It's not like this there now. I am also a middle school student. The canteen you mentioned is a relative of the principal, and it has nothing to do with the teacher. The teacher's responsibility in school is to teach students well. If you get involved in too many problems, you are sure to cause more trouble. You should be a young teacher, hehe. Deduct the most perfect self in one's own post, so that subordinates admire and superiors are satisfied. Do it,
