Operation method
First of all, many head teachers will choose to let students write a review when they punish students. In fact, this is also a good choice.
Then, now it is not allowed to physically punish students. The head teacher can call the students to the office to do ideological work for them, or have a good exchange with them.
Then, he can be punished for cleaning. The deadline depends on the severity of his mistakes, but it should not exceed one week.
Finally, if he makes a mistake in the class of the head teacher, he can be punished to stand in the back of the classroom to listen to a lesson.
