Who knows about the career establishment positions of such units as East China Air Traffic Control Bureau?

This so-called career establishment is generally composed of public institutions and front-line operating units. Front-line operating units only recruit transportation majors (only three universities have this major: civil aviation university of china, Guanghan Flight Academy, Nanjing University of Aeronautics and Astronautics), meteorology majors, communication and navigation majors, and social recruitment is not allowed. Among them, the transportation major is a three-shift system running 24 hours a day. My job is air traffic control and command. The income from work is ok, but it is hard, and only three college graduates are recruited.
