Peking University is indeed one of the top universities in China, but when ranking universities, the reference object is the comprehensive ranking of universities, which should be positioned according to the rankings of all disciplines offered by universities. Even Peking University can't conclude that all its projects are ranked high in China. For other universities with weak comprehensive strength, it is normal to specialize in only one aspect.
When ranking universities, the reference object is the comprehensive ranking of universities. People's cognition of universities mostly stays at the level of comprehensive ranking. If they don't pay much attention to it and don't know the separate ranking of a major in each university, it will lead to a wrong judgment on the strength of the university.
Peking University can't conclude that all its projects are in the forefront of the country. The comprehensive strength of Peking University is indeed very strong, but for Qufu Normal University, they put more energy into the research of the Department of Mathematics, which is higher than Peking University's investment in the Department of Mathematics of our school, and will naturally get better results.
If you specialize in one aspect, you will still be good at it. Peking University is a university with strong comprehensive strength, but if it is comprehensive and perfect, it will be another level. Peking University is ahead, but it can't be said to be the first and second. We should reasonably recognize the efforts of other universities.
The mathematics department of Qufu Normal University ranks higher than Peking University. Do you agree?
