Dongan engine (aero-engine), master of materials science, heat treatment and casting technology. How about salary and work intensity? Thank you.

Dong 'an is not so good. Worked as an intern in 2003.

Especially in the foundry workshop, the workers said that the designers were graduates from some agricultural colleges and knew nothing about casting, so the drawings they drew could not be made. Tell them a theory and they give a convincing answer.

Some parts of worm shaft engine need casting. The quality of airmail is very high. You know, the defective rate is very high, but the top management doesn't care about it. The higher the qualified rate, the better. The workers said it was nonsense.

The wages of workers are about two or three thousand, and some people get seven or eight hundred after the deduction.
