The value-added tax invoice data with a wide penetration is a window to observe the production and operation of market players. According to the data released by State Taxation Administration of The People’s Republic of China on May 28th, in April this year, the sales revenue of national enterprises increased by 12.9% on average for two years, which continued a steady and positive trend.

On the whole, in April this year, the sales revenue of Chinese enterprises continued to grow steadily, the industrial economy continued to recover, consumption and investment steadily improved, and the recovery growth trend of the national economy continued to strengthen.

Zhao Lianwei, deputy director of the Revenue Planning and Accounting Department of State Taxation Administration of The People’s Republic of China, said: "The VAT invoice data shows that in April, the sales revenue of national enterprises increased by 24.6% year-on-year, 27.5% over the same period of 2019, and the average growth rate in two years was 12.9%, continuing the steady and good trend since the second half of last year."

In terms of industrial enterprises, the sales revenue of industrial enterprises increased by an average of 10.1% in two years, reflecting the steady recovery of the industrial economy. Zhao Lianwei said: "Among the 41 major industries, 38 industries have achieved positive growth on average in two years, and 16 industries have achieved an average growth rate of more than 10% in two years."

In the wholesale and retail industry, the sales revenue of the wholesale and retail industry increased by 12.3% on average in two years, one of which is the rapid growth of upgrading consumption. "VAT invoice data shows that in April, the national wholesale and retail sales revenue increased by 26.2% year-on-year, an increase of 26.1% over the same period in 2019, and an average increase of 12.3% in two years. Among them, the consumption of upgrades has grown rapidly, and the retail sales of watches, health care equipment, photographic equipment and nutrition and health products have increased by 21.6%, 46.7%, 9.4% and 25% respectively in two years.

According to the data of VAT invoices, from January to April this year, the sales revenue of the national construction industry increased by 39.6% year-on-year, by 31.1% compared with the same period in 2019, with an average increase of 14.5% in two years, reflecting the continued recovery of investment. The investment structure was gradually optimized, and investment in new infrastructure increased.

In addition, State Taxation Administration of The People’s Republic of China also released the relevant data of newly established tax-related market entities. "Newly established" means that they have gone through the relevant procedures for the registration of market entities, and "tax-related" means that certain production and business activities have taken place. The data shows that thanks to the continuous release of a series of policy dividends, such as tax reduction and fee reduction, "streamline administration, delegate power, strengthen regulation and improve services" reform, and optimization of business environment, in April, there were 1.336 million new tax-related market entities, an increase of 5.1% compared with March, an increase of 21% and 20.3% respectively compared with the same period in 2020 and 2019, with an average increase of 9.7% in two years.

In terms of types, the number of newly-established individual industrial and commercial households reached 621,000, which is about half of the total number of newly-established businesses. The executive meeting of the State Council made it clear that we should continue to provide targeted support to small and micro enterprises and individual industrial and commercial households, including implementing tax reduction and fee reduction measures and helping them cope with the impact of rising prices of raw materials.

　　Interpol Liu Zhigang has been looking for a rose.

　　As the most critical "blood color" in 12 murders, this "flower" has disappeared for 14 years.

　　In less than three months from 2005 to 2006, a six-member gang successively robbed and killed 12 taxi drivers in two provinces and three cities, including 11 men and 1 woman, and seized more than 4,000 yuan. This is "the largest serial homicide case against taxi drivers" since 1949.

　　The day after the last case happened, the series of cases were solved, three people in the gang were brought to justice, and two minors were sentenced to life imprisonment, but one person has not yet been brought to justice. The confession of the accomplice points to this man named Yang Tong, saying that he was the first mastermind who decided to rob and kill. Since then, looking for Yang Tong, the principal criminal who disappeared, has become a "must-test big question" for Heilongjiang police every year.

　　In the wanted order issued by the police, the 22-year-old young man has a handsome appearance, and his features include "a red rose tattooed on his right upper arm".

　　victim

　　He Qiaolian (a pseudonym) remembers that on February 26, 2006, her husband Liu Zhongchun (a pseudonym) was in a hurry to go out and pull a job just after lunch.

　　The red Xiali taxi he drives will be scrapped in seven days. The couple bought it with a loan from the bank. Although it is always bad, it is still the only source of income for the family.

　　Liu Zhongchun and his wife calculated that they would quit after running these days and do some business in the future. Seeing that his niece is getting married, he wants to run for money. If he has a lot of work, he can also run for a ticket and go back to his hometown in Jilin to see his parents.

　　Before going out that afternoon, the family-oriented man soaked two clothes in a basin and asked his wife to wait for him to come back and wash them.

　　The next day, 43-year-old Liu Zhongchun was found in a drainage ditch 28 kilometers away from anniversary, with 56 knives. He Qiaolian’s sister said that in order to let the knife penetrate the abdomen smoothly, the murderer opened Liu Zhongchun’s upper body cotton-padded clothes.

　　This is the seventh taxi driver murder case in Zhaoyuan County, Daqing City, Harbin City and Zhaozhou County of Heilongjiang Province since December 2005. The public security organs found that these cases were committed by the same group by analyzing the means of committing crimes, comparing the knife edges and inspecting the traces on the scene.

　　The murdered drivers were all in dozens of knives. After a driver was killed, the only 24 yuan money on his body was taken away; Two drivers were killed and thrown into the same grave; A driver tried to escape, but the murderer threw him down and killed him … … Liu Zhongchun was the victim who was stabbed the most.

　　Before killing Liu Zhongchun, a group of murderers clashed. After participating in two robberies, 17-year-old member Jiang Ming (pseudonym) stole two stolen mobile phones and more than 200 yuan while other members were in the bath center, and then fled.

　　Subsequently, other people had no money to pay for the bath, so they "mortgaged" one person, and the other three people went out to rob and kill a red Xiali taxi driver, that is, Liu Zhongchun.

　　Two days later, Jiang Ming enabled the stolen mobile phone, and Daqing Public Security locked the signal to capture it.

　　Liu Zhigang, Yu Tao, Sun Yanhui and other police officers in different positions at that time all remember that in those days, the weather in Daqing was very cold, and almost all the public security organs in the city took to the streets to participate in the arrest, and police cars flashed warning lights throughout the city.

　　Three days later, the remaining four people in the killing gang were arrested. Three of the five people were sentenced to death and two were sentenced to life imprisonment.

　　Fourteen years later, He Qiaolian told reporters that she forgave two underage adults, but the nightmare did not completely let her go.

　　She often dreams that her husband comes back to wash those two clothes. She cries and asks "Where are you" and "Why don’t you go home", but the husband in her dream always doesn’t look at her.

　　In the home where Liu Zhongchun will never go back, there is no trace of his life. He Qiaolian moved away from the former site and raised her daughter alone. This 50-year-old woman has many empty bottles of eye drops at her bedside. Her eyes are not good, and the font in her mobile phone can only be seen when it is adjusted to extra large. She once heard a doctor say, "Tears are hot, and crying all the time burns the fundus."

　　The case materials and old newspapers of that year were sandwiched in the family photo album by her. She and her daughter seldom talk about Liu Zhongchun, let alone the sixth man who disappeared. She had seen Yang Tong’s name in the litigation materials. She hated this young man who had never met before, and even wanted to go to his hometown to find out, "Why would he want to kill someone?".

　　Chaser

　　Liu Zhigang kept Yang Tong’s photos and wanted orders in his computer and mobile phone, and also printed out a copy at hand, then took it out and stared at it regularly.

　　When Yang Tong absconded in 2006, Liu Zhigang was 33 years old. He was a criminal policeman of the Eighth Brigade of the Criminal Investigation Detachment of anniversary Public Security Bureau, mainly responsible for chasing fugitives.

　　The closest one was in March 2006, when Liu Zhigang learned that Yang Tong was in Harbin, but when he got there, he had already fled. The 14-year hunt has begun. In the words of Han Yanchun, a colleague from Liu Zhigang, in this world, apart from Yang Tong’s parents, "we are the people who miss him the most".

　　Over the years, the police have received many tips about Yang Tong. Some say that he smashed the stall selling eggs, some say that he bought explosives and guns to do something important, some say that he wants to sneak out of Yunnan, and some people post that Yang Tong inquired about the policy of "surrender leniency". All these clues are finally "checked out".

　　After 2010, Yang Tong’s ID card information was registered in many places, such as Didi, Alipay, Baidu Takeaway, ofo bike-sharing, YY voice account, Perfect World, Street Basketball, Jiuyin Zhenjing and other game accounts, and dozens of mobile phone numbers were also registered. The police speculated that the A-level wanted order of the Ministry of Public Security sometimes appeared on the boot screen of the computer in the Internet cafe, and the identity information was easily "borrowed" by others.

　　In 2012, Liu Zhigang took over as the captain of the pursuit brigade. His superior, Tianhua Wang, then the criminal investigation detachment leader of Daqing Public Security Bureau, told him, "If you don’t do anything for a year, you can just get Yang Tong back.".

　　In the past 14 years, the task force that pursued Yang Tong has changed five batches and the criminal police have changed three times. Liu Zhigang and his colleagues spend almost a third of their time chasing after each other all over the country every year. Knowing that Yang Tong may go home for the New Year, they will go to his hometown to lurk next door, or hide in the van to spy on him.

　　Liu Zhigang is 47 years old, with wrinkles and white hair. Criminal investigation detachment has been joined by criminal police after 80 s and 90 s. When newcomers report for duty, they will listen to the "old policeman" telling the story of the sixth man who disappeared and the serial murders of that year.

　　After 80s, Wang Shuai was transferred from other provinces and saw the world, but when he heard the tragic murder, he still said it was "unheard of". Later, he took the initiative to join the task force.

　　"Every quarterly, annual assessment or special action, the superior must mention Yang Tong." Luo Hongwei, deputy detachment leader of the Criminal Investigation Detachment of Daqing Public Security Bureau, said that sometimes "the face is red when asked", and "12 people died violently, the principal offender could not be found, and the family members were restless. For the criminal investigation police, this is a great shame."

　　The new office building of Zhaoyuan County Public Security Bureau is on the bank of Songhua River, and the glaciers in the sun are particularly bright. But for criminal police, what is more conspicuous is the left front of the gate and the place where the tenth victim was dumped. At the time of the crime, it was still a wasteland.

　　Yang Tong’s name and his white and delicate face have been flowing in the huge data system of public security organs, looking for relevant data.

　　Iterative technology is like a finer mesh screen, with smaller mesh and higher precision.

　　In 2016, after a nationwide systematic screening, the police determined that Yang Tong had not activated his identity information, inferring that he was using someone else’s identity or living under a false identity.

　　In August, 2020, Sanmenxia Public Security Bureau of Henan Province used the database to match a person who was imprisoned for theft, which was very similar to Yang Tong.

　　perpetrator

　　No one can tell why Yang Tong, who just turned 22 in the winter of 2005, suddenly took two young boys to rob him.

　　He was born in Erjingzi Town, Zhaozhou County. His parents are still alive. He has a younger sister at home. When he was 6 years old, his family moved to neighboring Zhaoyuan County to sell candy bars. He graduated from primary school, went out to work at the age of 18, sold seafood in Harbin and Shuangyashan, cut vegetables for restaurants and talked about love.

　　According to the confessions of accomplices Wang Dongcheng and Fan Mingkun, 20-year-old Wang Dongcheng is a neighbor of Yang Tong, who works in anniversary. One day at the end of November 2005, Yang Tong found Wang Dongcheng and said that he would take him to do a job of "making more money". Later, the two returned to Zhaoyuan County, and Yang Tongdao introduced Fan Mingkun, a 21-year-old elementary school classmate, to Wang Dongcheng.

　　The three initially planned to rob the grocery store. When they walked to the door and saw many people in the store, they gave up.

　　The reason for robbing a taxi is that there is no need to look for the target of the crime, and it is all over the street; There are ready-made vehicles to escape; More importantly, the taxi must have cash.

　　"Even if a person just went out and didn’t pull it, the driver must have change with him. The change can at least break a 100 yuan." Fan Mingkun confessed. The first selected driver "looks like an old man" and "speaks softly and has no energy".

　　For the first time, Yang Tong didn’t do it. A policeman who handled the case said that Yang Tong was a "ghost" (flexible in mind) and mainly assumed the role of strategist and finance. He is responsible for chatting with the driver, observing the surrounding environment and waiting for an opportunity to signal to stop. After committing the crime, he insisted on selling or destroying the victim’s mobile phone, and the money he grabbed was also distributed by him.

　　On December 14th, 2005, three people returned to Saertu District of Daqing City, which means "the place where the moon rises" in Mongolian. Here, they robbed a yellow Alto taxi. This time, "Yang Tong stabbed the driver in the back with a knife".

　　When killing the fourth driver, Yang Tong suddenly became "frightened".

　　On December 18th, 2005, near midnight, Yang Tong robbed a red Jetta taxi in Daqing, and Yang Tong and Wang Dongcheng dragged the tied driver to a grave. After a while, Yang Tong came back by himself and said, "I can’t do it" without saying why. Fan Mingkun didn’t ask, took the knife and walked to the grave. At this point, Wang Dongcheng has pushed the driver against the tree, and Fan Mingkun stabbed the driver in the chest. After the driver broke free, he ran two steps and cursed them for "not paying attention" and "killing people after taking the money". Fan Mingkun threw himself on the ground and stabbed him with a knife.

　　Yang Tong believes that "those two people are crazy". He told the police that he couldn’t control Wang and Fan Er people, and they also had differences on how to deal with their mobile phones.

　　Yang Tong left. More than two months later, Wang Dongcheng and Fan Mingkun found Fan Mingkun’s brother Fan Minghui and two 17-year-old teenagers Jiang Ming and Sun Xiao (a pseudonym) to join in.

　　The new gang is even crazier. From February 25th to 28th, 2006, they committed eight crimes in four days.

　　Local taxi drivers began to be alert, and there were not many men on the night shift. Fan Minghui’s left leg was amputated at a high position due to electric shock, and he relied on a crutch. From February 25, he stood alone on the street and took a taxi, and then picked up the other four people in the name of "picking up friends". When the car shop goes to a remote place, Fan Minghui will say, "My leg is numb and I need to change my position" and let the driver stop.

　　"My image, standing on the side of the road, there is no taxi." Fan Minghui said during the trial.

　　The driver of Hafei Lubao taxi was the only woman among the 12 victims. On the afternoon of February 25, she met these five men in Zhaozhou County by car and took the initiative to whistle and ask them if they wanted to take a taxi.

　　"I didn’t want to rob her, but this model has never been seen before. She took the initiative to recruit us and got on the bus." Afterwards, Wang Dongcheng confessed.

　　After Jiang Ming confessed that Yang Tong was the mastermind, Daqing police went to Erjingzi Town to arrest people. According to the police investigation afterwards, the head of the village where Yang Tong’s family is located said, "What happened to your Yang Tong? Why did the city bureau come?" When Yang Tong’s father heard that he immediately found his son and learned that he had "killed", he gave him 1000 yuan money to help him escape. Father Yang and the village head were both sentenced for harboring crimes.

　　Yang Tong boarded the train from Harbin to the south and got off at Zhoukou Station at random. After being arrested, he told the police that he had found an ID card and used it to work in a hotel in Taikang County, Zhoukou City. In 2008, Yang Tong was jailed for two years for theft in this capacity.

　　When he was released from prison, he was almost a different person. Since then, he has stopped taking trains, planes and buses, and he is afraid to register an Internet account. In a sense, he disappeared.

　　Search with Chinese search engine, you can see the discussion of the case by netizens. Some people listed Yang Tong as the "Top Ten Most Wanted", ranking third, and speculated why he wanted to tattoo a red rose on his body.

　　Impersonator

　　On October 29th, 2020, Liu Zhigang saw the flower again. It appeared on the arm of a man in Henan province, and its appearance was exactly the same as that obtained by the police 14 years ago.

　　At this point, Yang Tong, a Class A wanted criminal of the Ministry of Public Security, was finally arrested.

　　In September this year, the fifth task force to hunt down Yang Tong was set up. They have prepared winter clothes and will go to Henan to fight a protracted war.

　　In 2010, Yang Tong, who used another person’s identity, was released from prison. Sun Yanhui, now the head of the Criminal Investigation Brigade of Zhaoyuan County Public Security Bureau, investigated his cellmates that year, and narrowed the last place where Yang Tong appeared to Jicui Community in Luohe City, and the time was also locked in 2013.

　　Not long ago, standing on the street of Jicui community, 10 policemen felt like "10 ants": there were two wholesale markets with a large floating population. In 2010-2013, when Yang Tong appeared, there was also a woven bag factory with 30,000 employees, which had closed down and the workers were scattered everywhere. "Want to find a 7 years ago or even 10 years ago ‘ Dummy ’ " Luo Hongwei said that it was extremely difficult to check one by one, so he decided to start with the flower market first. After years of pursuit, they met "a little luck" — — An old couple saw Yang Tong’s photo and said, "Isn’t this the small northeast?"

　　It is said that "Little Northeast" has long stopped sending flowers, changed to rockery business, and opened its own store. Luo Hongwei and his party quickly found the store address provided by the old couple.

　　In order to avoid the exposure of the northeast accent, Han Yanchun entered the store to inquire about the situation with the cooperation of a local police station in Henan. Henan police talked with the woman at the front desk, while Han Yanchun walked to the back yard and found a man with long hair lying in a tent in the courtyard covered with a quilt.

　　After only one look, Han Yanchun decided that eyebrows and eyes could not be wrong, and this person was Yang Tong.

　　When he was held down, Yang Tong still denied his identity. He didn’t admit it until the policemen who came to support tore off his clothes and saw the red rose.

　　In the live video recorded by the law enforcement recorder, in order to ensure correctness, the police asked Yang Tong the names of his parents and sister, and he answered verbatim.

　　The missing sixth person has finally been found.

　　After the news of Yang Tong’s arrest was announced, Liu Zhigang, Luo Hongwei, Han Yanchun and others "went crazy in the circle of WeChat friends", and some people got hundreds of praises, "the most in history". Some retired policemen specially called to ask how they caught Yang Tong.

　　At the beginning of November this year, the police of the task force escorted Yang Tong back to their hometown.

　　When passing through Erjingzi Town, Yang Tong suddenly said, "Leader, why don’t you turn a corner and let me go home and see my parents? I haven’t seen them for so many years."

　　Returning to the scene of the first murder, Yang Tong, who shocked Heilongjiang and Jilin provinces in those years, is no longer the 22-year-old young man. He has long hair, fat body and blurred eyes — — When he saw a policeman with his hands in his pockets, he immediately squatted on the ground.

　　"What happened to Yang Tong?" Yu Tao, deputy director of Zhaoyuan County Public Security Bureau who led the team to identify the scene, asked.

　　"I thought you were going to shoot me." He straightened up when he saw that the police took out a mobile phone, not a police gun.

　　In 2006, Wang Dongcheng and others’ criminal incidental civil judgment, the victims were no longer "taxi drivers" in the news. Behind their names, the column of relatives’ names showed that two 61-year-old Harbin elderly people lost their sons; Two elderly people in Qinggang County who were over 70 years old also lost their sons; A 44-year-old man in Zhaozhou County lost his wife and his newly grown son lost his mother. Two elderly people in Helen who were over eighty lost their sons, and their 12-year-old grandson lost his father. Two 36-year-old and 37-year-old anniversary women, two 29-year-old Jilin women and a 35-year-old Helen woman all lost their husbands. An 11-year-old girl in anniversary lost her father.

　　After the first trial, Jiang Ming was sentenced to 20 years in prison. The victim’s family insisted on appealing, and did not hesitate to give up civil compensation, only seeking severe punishment. Finally, Jiang Ming was sentenced to life imprisonment. At the beginning of the lawsuit, the families of the victims called each other to express their condolences. Later, they stopped contacting each other because many families could not afford the telephone bill.

　　When he finally arrived at the case, Yang Tong had been married for 10 years and had a son and a daughter. The wife is 36 years old and knows nothing about her husband’s past. More than 2,000 kilometers away, He Qiaolian saw the news that Yang Tong was arrested, and tears came out. She was also 36 years old when her husband died with 56 knives.

　　She and Liu Zhongchun’s daughter are 18 years old, and have long forgotten her father’s appearance, and even can’t remember calling her father. When Yang Tong left Luohe, the policemen opened the window and let him see his family. His 2-year-old and 4-year-old children don’t understand what happened. They stand on the street and wave to their father in the window: "Bye, Dad."

　　CCTV News:According to the website of the Ministry of Education, in May 2022, the illustration of the eleventh set of primary school mathematics textbooks by People’s Education Publishing House (hereinafter referred to as People’s Education Press) was widely concerned by the society. The leading party group of the Ministry of Education attached great importance to it, and set up an investigation and disposal working group headed by the leading comrades of the leading party group and deputy heads by two members of the leading party group.

Second, it is not serious and standardized, and some illustrations even have errors. There are too many illustrations, some of which have low professional standards, and some illustrations have scientific and normative problems.

　　重点一：习主席去年曾给南开大学8名入伍大学生回过信

　　2017年的最后一天，国家主席最高领袖发表2018年新年贺词。贺词中提到，2017年，他又收到很多群众来信，其中就有南开大学新入伍的大学生，大学生们的故事让他深受感动，同时让他感到幸福都是奋斗出来的。最高领袖主席去年9月23日在给南开大学8名入伍大学生回信中，勉励他们把热血挥洒在实现强军梦的伟大实践中，书写绚烂、无悔的青春篇章。

　　Eight Nankai students are ordinary members of Qian Qian’s 10 million new college students in 2017. Among the eight people, some are the children of Xinjiang’s anti-terrorism martyrs, some are descendants of veterans who fought against US aggression and aided Korea, both urban youth and peasant children. Today, they have all grown up obviously: Kazakh boy Ashar, "challenged" to be the platoon leader of special warfare players for six years and completed the 3000-meter run in 11 minutes and 30 seconds; Dai Rui, a female soldier, changed from a "cute girl" on campus to a "female man" in a military camp. In order to cultivate a tall and straight military posture, she put paper on her knees and bricks on her head; Dong Xudong, the champion of the local college entrance examination, went from "Xueba" in the university to "Young Eagle" in the new training. After putting on his uniform, he read "The Educated Youth of the Supreme Leader" for the first time. Hu Yifan, a descendant of the Volunteers, not only learned, taught and applied theory in the military camp, but also hit the 48th ring &hellip with five shots at a distance of 100 meters. …

　　Key point two: the continuous development of national defense mobilization level will improve the ability of science and technology to participate in the war and support the front.

　　National defense mobilization is a bridge to transform national defense potential into national defense strength and an important content of national defense construction. The effectiveness of national defense mobilization construction is related to national security and development, and to the victory or defeat of future wars.

　　In 2017, with the adjustment of the whole army to form 84 military units, including services and arms units and provincial military region systems, various reform measures of the national defense mobilization system gradually landed and achieved new breakthroughs.

　　Planning and design are clearer. Combined with the formulation of the "Thirteenth Five-Year Plan" for national defense mobilization construction, the long-term tasks of national defense mobilization in 2025 and the indicators of core mobilization ability are demonstrated and put forward. Various strategic directions, mobilization fields and provinces (autonomous regions and municipalities) have also formulated various planning plans at different levels.

　　Accelerate the transformation of the construction model. Vigorously promote the transformation of national defense mobilization from quantitative scale to quality and efficiency, from ensuring army operations to ensuring joint operations of services and arms, from corresponding construction to complementary construction, and from extensive mobilization to precise mobilization.

　　The field of mobilization continues to expand. Adhere to information-oriented, increase preparations for supporting and ensuring the mobilization of services and arms, strengthen the construction of new mobilization forces such as information support, electromagnetic spectrum, meteorology and hydrology, mapping and navigation, medical rescue, and maintenance of high-tech equipment, actively explore expansion in various fields, improve the ability of science and technology to participate in wars and support the front, and lead national defense mobilization to a higher level.

　　At the same time, in order to meet the requirements of the reform of the military leadership and command system, the National Defense Mobilization Department of the Military Commission has guided Jiangsu, Guangdong, Fujian, Hunan and other provinces and military regions to carry out relevant pilot work, and made useful explorations in building a wartime mobilization organization and command mechanism, a mobilization demand reporting and docking mechanism, and establishing and improving a mobilization preparation inspection and evaluation system.

　　Focus 3: There are many preferential policies for resettlement of retired soldiers and entrepreneurship and employment.

　　The State Council and the Central Military Commission promulgated the Regulations on Resettlement of Retired Soldiers in October 2011. The Regulations specify a series of preferential policies for resettlement and entrepreneurship of retired soldiers.

　　Eligible retired soldiers can be arranged by the government. Non-commissioned officers have served in active service for 12 years; During the period of active service, he usually won a prize above Class II or a prize above Class III in wartime; Disability due to war is rated as level 5 to level 8 disability; Children of martyrs will be arranged by the people’s government.

　　Retired soldiers who are self-employed enjoy a series of support policies. If conscripts and noncommissioned officers who have been in active service for less than 12 years retire from active service, the people’s government will support their own employment and get a one-time retirement pension for their own employment; Local governments at or above the county level should support retired soldiers to find jobs and start businesses, and give tax incentives in accordance with state regulations; Employers recruit retired soldiers and enjoy tax incentives according to law; The land contracted by self-employed retired soldiers through household contract before joining the army shall not be illegally recovered or forcibly transferred during the contract period.

　　College soldiers enjoy a series of preferential treatment after retirement. Ex-soldiers who have been admitted to ordinary colleges and universities before enlisting and retained their qualifications for admission or are studying in ordinary colleges and universities are allowed to enroll or resume their studies within two years after retiring from active service, and enjoy preferential treatment such as scholarships, grants and tuition reduction and exemption in accordance with relevant state regulations. Those who apply for graduate students can enjoy the "special postgraduate enrollment plan for retired college students and soldiers" of the Ministry of Education.

　　Eligible retired soldiers can retire or be supported by the state. The living, housing and medical care of retired non-commissioned officers shall be guaranteed in accordance with the relevant provisions of the state. Conscripts and junior noncommissioned officers who have been assessed as disabled at level 1 to level 4 are discharged from active service and are supported by the state for life.

　　Military service registration is a mandatory obligation.

　　In fact, many people don’t know what military service registration is, and think that I don’t have the will to be a soldier, so I don’t need to go to military service registration. However, this is not the case. Article 13 of China’s Military Service Law stipulates that the state practices the military service registration system. Every year before December 31st, male citizens who have reached the age of eighteen shall go to military service registration before June 30th of that year according to the arrangement of the military service organs of counties, autonomous counties, cities and municipal districts.

　　According to the relevant regulations, military service registration is the registration management for citizens who meet the military service age, and it is a compulsory obligation of the state. Male citizens of the appropriate age who do not intend to join the army for the time being must also undergo military service registration and verification. Military service registration, mainly to prepare for the annual conscription work. That is to say, it is not necessary to join the army after military service registration.

　　Avoiding registration is responsible for affecting credit reporting.

　　Evading or rejecting citizens of military service registration will not only affect their normal participation in the army, but will also be subject to administrative punishment. According to the provisions of the Military Service Law, if a citizen who applies for enlistment refuses, evades the solicitation and refuses to make corrections, he shall not be employed as a civil servant or a staff member managed according to the Civil Service Law, and shall not go abroad (territory) or pursue further studies within two years. If the refusal to perform relevant obligations in wartime constitutes a crime, criminal responsibility shall be investigated according to law. (Feng Renqing)

The company’s 2023 annual report recently disclosed by Kexing Pharmaceutical shows that the company achieved an operating income of 1.259 billion yuan, down 4.32% year-on-year, a net profit loss attributable to listed shareholders of 190 million yuan, and a non-net profit loss attributable to shareholders of listed companies of 201 million yuan.

The loss in 2023 is also the second year since 2022 that Kexing Pharmaceutical has fallen into a loss, and the amount of loss has intensified. The annual report disclosed by Kexing Pharmaceutical also shows that the company invested 345 million yuan in research and development in 2023, setting a new high since its listing. However, although R&D investment continued to increase, Kexing Pharmaceutical not only failed to turn losses, but further increased its losses. The turnover rate of scientific research personnel in Kexing Pharmaceutical is around 21.63%, and in 2023, the company lost half of its doctors.

Addition and subtraction of doctor introduction and loss

The data shows that in 2023, the company introduced 17 new doctors, and the number of doctors in 2022 was 25. However, the number of doctors disclosed in the company’s 2023 annual report was only 20. In other words, although 17 doctors were introduced, 22 doctors left the company in 2023, which means that 17 postdoctoral doctors were introduced and half of them left Kexing Pharmaceutical in 2023.

How does Kexing Pharmaceutical, which relies on high-end talents for drug research and development, maintain innovation in research and development? What are the hidden dangers behind the abnormally high turnover rate of high-end talents?

Except for doctors, the overall number of R&D personnel of Kexing Pharmaceutical is in a state of substantial loss. The data shows that in 2022, the number of graduate students in the company was 87, and in 2023, the number of graduate students has been reduced to 79; In 2022, the number of R&D personnel with bachelor’s degree was 72, and in 2023, the number of R&D personnel with bachelor’s degree was only 53; In 2022, the number of R&D personnel with junior college or below was 24, and in 2023, it has dropped sharply to 11.

In 2022, there were 208 R&D personnel in the company, and in 2023, the number of R&D personnel in the company has been reduced to 163, a year-on-year decrease of 21.63%. In 2020 and 2021, the number of R&D personnel in the company was 170 and 194 respectively. In 2023, the number of R&D personnel of the company also hit a new low since listing.

R&D investment has reached a new high, but R&D personnel have been greatly lost and net profit has been greatly lost. For example, Kexing Pharmaceutical has fallen into a strange circle of more R&D investment and more losses this year.

The R&D investment of listed companies in the same industry disclosed in the company’s research report shows that the R&D investment of Tebao Bio, Sihuan Bio, Sanyuan Gene, Wan Ze Co., Ltd. and Cain Technology accounted for 13.33%, 14.42%, 20.65%, 16.68% and 12.22% of the operating income respectively, while the R&D investment of Kexing Pharmaceutical accounted for 27.4% of the operating income in 2023.

Overseas commercialization is not effective only by shouting.

The annual report disclosed this time also exposed the embarrassing reality of the company’s overseas commercialization strategy.

The annual report shows that the company’s export revenue in 2023 was 138 million yuan. Compared with 2022, the company’s export revenue did not rise but fell. In 2022, the company achieved overseas sales revenue of 161 million yuan, an increase of 61% over the same period of last year, setting a record high.

Kexing Pharmaceutical once regarded overseas commercialization as an important strategy, and the company indicated that it would devote itself to building the most valuable overseas commercialization platform in China. However, in three years, the company’s export income still accounts for only about 10% of the company’s operating income.

As early as 2021, Kexing Pharmaceutical introduced albumin paclitaxel, and obtained the technology of albumin paclitaxel and its commercial rights except the American market. However, albumin paclitaxel has only recently passed the GMP certification of the European Union, and if the drug goes on the market, it needs to be approved by the European Union Marketing Permit Application (MAA).

Although the company has introduced a total of 12 products, signed contracts with customers in more than 40 countries and submitted applications for registration of imported products, it still seems that it has not been sold in overseas markets. "infliximab, bevacizumab, albumin paclitaxel and other products have successively completed on-site audits in Egypt, Brazil, Indonesia, the European Union and other countries, and it is expected that overseas sales of the above products will be realized in 2024.

On the evening of May 24th, Kexing Pharmaceutical released the 2024 restricted stock incentive plan (draft). The number of restricted shares to be granted is 3.786 million shares, with a total of 147 people to be encouraged.

The assessment year of this incentive plan is two fiscal years from 2024 to 2025, and it is assessed once in each fiscal year. Taking the company’s overseas sales revenue in 2023 as the performance base, the growth rate of overseas sales revenue in each assessment year or the cumulative number of overseas registration documents was assessed. Based on the overseas sales revenue in 2023, it is planned that the growth rate of overseas sales revenue will be 50%-100% in 2024 and 200%-400% in 2025.

In 2023, the company’s export revenue will decline instead of rising, but in 2025, the overseas sales revenue will increase by two to four times. Although the vision of Kexing Pharmaceutical is beautiful, it still has a long way to go.

　　Sanyuanli vegetable market in Chaoyang District is neat and standardized, clean and hygienic, with complete products. Because it is close to the embassy district, it also attracts many foreigners to buy it. Reporter Deng Wei photo

　　Reporter Ma Jing

　　Just after 9: 00 a.m., Sanyuanli vegetable market became lively. Chefs from western restaurants came to buy lunch ingredients, young mothers picked imported fruits, and takeaway brothers walked quickly through busy delivery. Delicious vegetables, colorful fruits, seafood from all over the world, and strange spices … … Although this vegetable market with an area of only 1,560 square meters is small, it is full of all kinds of delicious food from all over the world.

　　In the vegetable market, a long and narrow passage runs through the north and south, with 140 merchants on both sides. In a booth of only a few square meters, merchants set up a ladder with a simple frame to place dishes, and the layered vegetables will be surrounded by vegetable sellers, who can only drill in and out from the corner of the ladder.

　　For 59-year-old Li Xueling, loading goods is a manual job, but she enjoys it. Before dawn, her whole family drove to major wholesale markets to select fresh "sharp goods". After being transported back to the vegetable market, they had to choose dirty leaves, wrap them in plastic wrap, and put them on the stalls after some initial processing. "The morning is the busiest and most chaotic time, but the market is neat as soon as it opens." Li Xueling said.

　　"Elder sister, give me a small box of sweet beans and a catty of tomatoes." Just opened, Ms. Sun, an old customer, appeared in front of the booth in Li Xueling as usual. The price of two vegetables of nearly 100 yuan did not surprise Ms. Sun. After skillfully scanning the code to pay, she picked up the bag and walked to the fruit stand.

　　What attracts Ms. Sun is that there are always unexpected gains here. A kilo of organic tomatoes in 20 yuan, Japanese pumpkins that are often sold out of stock, Brussels sprouts that look like mini cabbages, and delicious flowers with high value … … The small vegetable market is an eye-opener and makes people enjoy the beauty of food.

　　"Who would have thought 30 years ago that there are so many kinds of vegetables now?" Li Xueling remembered that she and her husband came to Beijing from their hometown in Baoding, and each of them joined the army of selling vegetables with a flatbed. At the beginning, all the stalls were the same road dishes, with only five or six varieties. At that time, she didn’t expect that such a "online celebrity" vegetable market could be built on the grassland that she passed every day when she went home.

　　In 1992, before and after the country completely abolished the policy of residents buying pork by ticket, vegetable greenhouses were built in Sanyuanli vegetable market, and roadside vendors pushed carts into the market to set up stalls. Since then, this old vegetable market has undergone many upgrades and hardware upgrades, and it has also evolved into an international vegetable market full of emotional appeal.

　　If the opening is the right time, internationalization is the right place. Because of its proximity to the embassy district, Sanyuanli vegetable market has attracted customers from all over the world, and various demands have also made merchants smell business opportunities. This vegetable market, which takes two or three minutes to walk quickly, has gradually become a "fresh United Nations".

　　Yesterday evening, Liu Rong, a white-collar worker who just finished working overtime, walked into Sanyuanli vegetable market and went straight to a cheese shop, with black lemon cheese and colorful red sauce cheese … … Liu Rong, who just learned to cook western food, was dazzled.

　　"I have no cheese you can’t find." Shop owner Wen Guochen is full of confidence. Twenty-two years ago, he was a vegetable merchant in the market. Because many foreigners who came to buy food could not find their own cheese, Wen Guochen decided to change careers. He asked the import agent to collect all kinds of cheese and spices to satisfy the stomachs of foreign customers. In recent years, more and more Chinese began to patronize his small shop, and the business was getting better and better.

　　Just after seeing off the customers, a fashionable food anchor walked into the store, aimed the camera at the cheese in the freezer, and the screen of the mobile phone flashed with questions from fans. For such a scene, Wen Guochen has long been accustomed to it. In recent years, artists have come to hold exhibitions, writers have come to hold new book conferences, and economists have come to hold small classes in economics. The unique "online celebrity" temperament makes this vegetable market bring people endless imagination.

　　Li Xueling felt that in the past two years, the number of passengers in the vegetable market has decreased, but the micro-shops in mobile phones have become busier. "When someone visited once, they added WeChat. When it is inconvenient to come, they will place an order online." Like Li Xueling, merchants have been operating mobile phone markets. The take-away and flash delivery staff who shuttle through the market have also become a unique landscape.

　Fan Chunhai is a member of the Central Committee of Jiu San Society, a professor at the School of Chemistry and Chemical Engineering of Shanghai Jiaotong University, and a member of the Shanghai Municipal Political Consultative Conference. In 2019, he was co-elected as an academician of China Academy of Sciences.

At the age of 26, he received a doctorate in biochemistry and molecular biology from Nanjing University.

At the age of 33, he was supported by the Outstanding Youth Fund of the National Natural Science Foundation of China.

At the age of 42, his team developed a new method for inducing nano-scale precise mineralization by DNA self-assembly structure, which was published in Nature, and achieved the first breakthrough in the field of DNA nanotechnology by China researchers.

He has been selected as a "highly cited scientist in the world" in the past six years.

At the age of 45, he was elected as an academician of China Academy of Sciences, the youngest among the Shanghai academicians in 2019.

He is Fan Chunhai, member of the Central Committee of the Jiu San Society, member of the Shanghai Municipal Committee of the Chinese People’s Political Consultative Conference, and director of the Shanghai Municipal Committee of the Jiu San Society.

Fan Chunhai’s office is located in the Translational Medicine Research Center of Shanghai Jiaotong University. Next to the simple and bright office is a uniform laboratory. The experimental platform is filled with all kinds of equipment. The window is bright and clean, with few other colors except black and white. Fan Chunhai, who has just been interviewed by his alma mater, is still immersed in the memories of middle school life. Talking about today’s achievements, he said with emotion: "These 20 years happened to be a period of rapid development in China, and the conditions and level of scientific research have undergone tremendous changes. I am glad to catch up with such a good era and let me make great achievements in scientific research."

Fan Chunhai belongs to the Ministry of Chemistry in the published results of the co-election of academicians of China Academy of Sciences. He once won the Tan Jiazhen Prize for Innovation in Life Sciences, one of the most influential awards in the field of life sciences in China. After returning to China, he chose the Shanghai Institute of Applied Physics of Chinese Academy of Sciences as his work unit. Under such a "cross-border", it seems difficult to define his professional field. His explanation for this is: "Subject field and research direction are different concepts, and my research direction has not changed for more than 20 years. I have been engaged in basic research on biosensing since I was a graduate student, just to explore the unknown world and need a broader vision. "

In 1992, Fan Chunhai, who was preparing to take the college entrance examination, applied for the Department of Biochemistry of Nanjing University. "At that time, the choice of biochemistry was blind and I didn’t understand it at all. But I vaguely feel that biochemistry has both biology and chemistry. This name is cool! " Fan Chunhai recalled.

樊春海在南京大学读书时，生物化学系就有浓郁的学科交叉氛围，系里的口号是“学不好化学，就做不好生物化学”。我国生物制药技术研发的开拓者之一，肝素、尿激酶工业的创始人朱德煦时任系主任，中国科学院院士、生命分析化学概念的创导者和生命分析化学国家重点实验室创始人陈洪渊的博士李根喜在生物化学系任教，樊春海在研究生期间得到他们的指导，在生物化学和生命分析化学两条学术传承线的交叉点起步，从事电化学生物传感器的研究，这在当时属于前沿交叉学科。

在前沿学科里不断前进，必须更多地了解国际上的科研动态，“我读书那会儿，经常需要看国外文献，遗憾的是那时看到的文献会滞后至少半年。”樊春海偶然读到《先进材料》（Advanced Materials）杂志对圣塔芭芭拉加州大学（UCSB）艾伦？黑格（Alan J. Heeger）教授（诺贝尔化学奖获得者）的专访文章。文章中黑格表示，自己在获诺贝尔奖后希望做一些以往不敢做的事，比如生物学，特别是生物传感方面的研究。樊春海内心有种一拍即合的快感，随即就向黑格教授申请了博士后，并最终获得认可。

Allen? Haig is a professor in the Department of Physics, but he always advocates interdisciplinary research. Many years later, Professor Haig said modestly in a speech in China: "I knew nothing about biology at that time, even the most basic knowledge such as DNA molecular structure was taught by Chunhai."

"Studying in a Nobel Prize winner’s laboratory, the vision of seeing problems and the way to deal with problems are very different from those in an ordinary laboratory." Fan Chunhai admits that when he was working as a postdoctoral fellow, he realized a deeper connotation about interdisciplinary. Working in Haig’s laboratory, Fan Chunhai had to carry out multiple scientific research projects at the same time, which once overwhelmed him. "You just pick the most important thing to do." This sentence of the tutor made Fan Chunhai enlightened, and he still often guides him to make judgments.

Under the guidance of Professor Haig, Fan Chunhai has made some research progress, and related research work has been published in authoritative magazines such as Proceedings of the National Academy of Sciences (PNAS) and Journal of the American Chemical Society (JACS). Among them, an electrochemical DNA biosensor named E-DNA has been developed, which has been widely praised by international peers. American Chemical Society C&E News rated it as one of the important chemical progress in 2003.

The postdoctoral experience has greatly broadened Fan Chunhai’s horizons and strengthened his confidence in interdisciplinary research. At that time, China was in the initial stage of discipline construction and needed a lot of new blood. In January 2004, Fan Chunhai joined sinap with the support of the "Hundred Talents Program" of China Academy of Sciences. Coincidentally, the day when he joined the defense was the day when the Shanghai Synchrotron Radiation Light Source Project undertaken by the Institute was approved after ten years of hard preparation. This internationally advanced synchrotron radiation light source was completed in only five years. The scientists who participated in the project are not afraid of hardships and hard work, and are praised as "Shanghai Light Source Spirit". In the past five years, under the inspiration of "Shanghai Light Source Spirit", Fan Chunhai built a laboratory from scratch.

In 2008, Fan Chunhai and others established a physical biology laboratory and set up a multidisciplinary research team integrating physics, chemistry and biology. This unique interdisciplinary research atmosphere not only enabled the biosensor research to advance rapidly, but also broadened more frontier research directions. In 2016, the important achievement of the laboratory, "Research on Mechanism, Regulation and Application of Biomolecular Interface", won the second prize of National Natural Science.

In recent years, Fan Chunhai’s team has applied biosensing probes detected in vitro to cells, and is committed to developing frame nucleic acid cell imaging technology. "It doesn’t matter what technology you use, physics or chemistry, or nanotechnology. What matters is that you find some new methods and use some new technologies to observe and decipher the mysteries of life."

"Individual growth cannot be separated from excellent collectives"

Fan Chunhai always appreciates the strength of the collective. Whether it is the study and life in middle schools and universities or the scientific research work, Fan Chunhai believes that the excellent collective has given him the motivation for personal growth.

He recalled that he was never the best student in middle school. "I am a person who knows by learning, not a person who knows by birth." In high school, many of my classmates were excellent. Everyone always discussed problems harmoniously and equally, forming a rich learning atmosphere. Under the professional guidance of teachers, everyone was growing and making progress. In the end, the whole class handed over an excellent answer sheet in the college entrance examination. "

There is such a collective star effect in scientific research, such as the famous Cavendish laboratory, which has trained more than 20 Nobel Prize winners in the past 100 years. "So scientific research has never been alone, and the progress of each group cannot be separated from individual efforts, and the growth of individuals cannot be separated from an excellent group." Fan Chunhai said.

At the beginning of this century, the scientific research conditions in Chinese universities were still relatively difficult, and the information was not as developed as it is now. It was the dream of many analytical chemists in China to be able to publish papers in Analytical Chemistry in the United States. At that time, only Mr. Chen Hongyuan in Nanjing University published papers in this magazine. Fan Chunhai published a paper in Analytical Chemistry as the first author under the guidance of his tutors, and achieved a breakthrough.

Interdisciplinary cooperation is also inseparable from the cooperation between scientists and the whole team. Fan Chunhai, deeply inspired by the "Shanghai Light Source Spirit", hopes to do the same internationally influential research work in Shanghai Institute of Applied Physics, Chinese Academy of Sciences. Mr. Li Mingan and researcher Hu Jun are early explorers in the cross-research of nano-organisms in China. With their guidance and help, Fan Chunhai gradually made it clear that DNA nanotechnology is the starting point to form research characteristics.

DNA nanotechnology is to use the excellent self-assembly and recognition ability of DNA molecules as a nano-material to achieve accurate nano-construction. In 2006, the nano-scale "Map of China" assembled by DNA molecules was successfully created and published in both Chinese and English editions of Science Bulletin, which made an international appearance with China characteristics and became the second published work in the frontier cross field of "DNA origami", which was jointly completed by Fan Chunhai, Hu Jun and Academician He Lin of Shanghai Jiaotong University.

After years of accumulation, Fan Chunhai’s team developed a new method to induce nano-scale precise mineralization by DNA self-assembly structure, which improved the mechanical properties of DNA nano-structure while maintaining its exquisite design, and opened a new door for the construction and analysis of bionic nano-channels. This research achievement was published in the journal Nature, which achieved the first breakthrough in this field by researchers in China.

During the epidemic in COVID-19, due to the lack of Covid-19 RNA reference materials, the performance of nucleic acid detection kits could not be evaluated, and the competitiveness of high-quality domestic kits could not be strongly proved. Faced with this situation, with the deep participation and support of Fan Chunhai’s team, Shanghai Jiaotong University and Shanghai Institute of Metrology and Testing Technology jointly set up a research team and started the research and development project of Covid-19 RNA reference materials. After more than 40 days of repeated trials and improvements, two kinds of "novel coronavirus standard materials for RNA transcription in vitro" were successfully developed. These Covid-19 reference materials, like a "biological standard ruler", can help people to evaluate the indicators of the virus nucleic acid detection kit and help the detection laboratory to confirm the results, thus further reducing the probability of "false negative".

Facing the students from different majors in the team, Fan Chunhai advocates teaching students in accordance with their aptitude and effective guidance. "Students are not managed, but grow up freely under appropriate guidance. My task is to tap students’ interest in scientific research, help them establish correct values and lofty aspirations, and become firm supporters of students."

The road of scientific research has always been bumpy. The life of researchers is more like an ascetic monk to many people, but in their hearts, they are happy because of their love for science. In Fan Chunhai’s view, this happiness is not equal to comfort. He encourages students: "To do scientific research, we should be brave enough to go out of our comfort zone and challenge new things."

"Teamwork and independent thinking are equally important. I hope that every student can choose his own topic under the background of team research, and actively explore various possibilities without relying on authority." Despite his busy work, Fan Chunhai will try his best to take time to communicate with the students face to face, not sitting in danger, but full of relaxation and pleasure.

Fan Chunhai always tries his best to support and encourage students’ decisions and every attempt. Under his training, two students have been supported by the National Science Fund for Distinguished Young Scholars, and four postdoctoral students have been selected for the "Super Postdoctoral Program" in Shanghai in 2020.

Communication and cooperation promoted Fan Chunhai’s scientific research work, and also made him know Li Xinxin, chairman of the Shanghai Branch Committee of the Shanghai Municipal Committee of the Chinese Academy of Sciences of the Jiu San Society. The warmth of the Jiu San Society and the spirit of patriotism, democracy and science attracted him. In 2014, he joined the Jiu San Society.

After joining the club, Fan Chunhai successively served as deputy director and director of the Shanghai Municipal Committee of the Jiu San Society. Although his scientific research work is still busy, he will still find time to engage in popular science work. "Popular science work is actually a kind of inheritance. Whether it is exploring the unknown world or promoting the country’s scientific and technological development, it needs the efforts of generations. However, the concept of scientific research is not exactly the same as that of textbook education in primary and secondary schools. Our popular science work is not a simple strengthening of textbook knowledge, but a broader vision for children. "

In his mind, interests are hierarchical. The interests of primary and secondary school students are often in textbook knowledge and the use of known world knowledge, while real scientific talents need to keep their interest in exploring the unknown world. Spreading the seeds of science in children’s little hearts will not only keep them interested in exploring the unknown world, but also make the city form an atmosphere of obeying and respecting science, which is also the future light of the construction of Shanghai Science and Technology Innovation Center.

Looking back on his own growth experience, Fan Chunhai said with emotion: the cultivation of quality is more important, and the knowledge learned by the school is constantly updated, and the quality cultivated by the school will accompany people all their lives, and good quality will push people forward.

Good quality also made Fan Chunhai on his way to school recognized by teachers. "I am very relieved about what I have told him. No matter whether I get satisfactory results or lessons from failure after completion, he will definitely reply to me and have a serious discussion with me." Professor Li Genxi said of his students, "He is patient in learning and can hold his breath. Once his goal is set, he will be firm and forge ahead. His success is no accident."

In the interview, Fan Chunhai rarely talked about specific difficulties, because he believed that difficulties always existed, and problems could be solved as long as he worked hard and was good at learning and observing. In the communication with his students, Fan Chunhai has always conveyed a belief: optimistic and unyielding. "The development of science is not a full stop, but a comma. The success of scientific research depends on whether you have the courage to face failure and the determination to be more frustrated on the road of exploration. I hope that all students can work hard for the scientific dream of mankind."

It has been nearly thirty years since I entered the university and contacted the interdisciplinary subject of biochemistry. Along the way, Fan Chunhai has grown from an ignorant teenager to an internationally renowned scientist: he was selected as a Fellow of American Association for the Advancement of Science (AAAS), American Academy of Medical and Biological Engineering (AIMBE), international society of electrochemistry (ISE) and royal society of chemistry (RSC), and concurrently served as the deputy editor of ACS Applied Materials & Interfaces Journal of American Chemical Society. Co-chairman of the editorial board of ChemPlusChem, royal society of chemistry, has been selected as a "global highly cited scientist" continuously since 2014. In 2019, he was elected as an academician of China Academy of Sciences, and won the ho leung ho lee foundation Science and Technology Innovation Award, the American Chemical Society’s Lecture Award for Progress in Measurement Science and the 12th Tan Jiazhen Life Science Innovation Award, and in 2020, he was awarded the title of "National Advanced Worker".

Faced with many honors, Fan Chunhai said calmly: "It is curiosity, responsibility and initial heart that lead me to climb to the peak on the road of science." In the future, he said that he will continue to keep his initial heart and forge ahead, lead students to "look up at the stars, be down-to-earth, persevere and make contributions for a long time", constantly explore the frontiers of science, and make due efforts to promote the scientific and technological progress of the country and society.

Fan Chunhai’s goal is to promote his basic research work to clinical application and protect human health. After joining the School of Chemistry and Chemical Engineering of Shanghai Jiaotong University, Fan Chunhai built the laboratory of "Framework Nucleic Acid Design and Nano-medical Diagnosis and Treatment" based on the newly completed national major scientific and technological infrastructure of translational medicine, and devoted himself to transforming and applying the developed new methods of nucleic acid analysis and detection to clinic. In particular, he received the full support of Academician Tan Weihong, Dean of the Institute of Molecular Medicine of Shanghai Jiaotong University, and actively carried out clinical cooperation in Renji Hospital, trying to apply biosensors to the detection of practical clinical samples such as prostate cancer, and exploring the possibility of developing low-cost medical detection.

"The road is long and Xiu Yuan is awkward, and I will search up and down." Fan Chunhai is still moving forward on the road of seeking. In 2019, in order to commemorate the tenth anniversary of the publication, "Nature? The magazine Nature Chemistry specially invited more than 50 internationally renowned scholars to write a monograph on "The Road to Chemistry". As one of them, Fan Chunhai raised a challenging question in the field of chemistry: "An exciting frontier of the discipline is to understand how artificially designed nucleic acid structures are assembled and function in living cells and animals. Creating new tools to control the assembly process of natural and artificial nucleic acid molecules in living cells will probably bring revolutionary changes to the field of nucleic acid chemistry, thus promoting the development of nano-diagnosis and treatment and precision medicine. In the longer term, another promising research direction is to explore and develop DNA or RNA robots with artificial intelligence and work in animals and humans. " (Huang yun)

　　There are three ways to upgrade the sogou input method: 【 Manual Update 】 means not to update, and click 【 Update Now 】 to update yourself. [Prompt Update] is to prompt when there is a new version. Automatic update is to download and install the updated new version automatically when a new version is found.

　　Sogou input method is a Chinese Pinyin input method recently launched by Sohu, which is a great breakthrough compared with Intelligent ABC and Microsoft Pinyin input method. First of all, it has increased a lot in the thesaurus. The sogou input method includes the most popular phrases, including the names of famous stars, into the thesaurus by analyzing a large number of web pages, so that the phenomenon that commonly used phrases can’t be typed is no longer seen. Secondly, the interface has also been greatly improved. Chinese characters will be automatically displayed below the typed letters, and it is no longer necessary to press the space bar. More convenient input and faster typing speed are the main features of sogou input method.

　　Sogou input method is different from the traditional method in that it adopts search engine technology, which is the second generation input method. Thanks to the adoption of search engine technology, the speed has made a qualitative leap, and sogou is far ahead of other input methods in terms of the breadth of thesaurus and the accuracy of words.

　　The biggest feature of sogou input method is the combination of input method and Internet. The input method will automatically update its own popular thesaurus, which is derived from the popular keywords of sogou search engine. In this way, the workload of users’ self-created words is reduced and the efficiency is improved.

In the 1970s, the international situation changed rapidly, and a new situation appeared in China’s foreign relations. In 1974, Mao Zedong made a new judgment on the international pattern and put forward a strategic idea of dividing the three worlds.

From a "middle zone" to "two middle zones"

The strategic thought of dividing the three worlds contains profound thinking and long-term exploration of the international pattern, which comes from the theory of "middle zone"

Regarding the division of international pattern, Mao Zedong first put forward a theory of "middle zone". After World War II, the relationship between the United States and the Soviet Union deteriorated, and a full-scale civil war broke out between the Kuomintang and the Communist Party. It was impossible for Mao Zedong to put China on the road of new democracy through peaceful and democratic means. At the critical moment of the situation transformation, Mao Zedong put forward the theory of "two camps" and "one middle ground" in the summer of 1946. He believes that the post-war world is divided into a peaceful and democratic camp headed by the socialist Soviet Union and a reactionary camp headed by American imperialist forces; There is a vast middle zone between the United States and the Soviet Union, which is composed of many capitalist countries and colonial and semi-colonial countries in Europe, Asia and Africa. The realistic problem facing the world after the war is that the United States is trying to control and invade countries in the middle zone, including China. This theory makes a unique division of various international political forces, points out China’s position in the world, and clarifies the relationship between friends and enemies of the China Revolution in the world. Since then, when the China Revolution is about to win, this theory naturally leads to the conclusion of "one-sided" to the socialist Soviet Union.

Since then, with the changes in the international situation and surrounding environment, Mao Zedong has put forward the strategy of "two intermediate zones". In the early 1960s, the international movements of countries in Asia, Africa and Latin America against imperialism and colonialism, striving for and safeguarding national independence continued to rise, and the internal contradictions in the capitalist world continued to develop. Judging from China’s foreign relations, Sino-US relations continue to be tense, and Sino-Soviet relations are on the verge of rupture. From the end of 1963 to the beginning of 1964, Mao Zedong put forward the strategy of striving for "two intermediate zones". He divided the "middle zone" into two parts, one part refers to the underdeveloped countries in Asia, Africa and Latin America, and the other part refers to capitalist countries and eastern European countries except the United States. Mao Zedong pointed out that these two parts are opposed to American control, while eastern European countries are opposed to Soviet control. Mao Zedong believes that in the process of confronting the two great powers, China should unite the two middle areas as much as possible. The strategy of "two intermediate zones" has relieved China’s external pressure to some extent. In 1964, China and France broke through the barriers of different ideologies and social systems and formally established diplomatic relations. During this period, China’s relations with African and Arab countries have also developed significantly.

The changes in Sino-US relations have caused a chain reaction.

In the early 1970s, the foundation of tripartite relations between China, the United States and the Soviet Union changed significantly, and the trend towards multipolarity in the world gradually emerged. Mao Zedong began to re-examine the new international situation and China’s foreign relations, and put forward the strategic idea of "three worlds" division.

Since the late 1960s, new changes have taken place in the international pattern. First of all, the balance of power between the United States and the Soviet Union has changed, from the dominance of the United States to a balance of power, and the position of the United States among Western allies has also weakened. Secondly, western Europe and Japan are gradually reviving, and the centrifugal tendency of eastern European countries towards the Soviet Union is also developing. Finally, China has gradually become an independent and important political force on the international stage, and the power and influence of other Asian, African and Latin American countries have also further increased. During this period, China’s foreign relations have undergone major changes. On the one hand, the border conflict between China and the Soviet Union in 1969 and the nuclear threat of the Soviet Union since then made Mao Zedong deeply feel the seriousness of national security issues. On the other hand, China and the United States began to ease their relations out of consideration for their respective national security. In the spring of 1971, "Ping-Pong Diplomacy" kicked off the relaxation of Sino-US relations. In February of the following year, President Nixon visited Beijing, and the process of Sino-American reconciliation started. In October 1971, the 26th United Nations General Assembly adopted a resolution to restore China’s lawful seat in the United Nations, and then the climax of the establishment of diplomatic relations between countries and China appeared. With the relaxation of Sino-US relations, the Soviet Union has become the biggest and most direct threat to China. In 1973, Mao Zedong put forward the strategic idea of "one line" and "one large area", hoping to establish a United front from Japan through Europe to the United States.

With the rapid development of international situation and China’s foreign relations, Mao Zedong put forward the strategic idea of dividing three worlds. In February 1974, when talking with Zambian President kaunda, Mao Zedong first put forward the strategic idea of dividing the three worlds. He pointed out: "I think the United States and the Soviet Union are the first world. The centrists, Japan, Europe, Australia and Canada, are the second world. We are the third world. " He also said: "The third world has a large population. Asia is a third world except Japan. All of Africa is the third world, and Latin America is also the third world. " According to the division of Mao Zedong, China belongs to the third world, so it is necessary to strengthen unity with third world countries and strive for unity with second world countries; Among the two superpowers in the first world, they mainly develop relations with the United States and concentrate on opposing the hegemonism of the Soviet Union.

On April 6, 1974, at the proposal of Mao Zedong, Deng Xiaoping led a delegation from China to attend the sixth special session of the United Nations General Assembly. This is the first time that a People’s Republic of China (PRC) leader has attended a United Nations meeting, which has attracted worldwide attention. On April 10th, in his speech at the conference, Deng Xiaoping comprehensively expounded Mao Zedong’s strategic thought on dividing the three worlds and China’s foreign policy. He emphasized that China is a socialist country and a developing country, and China belongs to the third world. The government of China and the people of China firmly support all the oppressed people and nations in their struggle for and maintenance of national independence, development of national economy and opposition to colonialism, imperialism and hegemonism. China is not and will never be a superpower. This has actually repositioned China’s international role and further clarified China’s corresponding international responsibilities.

Compared with the "two intermediate zones" strategy in the 1960s, the most obvious difference in the strategic thinking of the three worlds is to treat the Soviet Union at the same level as the United States. This change is based on the changes in the relations between China, the United States and the Soviet Union, uniting with the party that poses less threat to China and concentrating on preventing the main threat from China. In terms of ideological methods, the criteria for dividing the three worlds are no longer based on the nature of class and society, but mainly on comprehensive national strength. It enables people to clearly see the position of countries in the world in international political and economic relations.

Expanded the stage of China’s diplomatic activities.

The strategic thought of dividing the three worlds is the result of Mao Zedong’s long-term deliberation, which has great significance and far-reaching influence on China’s foreign strategy and foreign relations.

The strategic thought of dividing the three worlds is based on Mao Zedong’s scientific judgment on the international situation and accurate understanding of the international pattern. It is saturated with Mao Zedong’s long-term political experience in international struggle and is the development of Mao Zedong’s United front theory under the new situation. The strategic thought of dividing the three worlds reveals the main characteristics of the development of the world situation at that time and the basic pattern of the strength comparison among countries in the world, and determines China’s international status and strategic goals from the historical, realistic and strategic significance. This thought has long been the theoretical basis and main basis of China’s foreign strategy, and its role and influence continued until the disintegration of the Soviet Union, the disappearance of bipolar confrontation and the overall change of the original international pattern.

Under the guidance of Mao Zedong’s strategic thought of dividing three worlds, China’s diplomatic work has made a comprehensive breakthrough. China broke through the pattern of "two camps", implemented the policy of "one line" and "one large area", persisted in opposing the hegemonism and the threat of war of superpowers, worked hard to normalize Sino-US relations, actively improved relations with second world countries, and vigorously developed friendly cooperation with third world countries and other types of countries. From 1970 to 1976, China successively established diplomatic relations with 61 countries, and more than 110 countries established diplomatic relations with China, including most countries in the world at that time. This completely broke the diplomatic deadlock caused by China’s isolation and containment for a long time, greatly improved the international environment in China, and greatly expanded the scope of China’s diplomatic activities. At the same time, it also ensures that China can smoothly implement reform and opening up and participate in international affairs more extensively in the near future.
