In short, China's higher education pays attention to the mastery of ideological and political knowledge, while western higher education pays attention to the cultivation of ability and the improvement of quality. So China is strict and lenient. After entering, it is basically a herd management. Unless you don't graduate, basically teachers and schools will chase you to graduate; In the west, the entrance is wide and the exit is strict. If you don't have the ability to study independently and have no good ideas after entering, you may not graduate, and it is normal to postpone graduation.
