What should a person do if he has done something wrong? Will he be punished?

It is not terrible for a person to do something bad. What is terrible is that he knows it is a bad thing and will do it again. You can live a safe life without doing anything wrong. If you do something wrong, you shouldn't try to deceive yourself by telling fortune. You can hide for a while, but you will never escape. What should be returned must be returned, and what should come will definitely come. If you are near, you will report "disaster to yourself" quickly, and if you are far away, you will report "disaster to future generations". Only when you wake up and repent, always have a kind heart and do more unknown good deeds, that is to say, more "accumulated virtue" may offset the guilt of doing something wrong.
