Can graduate students of civil engineering and water conservancy go to CCCC No.4 Middle School?

Graduate students of civil engineering and water conservancy can go to CCCC No.4 Navigation Bureau. Judging from the relevant public information, it is not easy for graduate students to enter the four universities of the Institute of Aeronautics and Astronautics. The full-time employees of this company are highly educated, and more than half of them are masters and doctors. Their regular employees only recruit doctors and masters, and undergraduates and junior college students can only do labor dispatch. The treatment and welfare of labor dispatch employees are much worse than that of regular employees, but they can still be converted into regular employees after two or three years of good performance.
