First, there is no such thing as paying training fees before going to work in basically all occupations.

Second, even if training fees are paid, regular companies will explain why they have to pay training fees and where the money is spent. And after the training, can you officially take up your post? If not, you must find out whether the training fee can be refunded. In some places, after the training, you say no, you don't pay for nothing.

Third, again, the training fee of the regular company will be deducted from the salary of the month, instead of asking you to pay cash directly, understand? If you really want to pay cash, you must ask me the second point, and if you really want to pay, you must have a receipt and an official receipt stamped by their company, indicating the training fee, how long and how much. In case of any situation, you can also take this to the labor bureau or the public security bureau to complain and report the case, saying that it is fraud, and this labor bureau and the public security bureau will take care of it.
