Why don't graduate students want to join China Railway 12th Bureau?

Space constraints. China Railway 12th Bureau is a large state-owned enterprise with relatively fixed organizational structure and many levels, which leads to limited promotion and development space, and graduate students are unwilling to enter China Railway 12th Bureau. Postgraduate education is a kind of national education, which is conducted by ordinary colleges and universities with master's and doctoral degrees. After graduation, a graduate student can also be called a graduate student, which means a person with a graduate education.
