Ask an expert ~ ~ about the recruitment examination of air traffic control system controllers.

You mean you didn't take the three-school entrance examination? To enter the control post, you must have a certificate of joint examination of three schools (if the relationship is excellent, it is a cloud). If you miss it, you still want to stay in the control industry, 1, repeat one year for 2,4+13, and take the airport control exam (actually, it's not bad, you can change jobs after taking the control license). Personally, I recommend the third one, which is proven and easy to find a job.
