As for Shanghai Dai Yi, Shanghai Longchuang and Tongji Tong Jie, they are all design companies in the automobile industry. Everyone in the industry knows that the internal turnover rate of design companies is very high, and there is basically no future. At first, I thought Tongji Tong Jie was awesome. Later, I learned that it was LJ. Now they are all going out of business, and the other two are not much better.
Shi Kejia is a research and development center, and has undertaken many projects of Chery. He has a deep relationship with Chery, but Chery has a hard time, so his life is also hard.
Magna is a foreign design company, which looks ok, at least the salary is quite high, and many friends work in it.
However, the above companies are all large and comprehensive, involving specific CFD, and they are not very professional.
