How to deal with a colleague like this?

Don’t be afraid of other people’s opinions. Everyone will see more clearly. This kind of person will not be liked by others. There are two ways to deal with this kind of person: one is to praise him when you meet him and praise him every day. , let him be arrogant, and someone will naturally deal with him at a certain time, but this requires your psychological quality to be quite good. The second method is not to pay too much attention to what he says. Talk to him like you talk to other people, but don't take the initiative to talk to him, and be neither humble nor arrogant. If he makes fun of you, you can let him go twice. You can tell him directly three times. I'm very angry when you say this, but I won't argue with you. I've already told you twice. I hope there won't be similar words in the future, so that he won't do anything to you again. Yes, muster up the courage to give it a try, it will definitely work.
