1, Wei Dongyi has made great achievements in the field of mathematics, and although He Youjun also has excellent mathematical ability, the specific performance in this field is still unclear. IMO and Wei Dongyi, who represent intelligence contests, can rank among the top three in China and eighth in the world.

2. Wei Dongyi, Peking University, China, is a researcher in the Department of Differential Equations, School of Mathematical Sciences. He is the focus of the whole younger generation of mathematicians in mathematics. He Youjun, a two-time international Olympic gold medalist, has a high IQ and was admitted to the mathematics department of MIT, a top university, but Wei Dongyi is better in the field of mathematics.
