Did you graduate from civil aviation university of china majoring in aircraft power design or did you repair aircraft for maintenance? I heard that maintenance is difficult and the company is not high. The mechanical and electrical majors of Civil Aviation University basically go to airlines to repair planes, that is, to maintain them. Hard-working, blue-collar, classified as workers. Master graduates can stay in school to teach or be teachers in training centers. If you are willing to go to the company and start as an undergraduate, you will have a more optimistic development prospect. But the maintenance work is really profound, and a master's degree means nothing. Compared with undergraduates, it may be like running 5000 meters. You ran 0 ahead of schedule. 0000 1 sec. I graduated from Civil Aviation University majoring in mechanical and electrical engineering, and my working hours are not long, so I belong to the front line of maintenance. My job is hard, but I love it very much. No matter what career you choose in the future, if you want to gain something, then remember: don't treat it as a job, treat it as a career. I wish you success!
