Hua has been struggling in the national disaster all his life. He often says that he has experienced three disasters in his life. Poor from a small family, out of school, seriously ill, and disabled in both legs. During the second disaster in War of Resistance against Japanese Aggression, it was isolated from the world and lacked reference books. The third disaster was the "Cultural Revolution". His home was searched, his hand was lost, he was forbidden to go to the library, and his assistants and students were assigned to other places. In such a harsh environment, you can imagine how much effort you have to make and how much you have achieved.

As early as 1940s, Hua was one of the leading mathematicians in the field of number theory. But he is not satisfied, he will not stop, he would rather start a new stove, leave number theory and learn algebra and complex analysis that he is not familiar with. How much perseverance and courage are needed!

Hua is good at telling profound truth in vivid language. These words are concise, philosophical and unforgettable. As early as the SO era, he proposed that "genius lies in accumulation, and cleverness lies in diligence". Although Hua is brilliant, he never mentions his own talent. Instead, he regards "diligence" and "accumulation", which are much more important than cleverness, as the key to success, and repeatedly educates young people to learn mathematics so that they can exercise themselves all the time. In the mid-1950s, in response to the problem that some young people in the Institute of Mathematics were complacent after making some achievements, or kept writing papers at the same level, Hua put forward in time: "There must be speed and acceleration." The so-called "speed" means producing results, and the so-called "acceleration" means constantly improving the quality of results. Just after the "Cultural Revolution", some people, especially young people, were influenced by bad social atmosphere, and some departments were eager for success, frequently demanding grades, evaluating bonuses and other practices that were not in line with scientific laws, which led to the corruption of the style of study. Performance for shoddy, fame and fortune, wanton boasting. 1978, he earnestly put forward at the Chengdu conference in chinese mathematical society: "Early publication, late evaluation." Later, it was further put forward: "Efforts are in me, and evaluation is in people." This actually puts forward the objective law of scientific development and scientific work evaluation, that is, scientific work can gradually determine its true value after historical test, which is an objective law that is independent of human subjective will. "

Hua never hides his weaknesses. As long as he can learn, he would rather expose them. When he visited Britain at the age of seventy, he changed the idiom "Don't teach others an axe" to "teach others an axe" to encourage himself. In fact, the previous sentence is that people should hide their shortcomings and not expose them. Did Hua go to college to help others with their expertise, or did he turn lectures into formalism because he didn't specialize in others? Hua chose the former, that is, "wait a minute, and you will arrive at the door." As early as the 1950s, Hua compared mathematics to playing chess in the preface of Introduction to Number Theory, calling on everyone to find a master, that is, to compete with great mathematicians. There is a rule in chess in China, that is, "A gentleman does not regret watching chess without saying a word". 198 1 year, in a speech in Huainan coal mine, Hua pointed out: "Watching chess is not a gentleman, help each other; I regret the gentleman and change my shortcomings. " It means that if you see someone else's work problems, you must speak up. On the other hand, when you find something wrong with yourself, you must correct it. These are "gentlemen" and "husbands". In view of the fact that some people retreat when they encounter difficulties and lack the spirit of sticking to the end, Hua wrote on a banner for Jintan Middle School: "People cannot say that the Yellow River will not die, but I say that the Yellow River will be stronger."

When people get old, their energy will decline, which is a natural law. Hua knows that time waits for no man. 1979 when he was in England, he pointed out: "The village is old and easy to empty, and people are old and easy to disperse. The scientific approach is to abstain from empty and scattered. I am willing to stick to it all my life. " This can also be said to be his "determination book" to fight against his aging with the greatest determination, so as to spur himself. The patient with the second myocardial infarction in Hualuosuo still insisted on working in the hospital. He pointed out: "My philosophy is not to prolong life as much as possible, but to do more work during the day." If you are ill, you should listen to the doctor and have a good rest. But his indomitable spirit is still valuable.

In a word, all of Hua's expositions are permeated with a general spirit, that is, constant struggle and continuous progress.

Hua is a modern mathematician in China. 1910165438 was born in Jintan county, Jiangsu province, and 1985 died in Tokyo, Japan in June. 1924 After graduating from junior high school, I studied in Shanghai China Vocational School for less than one year. I dropped out of school because of family poverty and studied mathematics hard. 1930, he published an article on solving algebraic equations in Science, which attracted Xiong Qinglai's attention and was invited to work in Tsinghua University. Under the guidance of Yang Wuzhi, he began to study number theory. 65438-0934, became a researcher of China Education and Culture Foundation. 1936 went to Cambridge University as a visiting scholar. 1938 returned to China and was employed by Professor The National SouthWest Associated University.

From 65438 to 0946, he visited the Soviet Union for three months at the invitation of the Soviet Academy of Sciences. In the same year, at the invitation of Princeton Institute for Advanced Studies, he served as a researcher and taught at Princeton University. From 65438 to 0948, he was a professor at the University of Illinois. After returning to China from 65438 to 0950, he successively served as Professor Tsinghua University, director of the Institute of Mathematics of China Academy of Sciences, member and deputy director of the Department of Mathematics, director and vice president of the Department of Mathematics of University of Science and Technology of China, director of the Institute of Applied Mathematics of China Academy of Sciences, vice president of China Academy of Sciences and member of the presidium. He also served as chairman of chinese mathematical society for many times. In addition, Hua served as the first, second, third, fourth and fifth members of the Standing Committee and vice chairman of the Sixth National Committee of the China People's Political Consultative Conference.

Hua is a world-renowned mathematician. In the Smithsonian Museum, Chicago Museum of Science and Technology and other famous museums, his name is tied with a few classic mathematicians. Elected as a foreign academician of the American Academy of Sciences, a member of the Third World Academy of Sciences and a member of the Bavarian Academy of Sciences of the Federal Republic of Germany. He was awarded an honorary doctorate by Nancy University in France, the Chinese University of Hong Kong and the University of Illinois in the United States.

Hua has made outstanding contributions in a wide range of mathematical fields, such as analytic number theory, matrix geometry, typical groups, automorphic function theory, multiple complex variable function theory, partial differential equations, high-dimensional numerical integration and so on.

Because of Hua's great contribution, many theorems, lemmas, inequalities, operators and methods are named after him. Published nearly 300 monographs and academic papers.

China also advocates the development of applied mathematics and computers according to the reality of China and the international trend. He personally went to 27 provinces and cities to promote the application of mathematical methods for 20 years and made great contributions to economic construction.
