Of course, the strongest department of mathematics in China is Peking University, followed by Chinese Academy of Sciences. I come from Institute of Mathematics, China Academy of Sciences. It should be said that the students of Chinese Academy of Sciences are not as good as those of Peking University. After all, the best students in Tsinghua of Peking University either go abroad or stay in our school. Generally, the students who come to Chinese Academy of Sciences are top students from second-rate universities in domestic universities, but there is still a gap compared with Tsinghua of Peking University. But the teachers and hardware facilities of the Chinese Academy of Sciences are absolutely the best in the country. If nothing else, the number of academicians is enough to overwhelm other schools. The accommodation and treatment of Chinese Academy of Sciences students are also unmatched by other schools. If you want to take an inter-school exam, you can recommend it to the Chinese Academy of Sciences. Our scores in basic mathematics are not too high. After all, not many people are willing to learn basic mathematics. As long as you are good at mathematical analysis and advanced algebra, it should not be difficult to get into the exam.

In addition to these two schools, Fudan University, Nankai University, Tsinghua University and the Mathematics Department of Beijing Normal University are also good schools.
