I was hired as a personnel clerk by Shenzhen Fu Ying Electronic Technology Co., Ltd., with a probation period of 2200, but I have to do general work in the workshop for half a month. Is it a scam?

There are such swindlers in many places in Shenzhen. They recruit people in various names and then take people to work in some small factories. Nominally an internship, in fact you are a temporary worker in the factory, and your salary is settled between the factory and the liar. When you find yourself cheated, you won't get a penny except a complaint. I suggest you leave without saying a word as soon as possible.
