What's wrong with hitting people? It's over slowly. However, you have to bear it properly. Otherwise, the result will be very bad. It's best to show your strength. Don't show weakness. It's just a matter of mentality, not a matter of fists. If you want to rely on the teacher to solve it, forget it. I can fight a few while standing, and I am not afraid of pain. You are human, so is he. Too fair.
