The fight after drinking is not serious, and it is determined to be a criminal case.

Hello, your case is a simple public security case, because I can't see anyone with minor injuries from your description, which shows that this case is not a criminal case at all, and you don't need to compensate the other party's money. If you have evidence that the other party took the opportunity to ask for your money, the other party may be suspected of extortion. I suggest you hire a lawyer to help you with this case.
