What about Shanghai Zhongxing Technology Co., Ltd.?

It's not very good there. There will be basically no salary increase after going in. The salary is 250 yuan. It's nice to get a salary increase every two years. If you go to guard the R&D department of the treasure, I suggest you not go. That department is a mess, everyone has a relationship, only irrelevant people work, and the credit is not yours. If something goes wrong, you are still responsible.
