Teachers always make fun of their students.

Every teacher's morality is different. Teachers with good moral character love their students very much. Whether they are clever or sincere, they will patiently tell you how to solve every problem. The difference is different. When students are found to have made some mistakes, they will use their authority to deal with them. Some teachers look down on students without strong parents and so on. This is a person's moral character, teachers are also people, and there are three or six grades. I see it this way. You have a good job now and there is room for development. Don't care about such people. If you don't violate the principle, help him once, but say what you thought in those days diplomatically, and don't hurt other students in the future.
