1902 was born in a mountain village in Pingyang county, Zhejiang province in September. Although his family is poor, his parents still scrimp and save for his school. When he was in junior high school, he was not interested in mathematics and thought it was too simple to learn. However, a later math class influenced his life.

When Su was in the third grade, she was studying in the No.60 Middle School in Zhejiang Province. A teacher, Yang, who had just returned from studying in Tokyo, taught math. In the first class, Teacher Yang told a story instead of math. He said, "In today's world, the law of the jungle, the world powers rely on ships to build their guns, and all want to eat China and carve it up. The danger of national extinction in China is imminent. It is a stroke. " Every student here is responsible. He quoted a large number of mathematics in the development of modern science and technology. The last sentence of this class is: "In order to save the country and survive, we must revitalize science. Mathematics is the pioneer of science. In order to develop science, we must learn math well. " Sue has attended many classes in her life, but this one will never be forgotten.
