The teacher's behavior of beating and scolding students violates the Teachers Law and the Compulsory Education Law, which is not conducive to students' physical and mental health.

The harmfulness of teachers' corporal punishment of students is as follows:

1, it is difficult to change students' incorrect attitudes. Although corporal punishment may achieve the purpose of stopping a certain behavior in a specific situation, it is difficult to change students' incorrect attitudes. Corporal punishment and disguised corporal punishment can only help students learn to avoid corporal punishment, instead of sincerely changing their attitudes and correcting their mistakes. This kind of corporal punishment and disguised corporal punishment are relatively ineffective.

2. It is difficult to form a good educational atmosphere. The corporal punishment of "setting an example" makes students behave cautiously, always defensive and afraid of teachers. This is not conducive to the formation of students' positive and diligent ideological quality, nor to the formation of civilized, harmonious and relaxed atmosphere in the class.

3. Corporal punishment and corporal punishment in disguised form will bring unnecessary anxiety to students. This is not conducive to the cultivation of students' healthy psychological quality, but will damage students' physical and mental health. Frequent corporal punishment will increase students' extreme aversion to corporal punishment, and students will be slow to respond to corporal punishment and gradually lose their sensitivity to corporal punishment. In order to achieve the ideal effect, teachers often have to increase the intensity of corporal punishment, which leads to a vicious circle of corporal punishment and the consequences of education are unimaginable.

4. Corporal punishment will also lead to tension between teachers and students, which will lead to conflicts and even confrontation between teachers and students. This not only damages the social status and personality charm of teachers, but also violates the Law on the Protection of Minors in People's Republic of China (PRC), the Law on Compulsory Education in People's Republic of China (PRC) and the Law on Teachers in People's Republic of China (PRC).
