Enhance the sense of innovation and do scientific research with taste.

Innovation is the key to scientific research. According to different research attributes, innovation has different types: original innovation, cutting-edge innovation, technological innovation, integrated innovation, applied innovation and so on. No matter what kind of innovation, the innovation subject needs to have innovative consciousness, put forward innovative ideas, carry out innovative practice and produce innovative results. Innovation consciousness is the premise of scientific innovation activities. Researchers should consciously enhance their innovation consciousness, not follow others’ advice, follow the crowd and chase hot spots, think independently, dare to be the first and find a new way, and on the basis of predecessors’ work, through profound insight, rich imagination, careful thinking and concrete practice, find problems, raise problems and then solve them.

Academician Gao Dingsan, the founder of the Institute of Electronics of Jida University, was keenly aware of the importance of semiconductor devices in the mid-1950s, and took the lead in developing high-power germanium rectifiers and point-contact germanium diodes in China, which started the research of semiconductor devices in China. This innovative consciousness and spirit can be passed down and carried forward among the new generation of young scholars. Professor Feng Li, winner of the National Outstanding Science Foundation and State Key Laboratory of Supramolecular Structures and Materials, used the solid physical and device foundation laid during his undergraduate and doctoral years in the School of Electronics and combined with his years of research practice in the field of organic optoelectronics, put forward and verified a new concept of organic electroluminescence with two-line exciton emission, which broke through the limitations of closed-shell molecules of organic electroluminescent materials, opened up a new field of free-radical open-shell molecular electroluminescence, and wrote a strong stroke for China scholars in the field of organic optoelectronics.

Innovation needs taste. Taste is awe of the profession, demanding of oneself and respect for peers. Taste also reflects the pride, persistence, perfection and craftsman spirit of researchers. Teachers in Jilin University should cultivate innovative consciousness, carry out tasteful research, contribute to mankind, serve the country, serve the society and achieve themselves.

Adhere to the spirit of seeking truth from facts and do meaningful scientific research.

Seeking truth from facts is the key to scientific research. Seeking truth is to pursue scientific truth, discover real phenomena, obtain real data, reveal the essence and connotation of science, and then expand the boundary of human cognition, and use it to transform the world and make it a better place. The process of seeking truth from facts is a painful and happy one, and this process will inevitably encounter many difficulties and challenges, some of which are confusion of thinking methods, some are lack of hardware conditions, and some are shortcomings of the research team. However, no matter what kind of situation you encounter and what kind of situation you are in, as long as you are realistic and do not change your mind, you will open roads and bridge rivers, overcome all kinds of difficulties and obstacles, and finally reach the other side of scientific truth.

Jilin University has an academic tradition of seeking truth from facts, and the old president of Tang Aoqing is a model of seeking truth from facts. In 1986, Mr. Tang Aoqing stepped down as the principal and became the director of the National Natural Science Foundation of China. In addition to his busy management work, he still insisted on the research of polymer solidification theory and scale. In five years, he wrote 104 personal letters to his collaborators and doctoral students in Beijing to discuss the progress of research and the problems he encountered. As early as 1960s, Mr. Tang Aoqing got the sol-gel distribution formula by using the theory of dynamic random branching, and he wanted to get the polymer solidification theory on this basis. However, when dealing with the problem of internal Aa cross-linking, Mr. Tang found the shortcomings of previous work. In his letter to his collaborator, he wrote: "I found that there was an error in the previous derivation of the problem of internal Aa cross-linking. I was aware of this problem when I visited West Germany. After reading your letter, the problem became clearer. I re-derived the formula and attached it. Please ask Comrade Zesheng to do some concrete calculations and verify it to see if it is correct." (Quoted from Tang Aoqing and His Disciples, Xiamen University Press, November 2015, p. 161) Between the lines, Mr. Tang’s scientific spirit of seeking truth in learning is reflected, which is a model for our people to learn, and a scholarly character and spiritual wealth that Jilin University should cherish and inherit.

Professor Liu Shiying, the late famous optoelectronics scientist in the Institute of Electronics, is also a good teacher who is realistic. Mr. Liu is a founding veteran of the Institute of Electronics and one of the founders of the State Key Laboratory of Integrated Optoelectronics. He has made outstanding research achievements in integrated circuits, semiconductor lasers, integrated optoelectronics and organic optoelectronics. He is not only active in thinking, rigorous in academic research, and realistic, but also teaches young teachers and students by example. Whenever young teachers and graduate students report on their scientific research work, Mr. Liu will ask about the details of the experiment and the physical nature of the experimental phenomenon. The young teachers and graduate students who were questioned felt humiliated and embarrassed at that time. However, after they calmed down, they will feel that this kind of realistic style of study is very important, and they will strictly demand themselves and then teach them to their own students, gradually forming a rigorous and realistic style.

Stick to academic integrity and be a convincing good scholar

Academic integrity is the life of academics and also the life of scholars. Academic misconduct or academic anomie not only destroys the atmosphere of academic community, leads to the prevalence of unhealthy trends, but also misleads and interferes with the research of other scholars. If papers based on false data are published, peer scholars will track, repeat and verify these results. When they don’t get the same or similar results, peer scholars will first suspect that there is something wrong with their own experimental methods or details, thus spending a lot of time, energy and resources to repeat experiments, resulting in a lot of waste of time and resources, which is a direct damage to peer scholars. Therefore, adhering to academic integrity is the basic requirement and professional bottom line of scientific research teachers.

In recent years, the alienation tendency of evaluation criteria has led to impetuous wind. Aiming at publishing papers with high impact factors, keeping up with hot spots, frequently switching research directions, not deeply exploring experimental phenomena, not excavating the scientific essence and connotation, and lacking in depth and systematicness in research are also bad habits that need to be broken urgently. Every year, I spend more energy on revising project applications for some teachers. Most of the applications are novel and innovative, and the key scientific issues are concise and accurate, and the research content and scheme are concrete and feasible. The application is carefully written and can express the research to be carried out in the demonstration with accurate language and strict logic. However, some teachers’ project books are in contrast with the published research papers. The reason is that these teachers only pay attention to the appearance of research, neglect to ask and think about the connotation of their own research, and lack deep insight and understanding of the development trend in this field. Pursuing scientific truth and carrying out innovative research, like teaching and educating people, is a sacred and lofty cause and an important mission of universities. We should cultivate the sense of innovation, adhere to the spirit of seeking truth from facts, adhere to academic integrity, and be a good teacher with taste, character and bottom line.

　　Cctv news(Reporter Brother Chenchen Zhang Qi): Some people say that being a mother is a woman’s second rebirth. However, on the first day of motherhood, all kinds of trivial things seem to detonate the lacrimal gland.

　　In order to achieve full breast milk, the fear of being squeezed into fainting and being lulled into sleep is very difficult every night. It is constantly "escalating", learning and struggling every day, and sometimes getting lost in the contradictory remarks of various parenting experts.

　　"I don’t need the recognition and praise of the whole world. It can only be said that as a mother, I found another self in this world, a tough and strong self. "

　　Whether it’s a working mother or a full-time mother, no one is growing up stumbling.

　　See love in the cracks.

　　"Verapamil hydrochloride tablets", when I first saw this medicine, Wang Lin was looking for a pacifier for her child in a hurry, and turned on the search engine to check it for angina pectoris, variant angina pectoris, unstable angina pectoris and chronic stable angina pectoris.

　　Wang Lin knew that her mother’s heart was not very good, but she never noticed that she had been taking medicine. Usually busy at work, my mother is helping me take care of the children, and my nose is sour, and my memory is coming up.

　　As a professional woman who flies around all the year round, Wang Lin is used to being resolute. When the child was born 100 days ago, due to the cold weather and the illness of the child, he did not take the child to the 100-day banquet. Unexpectedly, he suffered a domestic violence. "My husband questioned why I didn’t take the child and said that I was uneducated." Wang Lin went back on the spot. "There were many people at the scene."

　　After the banquet, the two went home and had another big fight. At that time, Wang Lin’s mother helped take care of the children at home, and when she saw the couple quarreling, she was also blamed together. The quarrel between the two became more and more fierce. When they returned to their bedroom, Wang Lingang pushed the door and was caught by the hair and slapped.

　　The next day, a piece of divorce certificate was in Wang Lin’s hand. At the age of 22, I met and fell in love. After five years of marriage, my feelings collapsed only in an instant. "I won the custody of my children."

　　At this point, Wang Lin officially became a list of pro-working mothers. However, vulnerability does not apply to this single working mother.

　　Wang Lin was delivered by caesarean section. Due to premature rupture of amniotic fluid, uterine contraction was weak after oxytocin was hanged, and she turned to emergency surgery. "Fetal distress and tertiary pollution of amniotic fluid have occurred." The lighting on the operating table clearly mapped the whole operation process. "From the first time the doctor cut the knife to the last time I sewed it, I saw it carefully without fear." The doctor asked her to look at the boy and girl, and she smiled "girl".

　　The 24 hours after operation is the most painful. Because it was the first child, the doctor gave analgesic pump, and if it hurt, he pressed the button, "I forbeared not to press it." The pain went from the back of my hand to the wound on my stomach, and the meat on my abdomen and waist twisted together. "I just want to feed her early."

　　For working mothers, the luckiest thing is to have the support from their families. According to the data of "Investigation Report on the Living Status of Working Mothers in 2019", 73% of working mothers said that their children’s education and upbringing were supported by their parents, and more than 50% of mothers said that their husbands would share the work of caring for their children.

　　After leaving the hospital and going home, Wang Lin took care of the children with her mother, with low back pain, breast-feeding pain and fragmented sleep. She felt that her determination to be a mother would definitely make her strong enough to overcome all difficulties. At that time, Wang Lin’s husband was completely opposite to Wang Lin’s state. "He took care of the children very little. When the children cried, he became restless, because he didn’t want to reduce the quality of sleep. After having children, we slept in separate rooms. To be honest, the time to meet each other every day was very limited, and most of the time he stayed in his room."

　　Despite this, Wang Lin never thought that a TV drama-like plot would happen to herself. After the divorce, my friend said, did you really break up because of such a trivial matter? "In fact, I have found that he rewarded the network anchor several times, but what does this mean?"

　　After experiencing childbirth pain and divorce, Wang Lin still wore high heels and painted delicate makeup as usual, which made her sad and tearful. The child was infected with mycoplasma pneumonia when she was 6 months old. "It’s too small. I have to put a needle in my head, and the child cried. At that moment, I really couldn’t control myself."

　　Later, Wang Lin talked to her mother about her child’s illness. She told her mother that she really knew what it was like to be "distressed". Wang Lin’s mother said that when you cried that night, her mother was also so distressed.

　　At that moment, happiness and falling into life are all details. "If my mother needs a heart in the future, I think I can give it to her."

　　Critical balance point

　　"In Beijing, how much pressure do mothers have to bear in the face of promotion and parenting?" Once, Lin Ling didn’t dare to think much about this problem, but he didn’t expect this situation to really become his daily life so soon.

　　At six o’clock in the morning, Lin Ling got up to prepare the baby’s complementary food: steamed eggs with mixed vegetables, shrimp, nutrition porridge and minced meat. Compared with the initial hurry-scurry, she is much more comfortable now. Kiss the sleeping child. She goes out to work at seven o’clock on time. From Changping to Wangjing, it takes almost two hours to go to work every day by subway and bus. Breast pumps, milk storage bags, ice packs, and small backpacks are stuffed, and the heavy weight always reminds her of the pressure on her shoulders.

　　It is normal to review documents, calculate expenses and prepare statements, and be so busy at work that you forget to eat. But after a little interval, she couldn’t help talking to her family to see what the children were doing, how much they ate and slept soundly, and what stories were staged on this day.

　　For the sake of children, she was transferred from the core department, away from the working mode of staying up all night and being on standby at any time. Now she works at the most efficient pace so that she can get off work on time and go home early to accompany her children. In her view, this rhythm is just a good point, balancing her career pursuit and parenting life.

　　Foreign companies, accountants, working mothers, Lin Ling’s every label is not easy. In the past six years, she has been working, getting married, researching, getting pregnant, having a baby and raising children … …

　　According to the Survey Report on the Living Status of Working Mothers in 2019, working mothers spend an average of 3.17 hours a day in their families, with a career-oriented index of 3.29, which is slightly higher than the overall career confidence index of working women. They have the strongest fighting spirit and devote themselves to their families in their spare time.

　　Four years ago, Lin Ling’s first child, Haohao, was born, and the couple in Beipiao did not have their own house. In order to take advantage of an hour’s lunch break every day to breast-feed Haohao, a family of five rented in an old community near the company, with no decoration, just being close to the unit, which can save time and spend more time with the children. Although parents help to take care of the children, Lin Ling tries his best to grow up with them, and takes them out for a walk no matter how tired they are after work.

　　"Hao Hao has been breast-feeding since he was born. He feeds milk every two hours. I can’t bear to let him cry. I got up in the middle of the night when I heard him cry. After I went to work, Haohao didn’t eat complementary food or drink milk powder. He cried at home and lost weight. Holding a child for a long time, my wrist is sore, and I often have to stick a plaster; The child is thin, sick and dark, and every small change affects my sensitive and nervous nerves. Many times I am exhausted, but I am just a mother, and I can always be resurrected with blood again and again. "

　　Around her, some people choose the workplace without hesitation between their careers and their children, and become real strong women. Some people are workaholics, but they don’t hesitate to naked resignation the second they learn that they are pregnant. In Lin Ling’s eyes, these choices are extreme, and she carefully maintains a balance between work and family, work and child-rearing.

　　Lin Ling said, before you have children, the world belongs to you. Go and do whatever you want. After you have children, you should learn to compromise with yourself. Many times you will be upset and depressed, but you should force yourself to have a good attitude to face the situation. Dreams still have to be there, or to be a person who is useful to society and beneficial to children. "I used to want to travel around Europe, but now I want to see the world together when my children grow up."

　　An undervalued business

　　"If you don’t have children or have never taken care of them for 24 hours, you won’t know the multiple tasks and efficiency of a stay-at-home mother."

　　On the New Year’s Eve of 2016, a group of babies was born. As the sun sets, the afterglow is sprinkled on the baby’s tender little face through the glass window of the delivery room, and the group feels the happiness of being a mother for the first time. "After observing for two hours after delivery, when the baby and I were pushed back to the ward, firecrackers were already heard outside and fireworks were everywhere." The new year began, and the crowds hugged her and thought, "My new life has begun."

　　Because both parents can’t come to help, and the group is not comfortable looking for a child-rearing sister-in-law, they quit their jobs and became full-time mothers. "In the past, I didn’t like children at all, and even had the idea of Dink with my husband. Until I accidentally had my own child, maternal love seemed to be stimulated at once, and the link with the child was particularly close. I didn’t trust people who were not related by blood to bring children."

　　Qunqun majored in art design during her college years, and after graduation, she engaged in her favorite design work. Being a full-time mother really made a great determination for her. "I am more spoiled and grown up, and it is good to take care of myself. The child is just born, and it is a fragile little life. I feel that I have to learn a lot of knowledge so that I can not be anxious when I encounter problems."

　　Cooking is a particularly big burden for the group. "I took her to buy food and cook. For a year or two, she especially liked to hold it. It was not negotiable. I think girls are more sensitive, so they respect and understand her. In this way, I will be involved. When cooking, the baby was afraid of the sound of the range hood and wanted to hold her with one hand and cook with the other. At that time, I felt that I was ‘ One-armed woman ’ You can do it with one hand. "

　　In the summer when the baby was over one year old, groups of people took their children to play on the balcony mat. During that time, "taking the baby during the day and studying scientific parenting at night was a little neurasthenia", and they accidentally stood up and bumped into the corner of the window. "At that time, I felt blood flowing down from the top of my head, like a TV play." After that, she wiped the paper, made a circle of friends, then fed the baby and took a nap. As a result, she fell asleep in a daze until she was awakened by her husband, "I want to take me to the hospital for examination." I went to the hospital wrapped like a "big pineapple", and finally I almost had to sew. "It’s fun to think about it now, and I don’t feel pain."

　　According to the analysis of the Group Analysis Report of Stay-at-home Mothers in 2019, 46% of women miss career opportunities due to childbirth, and children are the career of stay-at-home mothers.

　　The group feels that the mother-infant link is the most precious colostrum, and it is the wing of the mother to take care of the baby angel. "I can perceive her inner thoughts with one look in her eyes, and help her feel her emotions and name them, what is happiness, what is sadness and what is missing … …” Every night before going to bed, the group will take the baby to recall what happened on this day. People they met, things they met, happy and unhappy, will tell their children their opinions.

　　Perhaps it is a long-term interaction, and groups of children have strong memory and expressive ability. She believes that early education does not have to have a high environment and a deep concept. As long as we keep the mother-child link with our children, we can feel each other’s guidance and walk hand in hand mentally. The child’s heart is full, the development is healthy, the relationship is right, and so is the husband and wife.

　　May 8, 2016 is Mother’s Day, and May 9 is Qunqun’s 30th birthday. At 12 o’clock on the 8th, the children fell asleep, and Qunqun brushed their mobile phones. "My husband suddenly asked me to go to the living room and asked me to open the refrigerator door. Just like magic, there was a cake, and I remembered that it was my birthday. I was always so confused, but I felt very happy."

　　Considerable self-growth

　　"On Macey’s first birthday, he suddenly took a few steps off my hand, which made me happy."

　　One small step for the baby and one big step for the mother. The mother looked at Macey as a toddler, sobbing profusely. Not long ago, she was a cute little monster who only ate, drank and slept in her arms. Finally, she took the first step in her life.

　　In 2014, Meng Ma went to a lecture on maternal and child knowledge with an 8-month-old belly. Originally, her teammates vowed to study with her. As a result, from the third time, her teammates kept screaming in bed, so Meng Ma had to go to class alone. "At 12 o’clock that night, I suddenly felt a burst of unusual contractions. When I looked at my watch, it was a regular contraction that hurt for 1 minute every time and hurt every 5 minutes." I rushed to the hospital in a hurry and was born prematurely.

　　At first, the lack of milk has always been a regret for Meng Ma.

　　"I officially gave birth on the third day." After the baby was born, he was hungry for 48 hours. At night, when the nurse made rounds, he would be named, saying that he cried the most on the whole floor. Later, when he was fed probiotics, "as soon as the bitter medicine was put on his mouth, he swished it all in, so hungry that even the medicine was used to satisfy his hunger."

　　There is no way, can’t help pressure from all sides, on the third day, Meng Ma gave Macey milk powder.

　　Touching the soft "granary", Meng Ma felt uncomfortable and made up her mind to chase milk desperately. I heard that the more you squeeze, the more milk you get. Therefore, in the second month, Meng Ma will feed first and then suck it with a breast pump for half an hour every night. "My chest is numb and I don’t feel my own." Once, I squeezed directly until my blood sugar was too low, and I fainted, and I ate and drank sugar water before I recovered. And desperate milking led to breast bruising, but it took a month to get better. Later, after consulting a doctor, I realized that the key to chasing milk is to feed it frequently and for a long time. The baby’s sucking is better than any breast pump.

　　As a result, when Macey cried, I forcibly grabbed him to feed him, and even he was fascinated to feed him regularly: obviously, the baby was still sleeping, and he had to wake him up by bouncing the soles of his feet, rubbing his earlobes, and even rubbing plastic to make a harsh sound, so that he could suck for 20 minutes. "Now, I feel that the baby has been hung on my chest, and even when he falls asleep, he still has nipples — — It directly caused my nipples to crack, bleeding while feeding, and it hurt me to grin and bite my teeth. "

　　Finally, Meng Ma successfully achieved full breast milk.

　　"Looking back now, I think exclusive breast milk is not necessarily the only choice. If it is limited to realistic conditions, you don’t have to feel guilty about adding formula milk to your baby: your identity is not only a mother, but also a wife and an employee … … You need to weigh yourself. "

　　With the birth of Macey, Mengma became a part-time mother. "I helped my former tutor to do research in the middle of the night when the children slept. Later, with the gradual enrichment of parenting experience, I began to become a writer on parenting." Former classmates and colleagues were very surprised when they heard that Mengma chose to be a part-time mother. "Your grades/work are so good, why do you want to be a part-time mother? Isn’t this a waste? "

　　In Meng Ma’s view, it is because I am good at learning that I decided to be a part-time mother, so that I can spend more time and experience learning how to be a qualified parent.

　　"There are no perfect parents in the world, so whenever I learn new knowledge, it is always easy to feel guilty: Ah, what I did before was wrong! I believe everyone will have this idea from time to time, so I want to encourage you in one sentence: what I did was what I knew at that time. When I know more, I do better. "

　　At the end of December 2017, Meng Ma completed the parenting course for 0-5 years old jointly organized by Arizona Children’s Center and the U.S. Department of Education, and learned more reliable parenting content. She also felt a lot about kindergarten education and education software and hardware conditions in the United States.

　　Recognizing vegetables, looking for scarecrows, catching Pieris rapae and scampering along the path … … Even in the city, you can find summer. This is the daily life for Meng Ma to get along with her children. Meng Ma admits that raising children by both husband and wife can avoid the influence of traditional, outdated and backward parenting concepts on children to the maximum extent.

　　"Children’s spilled food will increase the workload of nannies. Most elderly people will shout and rush to help their children up at the first moment when they fall. They will teach their children how to play in their own way, and think that helping children dress, brush their teeth, clean things, etc. should be taken care of by adults."

　　On the first Mother’s Day, Macey took the initiative to kiss Meng Ma, who thought it was the sweetest gift. "These experiences and memories belong to children and to ourselves. They may be anxious to grow up and the future, but when we get old, these precious memories will stay with us for a lifetime, reminding us of the second growth after being parents. " (At the request of the interviewee, the characters in the text are all pseudonyms.)

　　Xiong Zhuowei, a professor of medicine in Peking University, finally died in the First Hospital of Peking University. The attending doctor who rescued her was only a student of Peking University Medical College and was not qualified to practice medicine. What we heard about illegal medical practice in the past is generally in black clinics. How can there be illegal medical practice in a nationally famous third-class first-class (public) hospital like Peking University First Hospital? It’s incredible. Illegal medical practice is by no means a small problem, which is directly related to how to guarantee and protect the people’s right to see a doctor and life. The First Hospital of Peking University is openly breaking the law, which is to make fun of people’s lives. Can the health department at a higher level, which is responsible for supervision, be unaware of the illegal practice of medicine in this hospital? Why didn’t knowing the truth resolutely correct it and develop to such an out-of-control degree?

　　On May 30th, at the invitation of the 19th Academician Conference of China Academy of Sciences, Xie Xiaoliang, a foreign academician of Chinese Academy of Sciences, academician of American Academy of Sciences and named professor of Mallinckrodt in the Department of Chemistry and Chemical Biology of Harvard University, paid an academic visit to the Institute of Biophysics, and wrote the following questions.From Single Molecule Biology to Single Cell GenomicsLecture report of. The report was presided over by Xu Ruiming, director of the Institute of Biophysics.

　　Xie Xiaoliang first introduced the pioneering work of monomolecular enzymology, and explained the characteristics of enzyme’s catalytic function at the monomolecular level. Xie Xiaoliang’s research group used single molecule fluorescence technology to study the expression of protein in bacteria, and analyzed the gene expression in Escherichia coli at the level of single cell. It was found that the expression of protein in a single cell was random. The effect of DNA loops on the transcription process of genes was studied at the single molecule level. It was found that DNA loops would hinder the transcription in space, and when Gyrase gyrase did not exist, the forward supercoiled structure of DNA would slow down the speed of transcription initiation and extension, which eventually led to the inhibition of transcription initiation. Through these studies, Xie Xiaoliang’s research group found that the phenomenon of Transcription Bursting was caused by the shedding and recombination of Gyrase from DNA, and the accumulation and elimination of the forward supercoiled structure of the corresponding DNA.

　　Xie Xiaoliang also introduced Malbac (Multiple Annealing and Looping Based Amplification Cycles) method invented by his research group, and the single cell genome sequencing of human sperm cells completed by this method. Xie Xiaoliang’s research group also improved the accuracy of single-cell genome sequencing detection by META-method; MALBAC-DT (Malbac-Digital Transcriptome) method was developed to detect transcription-related modules (CTM) within the genome, and the detection efficiency was increased by 50%. Using single cell DIP-C technology, the 3D structure of human diploid cell genome was obtained, and the resolution could reach 100nm and 20kb. It was found that two X chromosomes produced different 3D structures due to different activity states. By analyzing the 3D genome structure of olfactory nerve cells, it was found that there were obvious differences between olfactory receptor-related genes and control cells. By studying the 3D genome structure of different cell types at the single cell level, it is found that different cell types have different 3D genome structures.

　　The report is rich in content, clear in logic, vivid in explanation and rich in academic atmosphere. Participants asked questions and interacted with Xie Xiaoliang on issues of interest to them. After the report, Xie Xiaoliang had a discussion with the researchers of the Institute of Biophysics, and conducted in-depth exchanges and discussions on issues of common interest.

　　Xinhua News Agency, Manila, November 12th Communication: He and She in China-ASEAN Destiny Community

　　Xinhua News Agency reporter Zhao Qing Sebrina

　　China and ASEAN are linked by mountains and rivers and are as close as lips and teeth.

　　Over the years, China has adhered to the neighboring diplomatic concept of closeness, sincerity, mutual benefit and tolerance, and has persisted in being good and partner with its neighbors, and has persisted in being good, secure and rich, and constantly promoted regional cooperation.

　　On October 3, 2013, in the meeting hall of Indonesian Parliament, China leaders proposed to build a closer China-ASEAN destiny community, which pointed out the direction for the two sides to jointly build the 21st Century Maritime Silk Road.

　　Relying on the "Belt and Road Initiative", a number of flagship infrastructure projects such as Jakarta-Bandung High-speed Railway and China-Laos Railway have successfully landed in East Asian neighbors, and China enterprises have blossomed in local investment, bringing tangible benefits to people in more and more countries along the route, and their fate is undergoing tremendous changes …

　　"It’s great to have tap water."

　　The Millennium Island takes on a new look.

　　"We used to have electricity for only 4 hours every day, but now we can use electricity for 24 hours; I used to have to go to the rain pool to fetch water, but now I can use clean tap water. It’s really great and convenient. We support this project very much! "

　　Wu Lajue, a villager from Made Island on the west coast of Myanmar, told reporters excitedly while fetching water. The "project" he keeps talking about is the pilot project of the "Belt and Road" construction in Myanmar-the China-Myanmar oil and gas pipeline project.

　　China-Myanmar oil and gas pipeline projects include crude oil pipeline projects and natural gas pipeline projects. The China-Myanmar crude oil pipeline was invested and built by PetroChina and Myanmar Oil and Gas Company, starting from Made Island on the west coast of Myanmar, with a total length of 771 kilometers and a designed annual transportation capacity of 22 million tons. The project was completed on May 30, 2014.

　　On January 30, 2015, the port of Made Island was successfully opened, and large oil tankers successfully docked to unload oil. Made Island became the first stop for transporting crude oil to China. In May this year, the China-Myanmar crude oil pipeline (Myanmar section) was successfully put into operation, marking a new historical stage for the China-Myanmar oil and gas pipeline project.

　　The arrival of the China-Myanmar oil and gas pipeline project has brought about earth-shaking changes in the lives of local people. At one time, Madre Island was a remote island in the Bay of Bengal without roads, fresh water and materials. More than 3,000 islanders made a living by fishing and planting for generations.

　　Today, almost every village here has access to roads, tap water and 24-hour power supply. The island has also built a 3G mobile signal base station, and schools and medical stations are readily available. Some families have purchased agricultural diesel vehicles and motorcycles. Local residents also actively participated in the project construction, with about 1,000 people participating in the project construction. At present, about 50 people are working in the project, 10 of whom are in important technical posts.

　　At present, the port of Made Island is the first modern large-scale international crude oil port in Myanmar and has become an important window for China-Myanmar economic and trade cooperation.

　　"This is the harbor where our happy life sets sail."

　　The change of Hambantota began with the construction of the port.

　　In 2007, with the help of China, Sri Lanka began to build Hambantota Port. Ten years later, Hambantota, a small fishing village in the past, has become the most developed hub town in Sri Lanka: wide asphalt roads, advanced conference centers, sports centers, five-star hotels, Matra airport, and the southern high-speed extension line under construction … After the completion of the second phase of the Hangang project in May next year, Hangang will become a shipping and business center connecting East and West, greatly enhancing Sri Lanka’s international competitiveness and promoting Sri Lanka’s economic development.

　　Many villagers have changed the track of their lives by participating in the construction of the Hangang project. Sydney, a young Sri Lankan, grew up from an intern to a senior engineer here. He not only renovated his home, but also owned his own car.

　　"Driving on the two-way four-lane asphalt road built by China Company every morning, I feel very comfortable looking at the green rice fields passing by the car and the whirling coconut trees bathed in the morning sun." Sydney is amazed at the rapid changes in the city and proud of being able to participate in the construction of the Hangang project.

　　The Hangang project is still under construction, and visitors have been in an endless stream. A local teacher who took students to visit told reporters: "This is not only a port, but also our hope, our future and the harbor where our happy life will set sail!"

　　"Learning Chinese made me a white-collar worker"

　　10 years in a blink of an eye.

　　Starting from the wasteland of Mangyuan, the Sihanoukville Special Economic Zone in Cambodia (referred to as Xigang Special Economic Zone) has developed into the largest special economic zone in Cambodia with the largest number of employed people, and is known as a model for the "Belt and Road" cooperation between China and Cambodia.

　　Xigang Special Zone is jointly developed by Chinese and Cambodian enterprises, with a total planned area of 11.08 square kilometers. Its main industries are textiles and garments, machinery and electronics and high technology. There are complete supporting facilities for production and living here, and more than 100 enterprises from China, Europe, America, Japan and South Korea have provided 16,000 local jobs.

　　In the process of construction and development, Xigang Special Zone insists on the localization of employees, and specially runs training centers to provide local farmers with language and skills training, which also provides them with a broad development world.

　　Chen Xiuli, a Cambodian girl who works as a workshop translator in Creaer Waterleather Cambodia Co., Ltd. in the special zone, is the beneficiary of the training program. Two years ago, Chen Xiuli came to the training center to learn Chinese. She worked hard and has now become a skilled translator. "Learning Chinese made me a white-collar worker. I now earn more than 300 dollars a month, far higher than the 60 dollars of ordinary workers. "

　　At the beginning of this year, Chen Xiuli turned over a new house and bought new furniture and appliances. My parents also retired from the original factory and set up a stall in the special zone to sell sugar cane water, making more money and making life a lot easier. When they mentioned their daughter’s work and present life, their eyes were full of pride and satisfaction.

　　"I have a more accurate goal in my life."

　　Blue sky and white clouds, tree-lined.

　　Next to Highway 331 in Boradang District, Rayong Prefecture, Thailand, near the deep-water port of Lian Chabang, there is Luo Yong Industrial Park in Thailand.

　　Known as the "Industrial Chinatown" in Thailand, more than 90 China enterprises have invested in the park, which has led China to invest more than 2.5 billion US dollars in Thailand, achieving a total industrial value of 8 billion US dollars. After more than ten years of development, the industrial park has become the largest industrial cluster center and manufacturing and export base of China’s traditional industries in Thailand and even ASEAN.

　　The overall planning area of Luo Yong Industrial Park in the middle of Thailand is 12 square kilometers. At present, the development of 1.5 square kilometers in Phase I and 2.5 square kilometers in Phase II has been completed, and the land of 8 square kilometers in Phase III is being developed. After the third phase of development is completed, it is expected to accommodate 300 enterprises and create 100,000 jobs for Thailand. Xu Genluo, president of Luo Yong Industrial Park, told the reporter that China enterprises in the park are trying to integrate into the local area, using Thais as much as possible and providing more than 20,000 jobs for the local area.

　　Cai Youfu, a Thai boy, is a Thai employee of Zhongce Rubber in the industrial park. He graduated from the Chinese Department of Queen Mother University in Chiang Rai, northern Thailand and speaks fluent Chinese. After graduating from college, he entered the rubber work of Zhongce with the advantage of language.

　　"Working with Chinese has taught me a lot, and I am very satisfied with my current job." He told reporters that Luo Yong Industrial Park in Thailand is the organic carrier of the Belt and Road Initiative in Thailand. "Working in China Company, I learned Chinese’s hard-working spirit and gave me a more accurate goal in my life." (Participating in reporters: Zhuang Beining, Tang Lu, Mao Pengfei, Yang Zhou)

　　Since the beginning of this year, the global Internet giants have set off a "hundred-model war", and Microsoft, Google, Baidu and Ali have come to the end one after another. After more than half a year of competition, technology giants are welcoming a new round of road disputes around the big model ecology: facing the parameter "ceiling", will the future of the big model be closed or open?

　　The open source model can run on a home computer.

　　On August 3rd, two open source models, Qwen-7B and Qwen-7B-Chat, were put on the domestic AI developer community "ModelScope", which were Alibaba Cloud Tongyi Qianwen’s 7 billion parameter general model and dialogue model respectively. Both models were open source, free and commercially available.

　　According to reports, Tongyi Qianwen Qwen-7B is a pedestal model that supports many languages such as Chinese and English, and it is trained on more than 2 trillion token (text unit) data sets, while Qwen-7B-Chat is a Chinese-English dialogue model based on the pedestal model, which has reached the cognitive level of human beings.In short, the former is like a "foundation" and the latter is a "house" on the foundation.

　　The actual test shows that the comprehensive performance of Qwen-7B model is good. Among them, on the English proficiency evaluation benchmark MMLU, the score is generally higher than that of the mainstream models with the same parameter scale, even surpassing some models with 12 billion and 13 billion parameter scales. On the Chinese evaluation C-Eval verification set, the model also achieved the highest score of the same scale. Qwen-7B model is also among the best in evaluating GSM8K in mathematical problem solving ability and HumanEval in code ability.

　　That is to say,In the tests of Chinese and English writing, solving mathematical problems and writing codes, Qwen-7B model is properly a "master of learning", and its score even exceeds the international mainstream model with the same parameter level.

　　Besides, the industry is more concerned about the usability of Qwen-7B model. As we all know, the training and operation of mainstream large models need special AI training chips (such as NVIDIA A100), which are not only expensive, but also as high as 10,000 — per NVIDIA A100; 15,000 dollars, and it is monopolized by countries such as Europe and the United States, and it is almost impossible to buy it in China.The domestic Qwen-7B model supports the deployment of consumer graphics cards, which is equivalent to a high-performance home computer to run the model.

　　Thanks to free commercialization and low threshold, the Qwen-7B model has been put on the shelves, which has attracted the attention of AI developers.In just one day, on the code hosting platform GitHub, the Qwen-7B model has been collected by more than a thousand developers, and most of the questioners are Chinese developers.As Alibaba Cloud said in the statement: "Compared with the lively AI open source ecology in the English-speaking world, the Chinese community lacks an excellent pedestal model. The addition of Tongyi Qianwen is expected to provide more choices for the open source community and promote the open source ecological construction of AI in China. "

　　Open source or closed?

　　In fact, Qwen-7B model is not the first big open source model. In fact, GPT-2, the predecessor of ChatGPT, is also completely open source. Its code and framework can be used for free on the Internet, and related papers can be consulted. However, after ChatGPT spread all over the world, OpenAI chose closed-source development, and the model codes such as GPT-3 and GPT-4 have become the trade secrets of OpenAI.

　　The so-called open source is open source code.For example, once the big model is declared open source, anyone can publicly obtain the model source code, modify it or even redevelop it within the scope of copyright restrictions. To make a simple analogy,The source code is like the manuscript of a painting, and everyone can fill in the colors according to the manuscript to create their own artistic paintings.

　　Closed source is just the opposite of open source.Only the source code owner (usually the software developer) has the power to modify the code, others can’t get the "manuscript" and can only buy the finished product from the software developer.

　　The advantages and disadvantages of open source and closed source are very obvious. After open source, the big model will undoubtedly attract more developers, and the application of the big model will be more abundant, but the corresponding supervision and commercialization will become a difficult problem, which is prone to the embarrassing situation of "making wedding clothes for others".After all, open source considers ecological co-prosperity, and it is difficult to figure out the economic account of how much money can be earned at this stage, and these problems happen to be opportunities to close the source.

　　Open source or closed source, this is a big model of life and death, the international giants have given the answer.

　　Meta, the parent company of Facebook, released the big model Llama2 last month, which is open source and free for developers and business partners, while OpenAI firmly chose GPT-4 closed source development, which not only can maintain OpenAI’s leading position in the generative AI industry, but also can earn more revenue. According to the authoritative magazine Fast Company,OpenAI’s revenue in 2023 will reach 200 million US dollars, including providing API data interface services and subscription service fees for chat bots.

　　Domestic big models have gradually begun to "go their separate ways".Alibaba Cloud’s General Meaning ModelAs early as April this year, it was announced to be open to enterprises, and the open source of Qwen-7B model will go further.ERNIE Bot of BaiduIt has also recently announced that it will gradually open the plug-in ecosystem to third-party developers to help developers build their own applications based on the Wenxin model.

　　In contrast, Huawei does not take the usual path. When the Pangu Big Model 3.0 was released, Huawei Cloud publicly stated that,Pangu modelThe full stack technology is independently innovated by Huawei, and no open source technology is adopted. At the same time, Pangu Big Model will gather numerous industry big data (involving industry secrets, etc.), so Pangu Big Model will not be open source in the future.

　　The big parameters are still small and beautiful.

　　In addition, the open source of Qwen-7B model brings another thought:How many parameters do we need a big model?

　　There is no denying that,The parameter scale of the large model is constantly expanding.Take the GPT model under OpenAI as an example. GPT-1 only contains 117 million parameters, and the parameters of GPT-3 have reached 175 billion, which has increased by more than 1000 times in a few years, while the parameters of GPT-4 have exceeded the trillion level.

　　The same is true of large domestic models. Baidu Wenxin model has 260 billion parameters, Tencent mixed-element model has reached 100 billion parameters, Huawei Pangu model has been estimated to be close to GPT-3.5, and ali tong Yida model has officially announced 10 trillion parameters … …According to incomplete statistics, there are at least 79 large-scale models with over 1 billion parameters in China.

　　Unfortunately, the larger the parameter, the stronger the capability of the large model. At the World Artificial Intelligence Conference, Wu Yunsheng, vice president of Tencent Cloud, has a very appropriate metaphor: "Just like athletes practicing physical strength, weightlifters need to lift 200 kilograms of barbells, and swimmers need to lift 100 kilograms. Different types of athletes don’t need everyone to practice 200 kilograms of barbells."

　　As we all know,The higher the parameters of the large model, the more resources and costs are consumed.However, it is not necessary to blindly pursue "large scale" or "high parameters" to deepen the vertical large-scale model of the industry, but to formulate relevant model parameters according to customer needs. For example, the BioGPT-Large model has only 1.5 billion parameters, but its accuracy in biomedical professional tests is better than that of the general model with 100 billion parameters.

　　Sam Altman, co-founder of OpenAI, also publicly stated that OpenAI is approaching the limit of LLM (Large Language Model) scale. The larger the scale, the better the model is, and the parameter scale is no longer an important indicator to measure the quality of the model.

　　Wu Di, the head of intelligent algorithm in Volcano Engine, has a similar view. In the long run, reducing costs will become an important factor in the application of large models. "A well-tuned small and medium-sized model may perform as well as a general large model in a specific job, and the cost may be only one tenth of the original."

　　At present, almost all domestic science and technology manufacturers have got tickets for big models, but the real road choice has just begun.

　　Xinhua News Agency, Beijing, April 18th Question: The key data of the first quarter was released. What do you think of the current economic situation?

　　Xinhua News Agency "Xinhua Viewpoint" reporter

　　In 2023, the first quarterly report of China’s economy was released on the 18th: the gross domestic product (GDP) was 28,499.7 billion yuan, a year-on-year increase of 4.5%.

　　On April 18th, the State Council Press Office held a press conference in Beijing. Fu Linghui, spokesperson of the National Bureau of Statistics and director of the National Economic Statistics Department, introduced the operation of the national economy in the first quarter of 2023 and answered questions from reporters.

　　Facing the severe and complicated international environment and arduous domestic reform, development and stability tasks, China’s economy has made a good start. What do you think of this report card? The "Xinhua Viewpoint" reporter combed the key data.

　　GDP increased by 4.5% year-on-year: the economy stabilized and rebounded.

　　In the first quarter, GDP increased by 4.5% year-on-year, and the growth rate was 1.6 percentage points higher than that in the fourth quarter of last year; The chain increased by 2.2%.

　　"With the rapid and smooth transition of epidemic prevention and control, various policies and measures to stabilize growth, employment and prices have been put forward, positive factors have accumulated and the national economy has stabilized and rebounded." Fu Linghui, spokesman of the National Bureau of Statistics, said.

　　Since the beginning of this year, the World Bank and other international organizations have raised the economic growth forecast of China. "Under the current situation that the overall recovery of the world economy is weak, China’s economy has shown a positive momentum and injected beneficial increments into global growth." World Bank President Malpas said.

　　Fu Linghui said that considering the low base affected by the epidemic in the second quarter of last year, the economic growth rate in the second quarter of this year may be significantly faster than that in the first quarter; With the increase of the base, the growth rate will fall back in the third and fourth quarters. On the whole, however, the endogenous driving force of China’s economic growth is gradually enhanced, and the macro-policies are effective, and the economic operation is expected to improve as a whole.

　　Total consumption exceeds 11 trillion yuan: the overall recovery is improving.

　　In the first quarter, the total retail sales of consumer goods in China was 11,492.2 billion yuan, up 5.8% year-on-year, down 2.7% in the fourth quarter of last year; The contribution rate of final consumption expenditure to economic growth reached 66.6%.

　　With the gradual release of residents’ consumption demand, the growth of upgrading consumption has accelerated, and the consumption of basic life has continued to grow. In the first quarter, the retail sales of goods increased by 4.9% year-on-year, and decreased by 1.7% in the fourth quarter of last year.

　　"The overall consumption has shown a good recovery trend." Fu Linghui said that with the continuous efforts of the consumption promotion policy, the market sales have rebounded significantly, especially the service consumption has improved significantly, and the consumption has significantly enhanced the economic growth.

　　Yang Guangpu, an associate researcher at the State Council Development Research Center, said that at present, efforts should still be made to enhance residents’ confidence and ability in consumption, do everything possible to increase residents’ income, so that people can spend more confidently, and actively increase quality supply, effectively combine consumption expansion with supply-side structural reform, and continuously release consumption potential.

　　Fixed assets investment increased by 5.1% year-on-year: the steady growth of investment is expected to continue.

　　In the first quarter, the national investment in fixed assets increased by 5.1% year-on-year, which was the same as that of the previous year.

　　Fu Linghui said that since the beginning of this year, China has insisted on expanding domestic demand, actively played the key role of investment in optimizing the supply structure, increased investment in key areas and key links, and expanded investment in people’s livelihood, effectively safeguarding and improving people’s lives. The steady growth of investment has effectively enhanced the development potential.

　　It is worth noting that investment in high-tech industries grew rapidly in the first quarter, with a year-on-year increase of 16%. "The rapid development of high-tech industries is conducive to further enhancing the resilience of China’s industrial chain supply chain, and is conducive to continuously improving China’s industrial added value and its strength in global industrial competition." Xu Zhaoyuan, deputy director of the Industrial Economics Research Department of the State Council Development Research Center, said.

　　Yang Guangpu said that with the sustained economic recovery, the technological transformation, transformation and upgrading of traditional industries are expected to accelerate, digital transformation and green and low-carbon transformation continue to advance, and with the implementation of various support policies, investment is expected to maintain steady growth.

　　Foreign trade increased by 4.8% year-on-year: export growth was higher than expected.

　　In the first quarter, the total import and export value of China’s goods trade was 9.89 trillion yuan, a year-on-year increase of 4.8%. In March, the total import and export value was 3.71 trillion yuan, up 15.5% year-on-year, of which exports increased by 23.4% year-on-year and imports increased by 6.1%.

　　Lu Daliang, director of the Statistics and Analysis Department of the General Administration of Customs, said that since the beginning of this year, China’s economic operation has stabilized and rebounded, production and demand have gradually improved, and foreign trade imports and exports have stabilized significantly. "In the first quarter, China’s foreign trade import and export showed strong resilience, and the start was stable and good, laying the foundation for achieving stable and improved foreign trade throughout the year."

　　Zhuang Rui, a professor at university of international business and economics, said that the rapid export growth is mainly reflected in the bright export of electromechanical and high-tech products represented by new energy vehicles, as well as the improvement of export growth to countries along the Belt and Road Initiative and countries with regional comprehensive economic partnership agreements (RCEP) and other trading partners. In addition, due to the narrowing of the year-on-year increase in international commodity prices, the growth rate of imports is relatively low.

　　CPI rose by 1.3% year-on-year: prices remained stable.

　　In the first quarter, the national consumer price index (CPI) rose by 1.3% year-on-year, maintaining a moderate increase, and domestic prices continued to run smoothly.

　　Stabilizing prices is an important task for doing a good job in economic work this year. Fu Linghui said that the CPI increase continued to fall, mainly affected by some stage factors: after the Spring Festival, the market demand fell, the weather turned warmer, the listing of fresh vegetables increased more, and the prices of some foods fell; The supply of live pigs is sufficient and the price of pork has declined; The international energy market, especially the crude oil market, has generally declined, which has led to lower domestic energy prices and so on.

　　Although the increase of CPI has declined, the market supply and demand have remained basically stable. In the first quarter, the core CPI excluding food and energy prices rose by 0.8% year-on-year, which was the same as that in January and February.

　　"Looking forward to the whole year, China’s industrial and agricultural products and services are well supplied, production and marketing are smoothly connected, the market order is good, and the overall economic recovery trend will gradually appear in prices. It is expected that the overall price level will generally operate in a reasonable range." Guo Liyan, director of the Comprehensive Situation Research Office of China Macroeconomic Research Institute, said.

　　PPI decreased by 1.6% year-on-year: it is expected to gradually return to a reasonable level.

　　In the first quarter, the national producer price index (PPI) decreased by 1.6% year-on-year, of which the price of means of production decreased by 2.3%.

　　Fu Linghui said that since the beginning of this year, world economic growth has slowed down, market demand has weakened, supply bottlenecks have eased, and commodity prices have fallen, which has driven down the prices of domestic oil, nonferrous metals and other related industries. In addition, the high base in the same period last year has led to a decline in PPI. Expanded.

　　Judging from the ring comparison, the PPI is basically stable. In January, PPI decreased by 0.4% month-on-month, while in February and March, it was flat.

　　Fu Linghui said that from the next stage, domestic demand generally tends to pick up, which has a certain pull-up effect on PPI, but the import transmission of international commodity prices still exists, and with the high base in the same period last year, PPI may be in a downward range in the short term. However, with the recovery of domestic economy, cardinal utility will gradually decline, and PPI will gradually return to a reasonable level.

　　The national industrial added value increased by 3% year-on-year: achieving steady growth.

　　In the first quarter, the added value of industrial enterprises above designated size increased by 3% year-on-year, and the growth rate was 0.3 percentage points faster than that in the fourth quarter of last year.

　　From the perspective of industry, among the 41 major industries in the first quarter, 23 industries maintained growth year-on-year, with a growth rate of over 50%. Compared with the fourth quarter of last year, the growth rate of added value of 20 industries rebounded.

　　Production of small and micro enterprises has improved. In the first quarter, the added value of small and micro enterprises above designated size increased by 3.1% year on year. According to the questionnaire survey, the prosperity index of small and micro-industrial enterprises under the regulations increased by 1.7 percentage points over the fourth quarter of last year, and the proportion of enterprises with good production and operation conditions increased by 1.2 percentage points.

　　"In the first quarter, the steady growth policy continued to be effective, the market demand picked up, the supply chain of the industrial chain accelerated to recover, and industrial production showed positive changes, but there was uncertainty in the growth of external demand, and the prices of industrial products were still falling." Fu Linghui said that in the next stage, it is necessary to deepen the structural reform of the supply side, vigorously transform and upgrade traditional industries, cultivate and expand emerging industries, and promote the healthy development of industries.

　　The average unemployment rate in national urban surveys is 5.5%: the employment situation has improved.

　　In the first quarter, the national urban survey unemployment rate averaged 5.5%, down 0.1 percentage point from the fourth quarter of last year. Among them, the urban survey unemployment rate in March was 5.3%, down 0.3 percentage points from February.

　　In March, the unemployment rate of the labor force aged 25 to 59 was 4.3%, down 0.5 percentage points from the previous month; The unemployment rate of migrant agricultural registered labor decreased by 0.7 percentage points from last month … … The unemployment rate of the main employment groups has dropped significantly, and the employment of migrant workers has accelerated.

　　Stabilizing business entities is the key to stabilizing employment. The Ministry of Human Resources and Social Security and other three departments have issued a notice at the end of March, which will continue to implement the policy of reducing unemployment and industrial injury insurance rates until the end of 2024. It is estimated that the average annual burden reduction this year and next will be about 180 billion yuan, and all kinds of business entities including small and medium-sized enterprises will generally benefit.

　　Fu Linghui said that with the economic recovery and the expansion of employment demand, the employment situation is expected to continue to improve. However, in view of the structural contradiction of employment, we should continue to increase employment assistance for young people, especially college graduates, accelerate the pace of industrial upgrading, and provide more high-quality jobs.
