Teachers compare students, because parents' income is divided into students, which brings bad education to students, and students feel that parents' income is different. This wrong educational concept will have a bad influence on students. Students are all equal, and teachers should treat them equally. Parents' income has nothing to do with students coming to school for education.

There are also cases where teachers violate professional norms: teachers rely on their own resources and contacts at school to set up cram schools outside the school to make profits for themselves. I watched a TV series recently, and there was such a phenomenon in it. The teacher took advantage of the parents' desire for their children to study hard, so many parents reported their children to expensive cram schools outside, and learned a lot of knowledge that could not be learned in class before they went to class. This violates a basic teacher rule. The primary duty of teachers is to teach and educate people, and to give their knowledge to students as much as possible, so that students can master it well, instead of using students as tools for profit.

Another way is to make students realize their mistakes, that is, to beat and scold students in class because of their mistakes. This kind of guidance is incorrect. There are still some teachers who have this old idea that students are disobedient, should they? Punishment? Only in this way can students correct their mistakes. But I don't want to think about whether this kind of behavior will have a bad influence on students' psychology or hurt them. Teachers should educate students to serve others with virtue instead of solving problems with violence.

Many times, teachers don't teach students in the right way. Students are a blank sheet of paper, in which teachers play a very important role. What kind of teachers will hand over what kind of students, teachers' words and deeds in daily life may affect students invisibly. Teachers must standardize their words and deeds and instill good manners and habits in students. Before learning knowledge well, they must first teach students to be human.
