Is it reliable to find an airport controller on 58?

Not reliable. Basically, there are many fakes, and the airport is strict in recruiting employees. The airport has its own recruitment channels. Basically, you don't put recruitment information on channel 58. You can also contact them, but be careful. Don't pay any fees, because the basic fees are fake. Airport controllers usually sit in the monitoring room on duty. The responsibility is to check whether all the visual angles of the monitor are safe, whether there are potential safety hazards, whether the fire-fighting equipment is operating normally, and patrol the building.
