19101012. Hua was born in Jintan County, Jiangsu Province. His family is poor and he is determined to study hard. When he was in middle school, in a math class, the teacher gave the students a famous question: "Today, things are unknown, and the number of three is two." When everyone was thinking, Hua stood up and said, "23." His answer surprised the teacher and was praised by him. From then on, he fell in love with mathematics.

After finishing the first grade of junior high school, Hua dropped out of school because of his poor family, so he had to stand in front of the counter for his parents, but he still insisted on teaching himself mathematics. Through his unremitting efforts, his paper "Why the Fifth Equation of Su Jiaju's Algebra can't be solved" was discovered by Professor Xiong Qinglai, head of the Department of Mathematics of Tsinghua University, and invited him to Tsinghua University. Hua was hired as a university teacher, which is unprecedented in the history of Tsinghua University.

1936 In the summer, Hua, who was already an outstanding mathematician, spent two years as a visiting scholar at Cambridge University in England. At this time, the news of the Anti-Japanese War spread all over Britain, and he returned to the motherland with strong patriotic enthusiasm and gave lectures in The National SouthWest Associated University.

China attaches great importance to the direct application of mathematical methods in industrial and agricultural production. He often goes deep into factory guidance, popularizes the application of mathematics and writes popular science books.

Hua has also set a shining example for young people to become self-taught. He is a self-taught mathematician without a college degree. He said, "I am not afraid of difficulties and study hard. This is my main experience in learning mathematics well." "The so-called genius is to rely on unremitting efforts."

Hua is also a math educator. It has trained a large number of outstanding mathematicians such as Wang Yuan, Chen Jingrun, Lu Qikeng, Yang Le and Zhang Guanghou. In order to cultivate the younger generation, he has compiled some extracurricular reading materials for middle school students.
