deep intentions, the above-mentioned market participants added.

The battle for Wanbao is still going on, but this time the Baoneng Department is not as vulnerable as Jun ‘an more than 20 years ago. At the same time, the whole regulatory environment is also changing. Vanke’s tactics have more progress and the brand of the times while maintaining its excellent tradition.

Can Wang Shi win this battle?

Revealing the Olympic etiquette, Miss Devil Training, this is the campus flower garden.


Miss Etiquette who appeared in the Good Luck Beijing Test Competition

Miss Olympic etiquette with outstanding charm (data picture)

Hard training (source: competitive newspaper)

  Youth Daily News Get off the Badaling Expressway at Xiaotangshan exit, head east for 3.5 kilometers, and finally find Songlanbao in sha he, Changping District, Beijing. The taxi stopped at the silver-gray gate of Changping Vocational School in Beijing. It happened that the bell rang after class, and dozens of attractive beautiful students filed out. The volunteers of Beijing Olympic Games ceremony-commonly known as "Miss Olympic Etiquette"-were trained here. What kind of hardships are behind the beauty and elegance?

  This is the campus flower garden.

  Since June this year, 1,250 girls from Beijing have come to Changping Vocational School to participate in intensive Olympic etiquette training. Their official name is "Beijing Olympic Games ceremony volunteers", and the popular saying is "Miss Etiquette".

  After 18-day intensive training, these miss etiquette candidates have been participating in the ceremony service of the 2007 "Good Luck Beijing" Olympic Games series since August. After the examination, 380 etiquette volunteers will be selected in mid-December to participate in the ceremony of awarding the Beijing Olympic Games.

  On December 5th and 6th, the reporter visited Changping Vocational School twice to visit this "beauty concentration camp" far away in the suburbs of Beijing. Teacher Fu from the school office told the reporter that there are many beautiful women in Changping Vocational School, but this time there are more beautiful women who come to participate in the Olympic etiquette training, which are basically the beauty of various schools. Therefore, it has almost become the big garden of Beijing campus flower!

  Devil training at 5: 00 a.m.

  The reporter got a "volunteer training schedule", and the training intensity arrangement above simply exceeded the college entrance examination students!

  At 5 o’clock every morning, the girls get up and tidy up the house; It is morning exercise time from 6: 00 to 7: 10, and the girls practice gymnastics, dance and basic skills with the tutor; After a simple breakfast, class begins at 8: 00, and an hour of basic ballet hand exercises and body training begins; At 9: 30, the etiquette class starts for two and a half hours, practicing etiquette actions such as standing, walking, walking and turning.

  Take a simple rest at noon, and start practicing classical dance and folk dance at 14: 00 pm to train the coordination and flexibility of the body, with a total time of about 90 minutes; At 15 o’clock, a two-hour etiquette class begins, the content of which is to consolidate what was learned in the morning. Don’t think that you can rest after class. There will be a 90-minute evening class starting at 19: 00, and the content will be a lecture on Olympic knowledge and etiquette.

  Busy every day until 22 o’clock at night, these candidate hostesses can return to the dormitory to rest. Teacher Yuan Chunyan, who is in charge of the training of volunteers in awarding ceremonies, said: "When it’s time to rest, the girls don’t even have the strength to go to the bathroom to freshen up, so they can fall asleep when they fall on the bed. For them, these efforts and efforts are aimed at being selected into the final’ Miss Etiquette National Team’ and being perfect when serving the Olympic Games. "

  Practice smiling by biting chopsticks.

  The hostesses who participated in the training came from various schools in Beijing, and most of their majors were related to the service industry. They had long been comfortable in reception work. Just because of the particularity of the Olympic Games, we have to strive for perfection and grasp every detail.

  Teacher Yuan Chunyan told the reporter: "The training of ceremony volunteers is basically the same as that of flight attendants, but it is more strict." Teachers should dig every detail. "For example, when awarding prizes, several volunteers turn around at the same time, and their steps should be consistent. For example, when bowing flowers, the forward direction is about the hip joint and the downward direction is 15 to 30 degrees. Because there are many people in a group when presenting flowers, there are often cases of inconsistent time and irregular movements when squatting, so it is required to have a consistent beat in mind. "

  The simple steps of holding a medal tray are also very particular. Teacher Yuan Chunyan said: "The arm holding the tray is about one punch away from the side waist. When holding the tray, the thumb must be exposed outside the tray. The most difficult thing is to control the pace and connect the awards. After walking a certain distance during the award presentation, the spacing between them should be the same, about thirty or forty centimeters. "

  Hao Jingyu, a etiquette volunteer, said: "What impressed me the most was practicing standing, walking, walking, turning around and smiling in etiquette training. In order to make our posture more upright, pace more in place, turn more neatly and smile more naturally when awarding prizes, we have to practice each movement hundreds of times. For example, standing posture is not as simple as we thought. Every etiquette volunteer must wear 5 cm high heels, a book on his head, and an ordinary piece of white paper between his legs and knees. One stop is an hour, and neither books nor papers can fall off, or they will have to be redone. When I rest, my legs are particularly painful to bend. "

  "Another example is practicing smiling. The smile of volunteers is the best business card in Beijing, so it is very important. " Hao jingyu said, "the laughter needed at the award ceremony is very different from our usual laughter. It is not acceptable to open your mouth wide or small, and even the number of exposed teeth is strictly regulated at 6 to 8. The teacher asked each of us to bite a chopstick in our mouth to feel when practicing smiling. It takes dozens of minutes to laugh like this, and even the facial muscles are numb. "

  After practicing for a long time, the girls’ teeth are sore by chopsticks, and the corners of their mouths are often abraded. Parents can’t help crying when they see the wound, and the girls smile and comfort their parents with a "nothing". Hao Jingyu said, "It’s the same when practicing walking, walking speed, turning around and other decomposition exercises. Everyone’s feet are ground with blisters, large and small, and after the blisters are worn out, they are ground with new blisters. So on and on, our movements are finally uniform."

  Daily food allowance for 25 yuan

  Girls don’t get much material gains by participating in Olympic etiquette activities. The only subsidy for three meals a day for the volunteers participating in the training is 25 yuan, which is almost the same as the dietary standard of ordinary people.

  Girls have more than a dozen kinds of food for breakfast every day, such as steamed buns, eggs, soybean milk, porridge and Chinese buns. Chinese food and dinner are staple foods such as rice, steamed buns and steamed buns, plus reasonable collocation of vegetables, meat and fish. Teacher Yuan Chunyan said that this recipe should not only ensure that the ceremony volunteers absorb enough nutrition, but also prevent them from getting fat due to overnutrition and affecting their body image. During the early training, there were many mosquitoes in hot weather. The school specially installed air conditioning for the student dormitory of the ceremony volunteers, and prepared mosquito-repellent incense tablets and pesticides to prevent scars from mosquito bites.

  Teacher Cui Weimin, deputy director of aviation service major in Changping Vocational School, told the reporter that the formal training will continue until March 2008. After intense training, it is the wish of volunteers to see their idols with their own eyes. Hao Jingyu said: "My idol is Liu Xiang. When I imagine that I may have the opportunity to serve Liu Xiang, I even have tears in my eyes, and I silently pray’ 2008, come soon’!"

  Never flinch from suffering.

  Despite strict training, accidents will inevitably occur in the actual operation process. When participating in the "Good Luck Beijing" archery team competition, a ceremonial volunteer accidentally stepped on the drainage pipe and twisted it. In order not to affect the progress of the award ceremony, she still kept an elegant smile, guided the award officials to walk the whole field, and walked back to the locker room only to find that the heel almost fell off completely.

  More than 30 students from Changping Vocational School have participated in the etiquette service of the "Good Luck Beijing" series of events. In order to prepare for the "Good Luck Beijing" triathlon, the etiquette team of Changping Vocational School was pulled to the competition site for training. In those days, the temperature in Beijing just plummeted and the cold rain continued, and the players wearing short-sleeved dresses had to keep training in the cold wind and cold rain. It’s really cold, so everyone happily hugs together to keep warm during the interval of training. Despite the suffering, none of the girls flinched in order to have a good performance at the award ceremony.

  Liu Changwen, a volunteer who awarded the prize for the "Good Luck Beijing" hockey competition, told the reporter: "My tray contains 18 gold medals and a trophy for the hockey competition, which is estimated to weigh at least 10 kilograms. At first, my hands were shaking. I was particularly afraid that shaking my hands too much would make the medal fall, but I finally persisted! " After the awarding ceremony, a member of the champion Australian team went to the rest area of Miss Etiquette and gave her champion flowers to Liu Changwen. "I was very excited at the time and felt that this was the best evaluation for our entire etiquette team!"

  How is Miss Olympic Etiquette selected?

  China has a population of 1.3 billion, so it is not difficult to select thousands of beautiful women. However, Miss Olympic Etiquette is called one of the "facades" of an Olympic Games, and it is not sloppy at all. Not all beautiful women meet the standards of Miss Olympic Etiquette.

  According to Zhao Dongming, director of the Cultural Activities Department of BOCOG, the standard of a hostess for the Beijing Olympic Games is "1.68m to 1.78m in height and 18 to 25 years old". Zhao Dongming said that miss etiquette must first be an Olympic volunteer; Secondly, the figure is better, and there is no strict regulation on the weight, but there are certain guiding standards for the measurements, because it involves the production of award-winning dresses.

  There will be nearly 100,000 volunteers for the Beijing Olympic Games, but among these 100,000 volunteers, it is difficult for other volunteers to experience what Miss Etiquette has experienced. Since the beginning of June, BOCOG has been selecting etiquette volunteers in many schools in Beijing. On the basis of various hard indicators, each school chose the best among the best, and conducted an all-round personal quality evaluation for each candidate. The selected candidate not only has outstanding appearance, but also has excellent academic performance and certain English conversation ability. The organizers also have strict requirements on the temperament, posture, skin and comprehensive quality of the candidates.

  During the selection in China Civil Aviation Management Cadre College, the school held a etiquette selection contest, especially in the whole school. More than 400 girls competed for 10 places, and the competition was fierce.

  The Korean Ministry of Justice said that Lee Myung-bak will be examined according to the opinions of the hospital during his hospitalization. According to the report, Lee Myung-bak was treated for diabetes and other diseases, and he was treated outside prison for three times last year. According to reports, Lee Myung-bak was sentenced to 17 years in prison for corruption and bribery, fined 13 billion won (about 69.24 million yuan), and pursued 5.78 billion won in criminal proceeds.

  It is worth mentioning that another former South Korean President, park geun-hye, was released from prison by amnesty at the end of December, 2021. Her lawyer, Liu Rongxia, said on the 16th that park geun-hye was in better health and would speak to the people when she left the hospital. Liu Rongxia also relayed that park geun-hye was sad that another former president, Lee Myung-bak, was not granted amnesty.

Interview | Chinese and foreign research is on the cover of nature: this protein allows robins to navigate geomagnetic.

Human eyes can see all kinds of colors in the visible light band, and ears can hear sounds in the frequency range of 20-20000 Hz, but we still don’t know whether we have the sense of sensing the earth’s magnetic field, which is a complete mystery.

The public calls it "the sixth sense", but scientists don’t like this statement. In the past few decades, they have been trying to pry open the tip of the iceberg of the mystery and find a breakthrough in birds. How do they realize the induction of geomagnetic field and use it? European Robin is an excellent research object. This nocturnal migratory bird has been proved to have the ability of geomagnetic navigation before, and they can use the geomagnetic field as weak as 0.5 gauss for long-distance orientation to complete the seasonal migration year after year.

But what is the mechanism behind it? For this question, it needs a highly interdisciplinary cooperation to answer one or two. At 23: 00 on June 23rd, Beijing time, the top academic journal Nature published a heavy research titled "Magnetic sensitivity of cryptochrome 4 from a migratory songbird" on the cover form, which was jointly completed by scientists from Germany’s Oldenburg University, England’s Oxford University, China Academy of Sciences’ Hefei Institute of Material Science, Purdue University, University of Texas Southwest Medical Center and Germany’s Freiburg University. Studies have proved that cryptochrome protein (Cry4) in birds’ retina is very sensitive to magnetic field, and it may be the long-sought magnetic sensor.

There are 6 corresponding authors in this study, one of whom is Xie Can, a researcher from the High Magnetic Field Science Center of Hefei Institute of Material Science, China Academy of Sciences, and the High Magnetic Field Science Center is the common communication unit. Together with the team of the University of Oldenburg, Xie Can’s laboratory successfully prepared and obtained the Cry protein of European robin, a nocturnal migratory bird, for the first time in the laboratory, which laid the foundation for the success of the whole study.

In an interview with The Paper (www.thepaper.cn), Xie Can said that this multi-party cooperation, which started in 2016, is only the first stage of research on biomagnetic induction in various laboratories. "This article is also the first stage of our long-term cooperation." There is still a lot of work to be explored by its laboratories and partners in the future.

Xie Can graduated from the Institute of Genetics and Developmental Biology, Chinese Academy of Sciences in 2001 with a doctorate in science. In August of the same year, he went to the United States to study molecular biophysics and structural biology in Timothy Springer laboratory of Harvard Medical School. From 2009 to 2019, he was a professor at Peking University College of Life Sciences. In November 2019, he was invited to join and transferred to the High Magnetic Field Science Center of China Academy of Sciences as a researcher. In December, 2020, we jointly established the International Magnetic Biology Frontier Research Center (IMF RC).

It is worth mentioning that in 2016, Xie Can Laboratory published its original breakthrough in the field of animal magnetic induction and biological navigation in the international academic journal Nature Materials, and discovered the magnetic receptor gene for animals’ perception of magnetic field for the first time in the world. The magnetic induction protein (MagR) encoded by this gene has intrinsic magnetism and can form a complex with Cry protein, so as to recognize the external magnetic field and respond. Based on this, Xie can put forward the hypothesis of "biological compass" for animals to feel magnetism. This work was rated as "Top Ten Progress in Life Sciences in China in 2015".

Professor Peter Hore from the Laboratory of Physical and Theoretical Chemistry of the Department of Chemistry of Oxford University is also the corresponding author of this latest study. Hore is one of the main schools of biological magnetic induction hypothesis, that is, the main contributor to the chemical radical-pair model that relies on cryptochrome. In an email to The Paper (www.thepaper.cn), he wrote, "If we can prove that Cry4 is a magnetic receptor molecule, we will also prove a fundamental quantum mechanism, which enables animals to perceive extremely weak environmental stimuli, and the intensity of this stimulus is one million times weaker than previously thought".

Referring to the above hypothesis of chemical free radicals, the time should be set back to 1978. At that time, German chemist Klaus Schulten and others proposed a preliminary model to introduce quantum entanglement into this research field, arguing that the magnetic induction mechanism of birds involves the entangled state of free radical pairs. Schulten’s team finally published the research results in 2000, pointing out that cryptochrome is probably the key molecule in the process of bird magnetic navigation, and boldly speculated on the magnetic induction process.

After nearly 20 years’ development, the outline of this hypothesis has become increasingly clear: firstly, the photosensitive pigment auxiliary group FAD in cryptochrome absorbs the energy of a blue photon, which causes the electronic transition of FAD group, leaving an empty orbit; Then the electrons are taken from the four adjacent tryptophan in turn, which is "electron transfer". At this time, the separated electrons have both spin singlet and triplet states due to quantum entanglement. Finally, the delicate balance between the two states can be determined by the direction of geomagnetic field, and this information can be transmitted to the brain in some way, so that organisms can respond to geomagnetic information.

The research team systematically and completely summarized the basic principles and supporting evidence of the free radical pair hypothesis from physics, chemistry and biology.

Compared with the previous theoretical research, this multi-party cooperative research takes the cryptochrome 4 protein of European robin as the main research object, carries out a series of high-precision spectroscopic tests, and carries out computational biology simulation, thus realizing the mutual verification of theory and experiment. This is the first comprehensive explanation of the photochemical magnetic sensitivity of free radicals in cryptochrome protein of nocturnal migratory birds, which confirms and perfects the magnetic induction mechanism of free radicals and provides an important basis for further explaining the geomagnetic orientation behavior of migratory birds.

Functional Cry4 protein from migratory birds

As early as 2000, scientists proposed that the photosensitive protein cryptochrome (Cry) was a possible magnetic induction protein through theoretical calculation. Theoretically, under the blue light condition, the information of external magnetic field can be transformed into the change of quantum yield caused by photoinduced free radicals in cryptochrome protein, which can be perceived by cells.

Why is cryptochrome protein considered by scientists as an animal magnetic induction molecule? The first author of this paper, Xu Jingjing from the University of Oldenburg, explained to the reporter of The Paper (www.thepaper.cn) that cryptochrome protein can bind to flavin adenine dinucleotide (FAD), also known as active vitamin B2. When FAD is excited by blue light, it will undergo a reduction reaction, which can seize the electrons of tryptophan (Trp) nearby in turn, thus forming a magnetically sensitive free radical pair [FAD-TrpH+].

"It can be said that FAD is the’ heart’ of this magnetic sensitive molecule, and only cryptochrome protein combined with the cofactor FAD has the prerequisite of magnetic sensitivity." Xu Jingjing is now a doctoral student in Henrik Mouritsen’s laboratory of the University of Oldenburg. Before studying in Germany, Xu Jingjing completed his master’s degree in the Institute of Electrician, Chinese Academy of Sciences, and received biochemical training in Professor Xie Can’s laboratory. .

It is worth mentioning that one of the reasons why the hypothesis of free radical magnetic induction has not been proved by experiments in birds since it was put forward in 1978 is that the recombinant expression of avian cryptochrome protein often loses its own function because of protein’s misfolding, which means the loss of the key auxiliary group FAD for cryptochrome.

"The biggest regret of free radicals to the hypothesis is that scientists have never been able to obtain experimental evidence of the magnetic sensitivity of cryptochrome protein in migratory birds. In the early attempts, some experiments were done in the laboratory with cryptochrome protein of plants or non-migratory animals, but as the most typical migratory animals, migratory birds have never been really studied because of the difficulty in purifying cryptochrome protein of birds. " Xie can added.

In this study, scientists finally obtained the functional cryptochrome protein of migratory birds that combined with FAD. Under the guidance of Xie Can and Mouritsen, Xu Jingjing expressed and purified Cry4 protein of nocturnal migratory birds with biological activity by using the Cold-Shock protein expression system customized and optimized in the laboratory. The protein sample showed a beautiful and transparent yellow-green color due to the presence of FAD chromophore, and mass spectrometry analysis showed that the FAD binding rate of the protein was as high as 97%. It laid the foundation for the success of the whole study.

The acquisition of Cry4 protein of European robin is actually quite tortuous. Xie Can told the The Paper reporter that as early as the beginning of the cooperation, that is, in April 2016, the original plan was that Xie Can’s laboratory would prepare the protein in China, and then send it to the foreign cooperation team by air transportation for the next test.

In the previous research on MagR, Xie Can has successfully expressed and purified the MagR and Cry proteins of homing pigeons (birds that can homing directionally but not migrate seasonally) and their complexes.

But the international transportation scheme is not feasible. Xie Can clearly remembers that on June 9, 2016, his laboratory sent samples to Oxford University for the first time, but it was difficult. "Long-distance international transportation of protein samples requires that the protein be frozen first, and then thawed after reaching the destination laboratory. At that time, we found a problem. Whether it is Cry protein, MagR protein discovered by ourselves, or a complex of the two, all these proteins related to magnetic induction are very unstable and extremely sensitive to temperature. In the process of freezing and thawing, the activity of protein is greatly reduced or even disappeared. " For Cry4 protein in this study, after long-distance transportation and freezing and thawing, the key FAD auxiliary group was dissociated from Cry4 protein, and Cry4 protein also lost its activity.

Under the circumstances at that time, how to "preserve" Cry protein was an urgent problem to be solved. Just then, Xu Jingjing was applying for a visiting scholar in Mouritsen Laboratory. In November 2016, Mouritsen put forward a proposal to let Xu Jingjing go directly to Xie Can’s laboratory to learn a whole set of protein expression and purification techniques. Under the framework of cooperation, Xie can is very open-minded. "This is also a good thing for us, because the articles we publish ourselves also hope that others can repeat them." After more than two months of intensive "crash course", Xu Jingjing entered the Mouritsen laboratory.

"It took about seven or eight months for Xu Jingjing to set up the whole system from scratch in Mouritsen laboratory, and the expression and purification of Cry4 protein were perfectly repeated, and it also had good activity." After the key cornerstone work was completed, Hore and Mouritsen could not hide their excitement. They expressed their excitement in the email sent to Xie Can, that is, at that moment, the three parties formally established a long-term cooperation. "The three of us are completely different backgrounds. Hore is a physicist, so he mainly does physical chemistry. Mouritsen does animal behavior and neurobiology. I do protein research, so the three of us have their own strengths, which can complement each other." Xie Can described this tripartite cooperation in this way.

 In the following two years, Xu Jingjing usually finished protein preparation in the morning, then took a flight from Germany to Britain, arrived at Oxford University in the afternoon and went straight to the laboratory to test the properties of the protein, that is, the magnetic sensitivity of free radicals to photochemical reactions. Xie can once "experienced half a trip" when she visited Oxford University. "I can realize that she basically shuttled between laboratories in two countries for more than two years, and this is how the experiment was done." Xie can said.

For the first time, the hypothesis of free radical pair was verified by the experiment of cryptochrome protein of migratory birds

In the course of this research, in view of the complexity of the experimental content and the extremely complicated tests involved, more laboratories joined in. It is mentioned in the paper that in order to study the influence of magnetic field on the photochemistry of cryptochrome, the research team has developed and continuously improved a variety of spectral techniques.

The research team of Oxford University has developed a series of spectroscopic techniques specially used to study the photochemical magnetic field effect of cryptochrome, including transient absorption spectroscopy and Cavity ring-down spectroscopy. Broadband cavity-enhanced absorption spectroscopy and electron paramagnetic resonance. Hore described it this way, "These devices were developed by the joint efforts of generations of talented postdoctoral and graduate students in the laboratory for many years."

Xu Jingjing said, simply put, the researchers put the protein sample in a magnetic field and irradiated it with 450nm blue light to detect the light absorption changes of the protein transient free radical pair under different magnetic field conditions and different time resolutions.

The experimental results showed that the free radicals in cryptochrome protein changed the yield after the magnetic field was applied, that is, the magnetic field effect, and the magnetic field effect of cryptochrome protein of European robin was 10 to 20 times stronger than that of non-migratory birds (chickens and pigeons).

The research team also clarified the mechanism of this magnetic sensitivity, that is, the electron transfer reaction triggered by blue light absorption. Protein molecule is composed of a series of amino acids: Cry4 has 527 amino acids, of which 4 tryptophan is very important for magnetic sensitivity. Under the excitation of blue light, electrons jump between FAD and these four tryptophan, resulting in so-called magnetically induced free radical pairs. Peter Hore of Oxford University and Ilia Solov’yov, a physicist in oldenburg, have calculated quantum mechanics to support this view.

In order to verify this, researchers at the University of Oldenburg further prepared tryptophan mutant protein of cryptochrome, that is, four tryptophan (WA, WB, WC and WD) in the electron transfer chain were replaced by phenylalanine (F) in turn, which had no redox activity and could not provide electrons to FAD, thus cutting off the electron transfer chain.

In each mutant protein, the electron transfer chain is 3, 2 and 1 tryptophan in turn. The transient absorption spectrum test results show that the free radical pair life of mutant protein is shortened from microsecond to nanosecond and picosecond. Electron paramagnetic resonance (EPR) test showed that the free radicals of wild-type protein [FAD+TRPDH+] were 2.2nm apart, and after the fourth tryptophan was mutated, the free radical pair [FAD+TRPCH+] was 1.8nm apart.

The paper points out that the experimental results are consistent with the theoretical simulation. In wild-type cryptochrome protein, electrons are transferred among four tryptophan in turn, and these four steps make the electrons that are not equipped at the end be the farthest apart, thus forming a long-lived free radical pair, and the ultra-fine effect of the latter’s spin coherence is the point of magnetic field action.

Xu Jingjing mentioned that, surprisingly, when the fourth tryptophan at the farthest end was mutated, the magnetic field effect of protein was stronger than that of wild-type protein, and it was stronger than that of cryptochrome in Arabidopsis thaliana, which is also an electron transfer chain of tryptophan.

The researchers asked, why did nature evolve a fourth tryptophan for avian cryptochrome protein, if its function was only to reduce the sensitivity of magnetic field? Further research shows that the decay kinetics of wild-type protein (ErCry4) and mutant (ErCry4 WDF) are similar in milliseconds, and the magnetic field dichotomy (B1/2) is similar. This means that the origin of their magnetic sensitivity is the same, both of them come from the third tryptophan, and the fourth tryptophan may not participate in the animal magnetic induction process.

So what role does this fourth tryptophan-mediated electron transfer play? Based on the above experimental results, Ilia Solov’yov and Hore put forward the mechanism of free pair dynamic equilibrium through spin dynamic simulation, that is, electrons may jump back and forth between the third and fourth tryptophan, and the resulting two free radical pairs [FAD-TRPCH+] and [FAD+TRPDH+] are in rapid dynamic equilibrium and play different roles respectively.

The two roles are: the free radical pair formed by flavin-third tryptophan is mainly responsible for magnetic field perception, and the free radical pair formed by flavin-fourth tryptophan is mainly responsible for biochemical signal transmission in vivo. "This mechanism has not been found in cryptochrome proteins of any species before." Xie can said.

The research team predicts that there may be other proteins interacting with cryptochrome proteins in the body, such as MagR or other unidentified signal molecules reported by Xie Can, to realize cascade amplification of signals or directional arrangement of cryptochrome proteins, and further enhance the magnetic sensitivity and direction recognition in organisms. "Of course, these speculations need more experiments in the future to confirm."

They speculated that, perhaps, it was through this ingenious mechanism that nature wonderfully optimized the free radical photochemical reaction of cryptochrome protein and realized the dual functions of magnetic field sensing and signal transmission, thus enabling migratory birds to find their way in their journey across the hemisphere.

Xie Can concluded to the The Paper reporter that the main breakthroughs of this study are as follows: first, the hypothesis of free radical pair is verified experimentally with cryptochrome protein of migratory birds; Secondly, it is found that cryptochrome protein 4 of migratory birds is more sensitive to magnetic field than that of non-migratory birds; Thirdly, it is found for the first time that the four conserved tryptophan in the hypothesis have two different functions: magnetic induction and signal transmission.

Moving forward in controversy, in vivo verification is not easy.

It is worth noting that there are still many controversies in the field of animal magnetic induction research.

Xie Can said that on the whole, the magnetic induction hypothesis that has attracted much attention so far mainly includes electromagnetic induction model, magnetite particle model, chemical free radical pair model dependent on cryptochrome and biological compass model. These hypotheses are supported by certain experimental evidence, but there are also some limitations or deficiencies.

Xie Can called the study of animal magnetic induction a "very non-biological" study. By analogy with the conventional research ideas of sensory biology, scientists have first known for sure the existence of a certain sensory system and what kind of sensory organ it is, and on this basis, they have identified the receptor cells, neural pathways and brain regions related to the sensory system.

But the study of magnetic induction is quite different. In this field, biologists often find and ask questions, but physicists put forward imaginative hypotheses, and then chemists will also participate in a large number of verification experiments. Previously, the discovery of MagR and the hypothesis of biological compass in Xie Can’s laboratory generally followed this thinking paradigm.

Although this latest research has made many important breakthroughs, Hore stressed that this is not conclusive evidence that cryptochrome is a magnetic sensor. Because "this study is an in vitro experiment with purified protein, and the magnetic field used in the experiment is much higher than the geomagnetic field." Henrik Mouritsen said, "We need to prove the sensitivity of this protein to geomagnetic field in birds’ eyes, but the current technical bottleneck does not allow us to do this."

The research team speculated that cryptochrome protein may show higher sensitivity to magnetic field in vivo environment. For example, in retinal cells, protein may be arranged in a fixed orientation, thus enhancing their sensitivity to the direction of magnetic field. In addition, they may interact with other proteins, such as the previously reported magnetic receptor MagR, and even other unidentified protein, so as to achieve the effect of signal cascade amplification. Scientists are also looking for these unknown "mutual partners".

Regarding the future research plan of this project, Xu Jingjing pointed out that finding the interaction protein of cryptochrome and conducting in vivo experiments are two major challenges.

In fact, up to now, even though the evidence of free radicals is the most comprehensive, many hypotheses of animal magnetic induction mechanism need to be continuously developed, improved and screened. "There are many schools in the field of magnetic induction, and the publication of every research result needs to be widely questioned and challenged by reviewers in the review process, and these reviewers often come from different academic schools with different academic viewpoints, and they are often your competitors. Only by persuading your competitors will it be possible to finally publish it through review. " The review of this paper for nearly two years also highlights the twists and turns of the process.

Xie can prefers to call this kind of controversy in the scientific community academic debate. "The extensive academic controversy and debate itself shows that the problem you are studying is very important, which is obvious." Secondly, Xie Can believes that with the academic controversy and debate, it often brings about the rapid development of the whole field, "because more and more rigorous experiments will be designed to verify their respective views. Whether it is proof or falsification, we are getting closer and closer to the truth of science. "

Xie Can believes that the field of animal magnetic induction is full of controversy, "because no hypothesis or model has been recognized by everyone so far, and each school has its own supporters."

Strong cooperation like this one may bring about accelerated progress. "This is a highly interdisciplinary field. If you want to do some interesting topics in the field of animal magnetic induction and biological navigation, it is often impossible to rely on a laboratory to complete it." Xie can said.

Xu Jingjing also mentioned that "solving a scientific problem requires the joint efforts of many disciplines. In our team, experts in various disciplines have world-class technology, which is very important for our research." She said that in the process of project promotion, researchers kept communicating and understanding the knowledge of different disciplines to achieve common scientific goals.

Sticking the neck, stabbing the knife, throwing the face … What has the United States done to this "important partner"

  "Never trust America. In the future, it will try to crush India … …”

  △ Screenshot of social media of Indian netizens

  On the recent social media platform, it is almost normal for the Indian people to comment on India-US relations like the above.

  After taking office in January this year, what has the new American administration done to make this "important partner" so untenable?

  This starts with the "stuck neck" of the United States in vaccine raw materials … …

  "Stuck" on the issue of vaccines

  According to data from the Indian Ministry of Health, the country’s newly confirmed cases of COVID-19 in the 24 hours as of 8: 00 am on the 26 th have set a new national record for five consecutive days, and once again set a new record of new cases in a single country in the world; At the same time, the number of deaths on that day also reached a new high in India since the outbreak.

  △ 25th local time, where will you go, outside a hospital in the Indian capital.

  Previously, in response to the worsening epidemic situation in China, Adal Punavara, CEO of the Indian Serum Research Institute, used social media to "implore" US President Biden to lift the ban on India’s export of vaccine raw materials in order to increase India’s vaccine production.

  △ Punavara social media screenshot

  It turns out that in order to ensure that vaccine manufacturers such as Pfizer in the United States can get enough raw materials to achieve all-weather production, Biden invoked the National Defense Production Act at the beginning of his tenure to prohibit the United States from exporting key raw materials for vaccine production. Even when the vaccination rate and reserves of the United States have been ahead of the world, the Biden administration has been slow to "let go".

  For the United States, the Indian media simply dismissed it as "vaccine mafia behavior."

  △ India zeenews News Network report screenshot

  The indifference of the United States has angered the Indian people. According to Indian media reports, the anti-American and anti-Western sentiment of Indian netizens on social media platforms has continued to rise recently.

  Some people accuse the United States of ingratitude: "Remember hydroxychloroquine? When Trump raised the demand last year, India immediately lent a helping hand, although the Indian people were not enough. 1.3 billion Indians will remember who stood by when they needed help. "

  △ Screenshot of social media of Indian netizens

  Perhaps facing too much pressure, the White House finally said on the 25th that it would provide India with much-needed medical resources. But at this time, India’s vaccine raw materials have been cut off for several months, and the domestic epidemic has deteriorated to an unprecedented level. At present, the Indian side has not responded to this. I wonder to what extent this gesture of "sending an umbrella after snow" by the United States can calm India’s anger.

  "Stabbing a knife" in regional security

  Not long ago, another thing the United States did also angered India.

  Earlier this month, the destroyer USS john paul jones, while crossing the Persian Gulf to the Straits of Malacca, forcibly entered the Laksha Islands in the exclusive economic zone of India for so-called "free navigation".

  What makes India even more dissatisfied is that the US Navy’s Seventh Fleet also issued a statement publicly declaring that this action has not been approved by India.

  △ US destroyer john paul jones

  In this regard, The Times of India wrote in the first sentence of its report: "There are rare differences between India and the United States on the rapidly developing defense relations between the two countries."

  △ "Times of India" report screenshot

  In view of the close defense relationship between India and the United States, this incident is obviously extraordinary. Afterwards, the Indian government expressed "concern", which triggered ridicule and dissatisfaction from Indian public opinion, and regarded it as a manifestation of "weakness" towards the United States.

  Many Indians believe that the United States "can’t believe that they will stab India in the back."

  "Throw a face" in economic and trade cooperation

  I am afraid that the more lasting pressure from the United States on India is still in the economic and trade field.

  As early as June 5, 2019, the Trump administration at that time terminated the GSP treatment for India for decades on the grounds that the US trade deficit with India was too large, which brought a new blow to India, where the economic growth rate slowed down significantly and the unemployment rate hit a new high.

  △ US President Trump (left) and Indian Prime Minister Modi (data map)

  On the 26th of last month, the Office of the US Trade Representative announced that the trade investigation on India and other six countries related to the digital service tax in Article 301 had entered the next stage, and the possibility of imposing punitive tariffs on these countries was not ruled out. Indian media said that the United States may impose retaliatory tariffs of up to 25% on Indian products.

  △ "India Tribune" report screenshot

  In addition, 11 economies, including India, are still on the US exchange rate policy monitoring list.

  … …

  The "new hatred and old hatred" of the piles has made Indians feel sad and angry.

  The Times of India once quoted the questions of netizens in the country: "Restrict the export of vaccine raw materials, label India as a currency manipulator, enter Indian waters without saying hello, and publish a negative report on human rights and minority rights in India … … This is what allies do? !”

  In this regard, Wang Shida, deputy director of the South Asia Institute of China Institute of Contemporary International Relations, pointed out that in recent years, the United States has stepped up its efforts to win over India to implement the so-called "Indo-Pacific strategy" and attempted to extend its power to the Indian Ocean region step by step, but in the process it has never regarded India as the only "partner" that the United States relies on in South Asia. In fact, the differences between India and the United States in many fields make it difficult for the two sides to become true allies.

  Wang Shida:"On the one hand, the United States wants to use India to promote its so-called ‘ Indo-Pacific strategy ’ ; But on the other hand, the starting point of American foreign policy is always to safeguard America’s own interests and global hegemony. How long can the cooperation between the United States and India last? There has been some reflection in India. Therefore, India has distanced itself from the United States to some extent, and at the same time it has also taken quite strong precautions against the United States. "

People’s Forum Online Comment | Strive to be loyal to the party, live up to the people, noble and pure.

     In his important speech at the opening ceremony of the training course for young and middle-aged cadres at the Central Party School (National School of Administration) in the spring semester of 2022, the Supreme Leader stressed that young cadres are the hope of the development of the cause of the party and the country, and they must build a solid foundation of ideals and beliefs, keep the defense line against corruption and change, establish and practice a correct view of political achievements, practice excellent skills, carry forward the spirit of responsibility and struggle, implement the party’s mass line, temper their political character of loyalty to the party, establish their feelings of being loyal to the people’s home country, and pursue noble and pure thoughts. The earnest words are full of deep affection and ardent expectations, which points out the direction for the healthy growth of young cadres. To this end, it is necessary to profoundly study and comprehend, strictly benchmark the table, work hard to implement it, and create achievements worthy of the party, the people and the times.

  Temper the political character of loyalty to the party."The greatest virtue in the world is loyalty." For party member cadres, the first political character is loyalty to the party. "Loyalty to the party and never betraying the party" is written in the pledge of joining the party, which is the most fundamental requirement for party member. Along the way, our party has experienced numerous dangers and hardships, but no difficulties have overwhelmed us, and no enemy has been able to defeat us, relying on the loyalty of Qian Qian and party member. Young cadres are a new force in the development of the cause of the party and the country when they are born in great times. Only when they are politically hard can they be strong in action. Therefore, it is even more important to be loyal to the party, practice hard work and do real work, and always believe in and love the party for the party. We should strengthen our ideals and beliefs, strengthen our theoretical arms, resolutely be loyal to the Party’s theory, resolutely take the Party’s banner as the banner, arm our minds with truth, strengthen the cultivation of party spirit, build a solid foundation of faith, supplement the calcium of the spirit, keep our mind on the rudder, and take the belief in Marxism and Socialism with Chinese characteristics as our lifelong pursuit; We should do the "two maintenance", observe the "four obedience", resolutely perform the duties of party member, resolutely undertake the obligations of party members, take a clear-cut stand on politics, believe in, rely on and obey the organization, and be more determined and effective in supporting the party’s program, observing the party’s articles of association, fulfilling the obligations of party members, implementing the party’s decisions, strictly observing the party’s discipline and keeping the secrets of the Conservative Party.

  Establish the feelings of home and country that live up to the people."Jiangshan is the people, and the people are Jiangshan." Taking the people as the center is the fundamental political position of our party; Living up to the people is a distinct lofty feeling of the Communist Party of China (CPC) people. The party unites and leads the people in revolution, construction and reform, the fundamental purpose of which is to make the people live a better life. No matter how much challenges and pressures they face, no matter how much sacrifices and costs they pay, this point will remain unshakable and unshakable. Since the beginning of politics, young cadres should firmly establish people’s feelings, take the benefit of the people as their greatest achievement, deeply understand and grasp the profound connotation of "the times are the writers, we are the respondents and the people are the reviewers", solve the problem of "why, what and what to keep" in politics from the perspective of political achievements, and insist on realizing, safeguarding and developing the fundamental interests of the overwhelming majority of the people as the starting point and the end result of all work, and persist in developing for the people. We should cultivate the spiritual realm that I will be selfless and live up to the people, maintain the attitude of "I don’t have to be successful", truly regard myself as a member of the masses, take the affairs of the masses as our own business, do everything with public interests at heart, regardless of personal gains and losses, and achieve "selfless world and wide heart", and win the good reputation of the people with tangible achievements.

  Pursue noble and pure ideological realm."Being honest and upright, being honest and upright." Honesty is the most innocent background of communist party people. If party member cadres’ morality declines, their personal morality is chaotic, and their morality falls and their behavior is out of order, they will naturally be plagued with problems and will only ruin themselves in the end. Especially for young cadres, it is even more important to tie the "first button" of honesty and politics, so that nobility and purity can run through and become character. We should be self-vigilant, cautious and independent, fully inherit and carry forward the fine style of hard work, cultivate our positive, healthy and clean life interest, be honest with Ming Dow and Wilder, dust off "ideological dust" diligently, think more about "greed" and often break the "thief in the heart", and ensure that there is no rash thinking inside and no rash action outside. The more unsupervised and unsupervised, the more we must hold the ruler. We should be awed and stop what we do, always refer to the party’s theory, line, principles and policies, party constitution’s party rules and regulations, and our initial mission, see clearly whether something should be done or not, always remain sober and firm, exert ourselves to restrain our words and deeds, be alert to minor matters, and always do not deviate from the line, cross the line, and do things cleanly.The Communist Party of China (CPC) people will always be honest and clean.
