It is reasonable to criticize and educate students who have not finished their homework, but it is too much to hit people, especially a male teacher. If a boy is beaten, he can be far-fetched, and so can a little girl. He should respond to the superior leader and give the teacher some warning, but don't make too much noise unless you are sure to let the school expel him. After all, you have to get along with him in the future, so be careful of his revenge.
