Which KTV in Xi'an is recruiting young masters for part-time work?

Recently, there are many nightclubs in Xi'an, such as KTV bars, that say they are recruiting part-time male waiters. But after you go there, they will go through the entry procedures for you and you have to pay 400-600 yuan. With the money, you can go to work at night, but there is no business at all? There are many people waiting in the human resources department, waiting outside for interviews. Waiting for interviews is actually waiting for payment. After paying, they go to work in the evening. There are not many customers, and no one can go to the box.
