What do people say about playing billiards and shaving their heads?

First show that you will pay attention to each other's performance, and then show that you are looking forward to it. When playing table tennis, shaving one's head refers to the situation that the opponent is not sealed in the game, so when the opponent says shaving his head, he can first show that he will pay attention to the performance of the other party, and then show that he wants to see if the other party has such ability and express his expectations. For example, if you want to refuel, I want to see such a scene.
