First of all, you think the head teacher is excellent, usually because you make mistakes and always stare at the people who make mistakes. So making as few mistakes as possible can be effectively avoided. For example, my head teacher in high school will take you out to talk at noon as long as you don't behave well recently. A talk is a noon. You can take a nap during your lunch break. As soon as you speak, this lunch break will be gone. So many students don't want to be dragged out to talk by the teacher, and they have never seen such a talking teacher. But I was dragged out to talk only once in the whole high school, mainly because I usually behave very well and don't make trouble, so the teacher naturally has nothing to say to me.
What's more, the top class teacher who can't stand it can choose to change classes, because when he was in junior high school, the class teacher felt a little abnormal and seriously lacked teachers' morality. As long as he comes to patrol and finds someone talking, it's two slaps when he goes up. And once someone called him by his first name when he was cleaning, or he was knocked down when others heard him. I suspect that this must be a fake teacher, maybe a local ruffian. Later, a classmate couldn't stand the torture and asked for a shift change directly. The family came to the school to make trouble, and there was no way to change to the next class. All the troubles were solved.
There is also the reaction with the school leaders. If some teachers violate discipline, such as beating, cursing and insulting students, they can report it. If the school doesn't care, go to the Education Bureau. As long as there is definite evidence, such a top-notch teacher can be dismissed.
To tell the truth, it doesn't matter as long as the teacher doesn't hurt you very well. After all, teachers use all means to discipline their students, both for their grades and for their own good.
