How about Hangzhou Keting Optical Technology Co., Ltd.?

A degree is more important there. The pay for college students is pretty good. They worked at the grassroots level for a year or two and then were transferred to the top. But it's quite hard and there are night shifts. It's very tiring. Usually many people can't stand it and leave without doing it. If you are not a college student, there is almost no chance of promotion there. And very tired. The general salary is around 2,000~3,500. The salary depends on your output. Holidays are not a national standard either. It will be hard. 12 hours a day. Two shifts.
