University funds generally come from national finance and local finance. The higher the level, the more funds you get, and then the income-generating ability of the university. For example, in Tsinghua, the income-generating capacity of Peking University is as high as one billion, and the income-generating capacity of R&D is also very strong, which is 985 times that of other top universities. Shanghai University has a low level, limited funds, less funds and limited research and development level.
