In 1978, Peking University resumed the graduate admissions examination, and many candidates went all out to face the exam, including 38-year-old Zhang Zhusheng, and other candidates were engrossed in solving the questions, only Zhang Zhusheng found that one of the questions was not solved, he wrote detailed ideas to prove that the question was wrong, and only he scored on this question after the score was announced, and he took the first place to enter the graduate school of the Department of Mathematics of Peking University.

Zhang Zhusheng, as a genius in mathematics, has been cultivating talents in the field of mathematics all his life, even if he was tortured by illness, he still led students to win the first place in the International Mathematics Olympiad for five consecutive years.

Zhang Zhusheng

Zhang Zhusheng dedicated his life to education, why can't he be rated as a professional title? What exactly did he go through? Let's walk into Zhang Zhusheng's poor but admirable life together.

1. Don't bow to fate and show great talent

Zhang Zhusheng was born in Guiyang in 1940, his family was poor, his health was not good since he was a child, he got polio due to fever at the age of two, although he was treated in time, the cerebellum was still irreversibly damaged, life was unsatisfactory but he would not bow to fate, showing a thirst for knowledge.

Zhang Zhusheng was able to independently study various small inventions when he was in the 5th grade, and won a lot of awards, Zhang Zhusheng is the pride of his family, but bad luck is looking for a miserable person, Zhang Zhusheng broke his left hand at the age of 13, but because his family was poor, there was no money to treat him, resulting in a permanent disability of his left hand, and he could no longer engage in invention and creation.

Although his left arm is disabled, he is not depressed, but to spend more time on studying, he loves mathematics very much, and shows a strong talent in the field of mathematics, at the age of 19, Zhang Zhusheng was admitted to the Department of Mathematics of Sichuan University, and then carried out decades of professional mathematical research.

Zhang Zhusheng's outstanding mathematical talent is amazing, in his sophomore year he passed the fifth year of the course, and achieved the highest score, teachers say that he is a rare mathematical genius, Zhang Zhusheng with his unique mathematical attainments, get the opportunity to stay in school to teach, he silently dedicated 14 years on the three-foot podium.

Zhang Zhusheng can always explain the complex knowledge in an easy-to-understand way, the esoteric mathematical theory can be understood by the students through his explanation, many times he talks too selfless and often forgets the time, and even once spoke for three hours, his class is very popular with the students, everyone will always can't help but show respect when it comes to Zhang Zhusheng.

Even as a teacher, Zhang Zhusheng still adheres to the concept of "living to learn from the old", he continues to research and explore in the field of differential dynamics, hoping that the mainland will have more breakthroughs in this area, Zhang Zhusheng is an excellent teacher in the hearts of colleagues and students, he has been teaching at Sichuan University for 14 years, but he can't even evaluate the title, at most he can only be regarded as a lecturer.

Sichuan University

Zhang Zhusheng asked the reason for the failure to evaluate the title inquiry, and the school only replied that he was unqualified, obviously this reason could not convince Zhang Zhusheng, because there were many people who were not as capable as him, and the school finally did not give him a reasonable explanation, although Zhang Zhusheng felt that it was very unfair to himself, but he was not interested in this, his lifelong wish was to do scientific research well, and then he resigned and planned to prepare for the graduate school of the Department of Mathematics of Peking University.

May 1978 is the first time in 10 years that Peking University resumed the postgraduate examination, the age span of the candidates is quite large, everyone attaches great importance to this examination, some people are nervous and some people are calm, everyone is concentrating on answering the questions, for fear that accidentally doing the wrong question will affect the results, everyone is taking the exam seriously, Zhang Zhusheng suddenly raised his hand to signal the teacher, he found that the last question on the test paper was wrong.

Zhang Zhusheng quickly finished writing the previous questions, and the last question was unsolvable no matter how he calculated it, so he asked the teacher if there was a mistake in this question, but he didn't expect the teacher to sarcastically mock Zhang Zhusheng: "I can't calculate the answer myself, or find the reason from myself, these questions are taught by the Department of Mathematics, how can there be mistakes." ”

Zhang Zhusheng didn't say anything more, he wrote "There is no solution to this question" under the question, and then wrote his own solution ideas, proving that this question was indeed wrong, and other candidates heard about Zhang Zhusheng's approach, everyone felt that he was too confident, but when the results were announced, everyone knew that what Zhang Zhusheng said was true.

It turned out that the last question was really unsolvable, only Zhang Zhusheng alone got 10 points on this question, he was admitted to the graduate school of the Department of Mathematics of Peking University with the first place, he studied under the famous mathematician Liao Shantao, and even the teacher said that it was more than enough to give lectures to graduate students at his level, which shows that his strength and talent should not be underestimated.

Second, he has worked tirelessly for education, and he is still working tirelessly when he is terminally ill

In 1982, Zhang Zhusheng broke through one of the four conjectures of the famous mathematician Smale in his graduate thesis, this international mathematical problem plagued many mathematicians, but Zhang Zhusheng found a solution in a short period of time, which is enough to see his strength and wisdom.

In July 1983, the president invited more than 100 experts and scholars to hold a doctoral dissertation defense for Zhang Zhusheng in a classroom of Peking University, which attracted wide attention, Zhang Zhusheng once again showed super strength and academic achievements at the defense meeting, and his talent was finally recognized by everyone, which also made him the No. 001 doctor since the establishment of Peking University, and his graduation thesis was wonderful and was still exhibited in Peking University.

Zhang Zhusheng became the first doctor of Peking University to be published in the newspaper

Zhang Zhusheng is talented but extremely simple, his classmates say that Zhang Zhusheng's knowledge, eloquence, and enthusiasm for academics will make others forget his physical disability, he is the main lecturer in the class, can write the entire blackboard, write and erase, wipe and write, and the clothes are all chalk dust after a class.

Zhang Zhusheng came back from a visit to United States in 1986, the leader gave him a difficult task, other teachers did not want to write textbooks, only Zhang Zhusheng was willing to meet the challenge, at this time he was in the golden age of scientific research, the preparation of textbooks is not considered research results, but also spend a lot of time and energy, scientific research workers are more willing to engage in research, so everyone does not want to do thankless things.

When Zhang Zhusheng was teaching at Sichuan University, he felt that the teaching materials should be reformed, and now that there is such an opportunity, he can just get his wish, Zhang Zhusheng thinks that if everyone chooses to work with their personal likes and dislikes, how to innovate education, and what others are not willing to do, he is willing to do.

"New Lectures on Mathematical Analysis" written by Zhang Zhusheng

In addition to attending classes, Zhang Zhusheng studied and compiled textbooks, and spent five years successfully compiling three volumes of "New Lectures on Mathematical Analysis", which made great contributions to mathematics education, and many colleges and universities have taken Zhang Zhusheng's books as an important teaching tool.

Soon after Zhang Zhusheng finished compiling the textbook, he was found to have nasopharyngeal cancer, and began a 12-year road to fight cancer, his condition became more and more serious, and the school persuaded him to be hospitalized, but Zhang Zhusheng still insisted on taking sick to class, she regarded the lecture as more important than life, if he was not allowed to attend class, it would be his life, and the doctor also advised him to go home to rest, but Zhang Zhusheng always said: "You let me be hospitalized is to let me die." ”

Zhang Zhusheng's cancer cells have spread to the whole body, in 1995 he received another new task, he was appointed as the head coach of the national team of the Olympiad competition, responsible for taking middle school students to participate in international competitions, Zhang Zhusheng's wife Liu Lingling heard about this, asked him to explain the situation to the leader, resigned from this job, because his body can no longer bear any fatigue.

Zhang Zhusheng has to undergo dialysis every week, and the workload of leading the team to participate in the competition is very large, in addition to him, he also has to take care of teaching, his body can't bear it at all, his wife's worries are very clear, but this work is of great significance, he insists on leading the team to compete, his wife really can't move him, can only tell him to feel tired and must rest, but once he puts himself into work, Zhang Zhusheng can't take care of it so much.

Zhang Zhusheng devoted himself to studying the topic and improving the thinking ability of the students, and the cancer cells spread more seriously in just a few months, but he asked the doctor not to tell his wife about it, in addition to class, he also had to find a way to teach advanced mathematics to middle school students in an easy-to-understand way, and also to maintain the innovation of the problem.

Zhang Zhusheng's workload has greatly increased compared to before, he has no complaints, he hopes to lead students to create good results with his own efforts, he led the Chinese team from Canada to Argentina, fought internationally for five years, stood out from more than 70 countries, won the first place in the world Olympiad team total score for five consecutive times, of which 3 times all team members won the gold medal together, he let the world see the strength of Chinese mathematics.

During the competition, Zhang Zhusheng did not relax for a moment, the team's good results were the result of everyone's joint efforts, but it was also his health in exchange, the cancer cells had spread to the liver, and he faced great pain in the last 5 years of his life.

Liver cancer caused Zhang Zhusheng to be swollen from the waist down, because of colitis, he had to go to the bathroom dozens of times a day, he was worried that he would go to the bathroom during class, he would fast food and water a day in advance, even if he was terminally ill, he was still optimistic that everything would be fine.

3. If you fail to evaluate your job title in your life, your great personality will always be missed

Since September 2001, Zhang Zhusheng has not even been able to walk, he feels very laborious to go 500 meters from home to school, every day his wife will call the taxi downstairs, and when he arrives at school, his wife will help him into the classroom, and on the afternoon of January 11, 2002, it was the last time Zhang Zhusheng entered the classroom, and he insisted on invigilating the students.

Zhang Zhusheng was carried into the examination room by several graduate students, the whole exam lasted for 3 hours, he sat motionless in the examination room, this is his habit for so many years, never go to the bathroom during the invigilation, Zhang Zhusheng was admitted to the hospital after the exam, his illness has been medicine stone without a doctor, the doctor told his wife, the only thing he can do now is to accompany him well, Zhang Zhusheng has no children and no daughters in his life, he has always said that he has devoted his life to education without regrets.

The picture comes from the Internet

On February 6, 2002, Zhang Zhusheng passed away, and the campus discussion of Peking University was full of everyone's thoughts about him, whether it was students or teachers, Zhang Zhusheng was most evaluated for poverty and simplicity, he had given free training to middle school teachers in Haidian District, Beijing for 8 years, but his home did not even have a decent piece of furniture.

Although Zhang Zhusheng has a glorious past, but he has not been rated as a professional title throughout his life, in fact, he has long looked down on this matter, spiritual wealth is far more pleasant to him than material, what he really wants to do is to cultivate talents, solve more mathematical problems, do these have a clear conscience, Zhang Zhusheng's life is worth remembering, his spirit should be inherited.
