The parents will definitely go to the teacher and ask them to apologize. If it is serious, they will even expel the teacher from school. Therefore, for teachers, it is ok to punish children, but there must be a degree to make children feel that you are punishing him, not hitting him and hurting his heart. Just a while ago, another teacher beat the students and asked their parents to find the Education Bureau, which fired the teacher.
It is understood that because the final exam is coming, the teacher asks the students to read books and review their lessons in class. However, when the head teacher inspected the class, he found that the students had no discipline and made a lot of noise in the class. So as a class teacher, I felt very angry, so I slapped dozens of students' palms with a so-called ruler. Maybe students feel particularly wronged and tell their parents when they go home. So what happened later, I think the teacher's punishment method is really unreasonable, because he didn't find those students who really spoke, and there must be some students who were beaten by him who were particularly quiet and introverted.
He doesn't like getting into trouble in class, but the teacher will do great harm to his heart. He felt that he had done nothing wrong, and the teacher hit me, so he felt particularly wronged, unlike the naughty child who had been in class all day that day. Even if you hit him a few times, he won't have a problem, be sad or complain.
Therefore, as a teacher, we must punish students in a reasonable way, but don't hurt children's self-esteem, because they are still young and immature physically and psychologically. It is possible that your violent punishment will have a very bad influence on their study and life, and so will a parent. If it is really for the good of children, then some punishments for teachers are acceptable, and only teachers can cooperate with schools to train children in many ways.
