Class cadres are keen on "watching the theatre", which is actually a feeling of schadenfreude. Not only the class cadres, but also others will boo when the teacher punishes the students. Class cadres are generally the people who have the best relationship with teachers, and teachers usually punish class cadres with corporal punishment. Those heckling class cadres have a sense of superiority. If they are punished by corporal punishment, the degree of corporal punishment will be lighter, or even not, and they will feel spoiled. Moreover, they are keen on booing, and to put it bluntly, they are still psychologically unhealthy. It is not the right way for teachers to punish students. Teachers can educate students in thousands of ways, and corporal punishment can be said to be the worst way of education.
The class Committee booed, and the class cadres, in the final analysis, had bad conduct and watched others be punished, but they were not punished. Their schadenfreude is a mockery and disrespect to them. The object of ridicule is naturally the corporal punishment, and their behavior will cast a shadow over the psychology of the punished. It's like making a fool of yourself, others don't understand, just watching the play.
Class cadres should be elected by students and should be the embodiment of students' will. As a class cadre, we should think from the perspective of ordinary students. Class cadres serve the class, not the privilege.
