Many doctors who came back from overseas think that being a teacher in a university is a good choice for many people, so the competition is fierce. In fact, what kind of university a teacher enters has a lot to do with the university where the doctor graduated. For example, if you are from Harvard and Yale, it will be relatively easy for you to become a teacher in 985,211college. It's not difficult for you to go to the first-class schools in China, such as Peking University and Tsinghua.

But if the university you graduated from is not 985 or better, it will be more difficult for you to enter a university above 985.

This is the first aspect: the level of doctoral institutions. In addition to graduate school, it is actually more about your thesis and related projects, topics and achievements.
