Article 35 of the Teachers Law stipulates that: those who insult or beat teachers shall be given administrative sanctions or administrative penalties according to different situations; Causing damage, shall be ordered to compensate for the losses; If the circumstances are serious enough to constitute a crime, criminal responsibility shall be investigated according to law.
It is not necessarily illegal for students to abuse teachers at school. If the influence is not bad, it can be dealt with lightly as a moral issue. Serious influence, great influence on the teacher's reputation, will also constitute libel and insult.
