In Chinese schools, how do some teachers deal with "rebellious" students?

First, embarrass them publicly at school, making them lose face, including but not limited to telling the student, "Look at who in our class has good discipline in studying, and look at you." This is called public comparison, praising one and criticizing the other.
Second, require the student to stand in front of the podium and speak, saying, "Come to the front so everyone can see you," showing the mistake. This is called collective gaze, a disguised form of public shaming.
Third, arrange for them to sit in the corners of the podium, or alone at a desk next to the trash can in the back row. This is called a problem student’s exclusive seat.
Fourth, teachers might say, "Because you’re not allowed to participate in PE class, you have to do extra homework for the whole class." Once this is said, listen to the collective complain with elongated tones—this is called one person’s mistake causing the whole class to share the hatred.
Fourth, call on other students to evaluate the misbehaving student. "Everyone, how do you think he usually performs? What do you think he’s done wrong? What are his shortcomings?" This is called collective judgment, public criticism.
Fifth, teachers might exaggeratedly imitate the student’s mistake and tone, provoking laughter from the whole class. This is called deliberate ridicule, using others for entertainment.
Sixth, teachers openly give students nicknames, treating students as invisible or using cold violence, which are the most common methods.
