Is KTV recruitment in Meng Xi Park a scam?

This is just a scam. You haven't signed the contract and paid the probation salary, have you?

I will ask you for money in a few days on the grounds of health certificate, XX certificate, clothing deposit and so on.

Get your id card back quickly. This is a handle. I can't do anything with my ID card.

Remember, when you go out to work, you should be careful in all your work. 90% of them are liars, because regular companies don't pay the deposit in advance. Unless you sign a contract and become a regular employee, it may involve money.
