People in the same village owe you 500 yuan. You should talk to him before or after she gets married and tell him that you can't make trouble on her wedding day. Because people are not happy to get married, and they only get married once. If you take revenge on him, then you have broken the law and committed a crime. Never do such a foolish thing. If there is evidence, he owes you 500 yuan, which is really not for you.
