Parents of school leavers agree to the short message format.

The head teacher should make things clear in a realistic way, and measure the students' behavior according to the discipline and rules of the school. On the one hand, students' rebuttal on the spot may show that students are making trouble unreasonably. On the other hand, students may not take the discipline and rules of the school seriously and think that they can do whatever they want, which is not a big problem. When dealing with students in the presence of parents, the class teacher must announce the discipline and rules of the school, and everything will be done in accordance with the regulations.
