What is China's attitude towards learning mathematics?
Hua has been smart and studious since childhood. In junior high school, he showed a special talent in math class. One day, Mr. Wang Weike gave the class a math problem, which was a topic in Sun Tzu's Art of War: "There are unknowns at present, three counts leave two, five counts leave three, and seven counts leave two." What is the geometry of things? " When Mr. Wang was reading this question, he read slowly and his voice was cadenced. After reading the topic, Mr. Wang swept his eyes to the whole class, and his eyes were full of nervous and confused faces. Suddenly, a student stood up and said, "There are 23 items." This is a familiar voice that awakens students from thinking and doubts. Everyone looked at him with amazing eyes. The first student to tell the answer is young Hua. When solving this problem, Hua thinks like this: starting from "the number of seven plus seven gets two", that is, seven gets two, then the multiple of seven plus two is this number, so it is not necessary to assume that this number is 7 × 3+2 = 23. Divide 23:23 by 3, leaving 2; 23 is divided by 5, so 23 meets the requirements of the topic. It is precisely because Hua was diligent and eager to learn since he was a child that Teacher Wang Weike paid more attention to his intelligence. Mr. Wang was deeply impressed by Hua when he was at school.

At the age of 0/8, Mr. Wang Weike became the principal of Jintan County Middle School. President Wang cherishes talents and invites Hua to be an accountant and do daily work at school. Since then, Hua has become busier. Recalling the experience during this period, he said, "In addition to the heavy affairs at school, I have to help my mother manage the affairs of the small shop sooner or later. I can't go home until around 8 o'clock every night. After cleaning up the account of the small shop, you can go to learn math, often late at night. " In other words, even after busy business, Hua never forgot to study mathematics, so his mathematics level is constantly improving.

When Hua 19 years old, by chance, he borrowed a magazine named "Learning Arts" and published the article "The Solution of Algebraic quintic Equation" written by Professor Su Jiaju in the seventh volume of this magazine, which aroused China's strong interest. After reading and thinking, Hua found that there were fundamental mistakes in the article. So he asked President Wang, "Can you write an article criticizing the mistakes in Professor Su's article?" Hua's question was positively answered by President Wang: "Of course, saints are also wrong, so what can't be criticized!" Dean Wang is the translator of Italian poet Dante's masterpiece Divine Comedy. His words gave China great encouragement. Therefore, Hua wrote an article with strict logic and sufficient argumentation, which was reviewed and revised by Dean Wang and sent to Shanghai Science magazine. The article was published in 1930. As soon as the article was published, it attracted the attention of many people at that time. At that time, Professor Xiong Qinglai, head of the Department of Mathematics at Tsinghua University, saw this article. Moreover, I was even more shocked to learn that the author of this article was a junior high school boy in Jintan County with only a junior high school diploma. Seeing Hua's talent, he immediately wrote to Jintan Middle School and invited Hua to work in Tsinghua University. After receiving the letter, Hua thought twice: on the one hand, he remembered that before this, President Wang had asked him to teach a cram school in Jintan county junior high school, and because someone complained that President Wang had appointed an unqualified teacher (how could a junior high school graduate be qualified to teach junior high school), President Wang had to resign as president, and he no longer taught; On the other hand, because of his poor family, he even had difficulty traveling to Beijing, so he wrote back and politely declined Professor Xiong's invitation. After Professor Xiong received Hua's reply, the thirsty Bole wrote to urge him. The letter said: If you don't come, I will visit you in Jintan myself. Hua once again received a letter from Professor Xiong, from which he learned the sincerity and sincerity of his invitation. He felt that he had really failed Professor Xiong's kindness, so he had to borrow money from his father and was invited to Tsinghua. In Tsinghua University, Hua became a teaching assistant. The main responsibilities are to manage books in the Department of Mathematics, send and receive official documents, collect stationery and draw charts. So that he can use his spare time to read books and listen to lectures. Under the arrangement and guidance of Professor Xiong, Hua made rapid progress in his studies, studied hard and often taught himself late into the night. It took him only one and a half years to complete the college course and four months to teach himself English, which can reach the level of reading English mathematics literature. In addition, he also taught himself German, especially after listening to the postgraduate courses, his mathematics literacy has been greatly improved and he has made new achievements. His three papers were published in foreign mathematical magazines, and Tsinghua University's teachers had to sit up and take notice of him. Soon, at a meeting of professors in Tsinghua University, it was decided to let him go to Tsinghua as a teacher with only junior high school education. It can be seen that Hua's success is mainly due to his own efforts. When talking with middle school students about learning mathematics, Hua said, "I am not afraid of difficulties, and studying hard is my main experience in learning mathematics well." He also said: "I don't despise easy questions. If I practice easy today, I will easily encounter difficulties tomorrow. I am not afraid of difficult problems, and I am always ready to solve them when necessary. I believe that as long as we work hard, there will be no insurmountable difficulties and no impregnable fortress. " This is how Hua studied hard before he became a university teacher from a young man with only junior high school education. 1936, Professor Xiong Qinglai recommended Hua to study at Cambridge University in England. 1938, Hua returned to the disaster-stricken motherland under the Japanese army's iron hoof, and was recommended by Professor Xiong Qinglai as Professor The National SouthWest Associated University at the age of 28. During his stay in The National SouthWest Associated University, Hua lived a very hard life. Their family lives in two small rooms in a small village on the outskirts of Kunming. There are pigsty and cowshed under the room, and the sanitary environment can be imagined. When recalling this life, Hua said, "A wait is like a bean overnight. The so-called lamp is just a broken cigarette can. Put an oil lamp and pick some broken cotton as a wick. To save vegetable oil, twist the core slightly. At night, the cow itches and shakes, and the dangerous building will fall down! " Although Hua lives in such a building and leads a hard life, he keeps working hard. It took him three years to write a mathematical manuscript called "The Theory of Stacked Prime Numbers". After Hua finished writing "The Theory of Heap Prime Numbers", he naturally planned to publish a book. So he translated the Chinese manuscript into English and sent it to the then "Academia Sinica". However, Academia Sinica not only failed to publish it, but also lost the manuscript. This is a great blow to China. Three years' efforts were in vain. Why not make him feel bad? Later, Hua sent an English version of The Theory of Iterated Prime Numbers to the then Soviet academician Victor Fu, and the English version was finally translated into Russian by the Soviet Union and published. After the publication of this book, it caused a shock in mathematics. After the founding of New China, The Theory of Overlapping Primes (Russian version) was translated into Chinese and published in China. For example, the theory of prime numbers on overlapping bases was first published in other countries and then in China, which is also a rare phenomenon in the world publishing history.

Hua went to school for nine years with only a junior high school diploma, but he became an outstanding mathematician with a good reputation at home and abroad. Hua's life is a life of hard struggle and a model of self-study. His motto "genius lies in accumulation, cleverness lies in diligence" reveals the secret of this success. His motto "Old trees are easy to be empty, old people are easy to be loose, the way of science, keeping empty and keeping loose" is worth remembering by future generations. The last wish of the giant who initiated modern mathematics research in China was "I really hope that the corpse can be useful to the revolution. Once the wall can be used as a ladder, crossing the ditch can be used as a bridge. "
