Unreasonable, children in the sixth grade are usually only thirteen or fourteen years old and belong to people with limited capacity for civil conduct. As far as your description is concerned, if you simply push and pull the glass door to cause injury, it is wrong to learn from others. Because schools, as places for minors to study, have the obligation to ensure the safety of their equipment.

To take a step back, even if the glass door itself is fine, the school has the responsibility to manage the behavior of underage students during school study (including recess), and the school also has the responsibility to manage the fighting between students.

Therefore, according to the provisions of Article 39 of the Tort Liability Law, if a person with limited capacity for civil conduct suffers personal injury during his study and life in a school or other educational institution, the school or other educational institution shall bear the responsibility if it fails to fulfill its educational management duties.

This responsibility should be borne by the school first.

As for the students, do you want to pay with the teachers? Personally, I don't think it is necessary to pay compensation, although Article 28 of this Law stipulates that the damage is caused by a third person, and the third person shall bear the tort liability. Generally, fighting between students causes damage to the glass door, which should not be considered as caused by another student. In addition, even if there is a teacher's management fault, it should not be caused by the "third party" mentioned here. The school has no right to ask the teacher for compensation, but can only ask the teacher to bear internal responsibility according to the school's management regulations on teachers.
