Wei Dongyi won the first place in the Shandong Mathematical League in high school, participated in the 49th and 50th International Mathematical Olympiad held in Spain and Germany, got full marks respectively, and was sent to Peking University. At Peking University, it took me eight years to finish all the courses of this master's degree. During his study, he won the gold medals in China, Japan and Korea.

The research direction is PDE problem and random matrix in fluid mechanics. His fluid stability direction belongs to the difficult and high-tech problems in PDE and even the whole mathematics, and it is the core problem in PDE and even the whole mathematics research. Wei Dongyi is already a rising star of Ran Ran in the field of international fluid, and basically everyone who does fluid knows a little about his work. In addition, he also developed the pre-solution estimation method and wave operator method, which solved a series of important open problems in the mathematical theory of flow stability.
