The reason why so many people want to take the postgraduate entrance examination is to improve their academic qualifications. But with the development of time, there are more and more graduate students. Therefore, in the face of some Xinyi enterprises, graduate education is not so scarce. It is not feasible to regard graduate education as your competitive advantage.
Secondly, in the postgraduate stage, there are also complicated interpersonal relationships. In the postgraduate stage, students' grades are closely related to their tutors. So some students will never graduate if they don't handle the relationship with their tutors properly. Some tutors will treat graduate students as free labor to help them work.

Choosing to go to graduate school is equivalent to spending two or three years studying. Those students who did not choose to take the postgraduate entrance examination have been in the society for two years. These two years' experience will make these undergraduates grow faster, while those who study in graduate school have learned more theoretical knowledge than others for several years, but some units really require ability when looking for a job. In particular, some students take the postgraduate entrance examination just to mix academic qualifications, and they don't have a good experience of themselves in the postgraduate stage.
