Being notified of being late for class is not a punishment. Because in school, the school has its own rules and regulations, students must strictly abide by the corresponding rules and regulations of the school, otherwise they will be punished by the school. If the punishment has not been revoked when they graduate, they can't graduate normally. Informed criticism is not a punishment. There are five kinds of punishment: warning, serious warning, demerit recording, detention for examination and expulsion from school.
