China's Qiu Chengtong (1982) and Chinese-American Qiu Chengtong (1949-), the first to win the Fields Prize, became the first China mathematician to win this honor. Fields Prize is the highest prize in international mathematics. The prize is awarded every four years to mathematicians under 40 who have made great contributions to mathematics. Qiu Chengtong was born in Guangdong and later moved to Hong Kong. He lost his father in his early years and his family was poor, but he studied hard and became fascinated with mathematics in middle school. Later, he was valued by the famous mathematician Chen Shengshen and was admitted as a graduate student. Under the guidance of Chen Shengshen, she completed the postgraduate course in only two years and obtained a doctorate. She is only 22 years old. He became an associate professor at the age of 25 and was promoted to full professor at the age of 28. Later, he became a tenured professor at Stanford University and Princeton Institute for Advanced Studies. 1976, 27-year-old Qiu Chengtong solved the famous problem of differential geometry-Calabi conjecture, and applied differential equations to differential geometry, which promoted the development of differential geometry and differential equations, and became the youngest scholar in this field, famous overseas. 1979, 30-year-old Qiu Chengtong was awarded the honorary title of "California scientist 1979" by the California Museum of Science and Technology. He was the first mathematician to win this honor. 198 1 won the Van Xilun Prize again and the Fields Prize in Warsaw the following year.
