Colleagues are always upset with you because of some small things?

Your colleague is obviously putting on a show. If the atmosphere of the company is really what he said, you are recruited by him and brought by him, and you need his person in charge, I suggest you talk to him privately and say that you appreciate his recruitment and teaching at work. However, your face is just his face. If you always talk about you in front of leaders and colleagues, will you tell everyone again that you didn't treat you well on weekdays and hurt your face? Talking to him in this way can discuss how to deal with problems in work.

If he is a pure theater man, he likes to show it to everyone like this. I haven't taught you anything, so you don't have to pay attention to him, do your job well, and then apply for a change of leadership when the time is ripe!
