What about the general electronic treatment of Huayang, in terms of work welfare?

I have a classmate who is doing R&D there. He is a master student and has worked for more than two years. Now I earn more than 8,000 yuan a month, including accommodation, eating in the canteen, paying 1 social security, working five days a week, and paying 5 social security and housing accumulation fund. The salary is ok, but it is difficult to get promoted. He estimates that it is not easy to be a supervisor and it is not easy to get a higher salary.
