How about Shanghai Huali Microelectronics?

There are only a few fabs and the circle is very small. Basically, you just muddle along and get tired to death. In addition, your education level is not high, and there is little hope of promotion. You can design it if you can, but now the economy is depressed and the semiconductor industry is not so good. Unless you change careers, if you are still interested in this industry and have no other work to do, I suggest you do it first.
