How to perfunctory colleagues' questions in the workplace?

In the face of such a colleague, it is actually very simple for you to perfunctory, that is, whenever he comes to ask you, you pretend not to hear, or do something else, leaving him alone in a daze.

But the relationship between colleagues should be well maintained. Although his behavior is a bit unbearable, at least he still has the idea of making progress. So my suggestion is that you can teach him how to do it, and you can do it. As for his bragging in front of the leader, you can also tell the leader that he is studying very well now. You can ask the leader to assign him a job and see if he can finish it.
