First, parents should find out the truth of the matter. Understand the cause and effect.
The difference between counterattack and revenge
If your child is fighting back to protect others, you should confidently tell your child that there is nothing wrong. If it's revenge, right or wrong, tell him it's not the right way.
Respond to the teacher
In school, we should resort to "law" to respond to teachers and seek solutions.
Communicate with the teacher
Sometimes the teacher's criticism here is to calm things down first, and don't make it worse. This is a common strategy used by teachers. Please understand the teacher, parents should communicate with the teacher, so that the teacher will bring your child to talk about the reasons for criticizing him afterwards. Of course, it is not excluded that the teacher will "rub" him.
Solve the problem correctly
The purpose is to let children solve problems in the right way.
