It doesn't matter if universities don't join departments, but joining some departments can better exercise themselves.

1. University is a cultural institution with unique functions. It is an institution of higher learning that is interconnected with socio-economic and political institutions. It firmly inherits, studies, integrates and innovates advanced academics. It is not only the product of the development of human culture to a certain stage, but also a unique university culture gradually formed on the basis of long-term school-running practice through historical accumulation, self-efforts and the influence of external environment.

Second, universities have a history of thousands of years since their birth, which can be traced back to their birth at the earliest, and developed mainly from Germany, Britain and other countries. Modern universities in China originated in the west, and western modern universities gradually evolved from European medieval universities, British universities and German universities to American universities. No matter which era, universities are the creative inheritance of previous universities, not the negation.
