I worked there for three months, and my salary was piecework. Following the automobile industry, there are off-season and peak season. You can earn more than 2500-3000 in the peak season (summer). Most people work 12 hours a day, at least 8 hours.
North factory accommodation is a dormitory. You'd better not go, the conditions are not very good.
The welfare is still good, and I will pay you labor insurance when I work for a certain period of time.
