Hello, recently a person posted a part-time advertisement in the group, saying that he wanted to recruit fashion magazine models.

I suggest you be more cautious about this matter. First, let's see if it's normal for you to join this group. Talk to friends in the group, listen to their opinions and see if they are cheating. Don't sign a contract blindly, you can consult some professional hospitals to see if these things are reasonable and legal, so as not to be deceived.
