Yes, teachers' morality has regressed. Everyone is looking for money, and the teacher is no exception. Let's say Mr. Yu, my head teacher in the first to third grades of primary school, is really good and really amiable. I transferred from another school to teacher Yu's school in the next semester, in the first grade of primary school. The first day, I cried all the time because I was timid. Teacher Yu hugged me, coaxed me, played the piano for me, and the math teacher told me stories. Teacher Yu is very kind to every child, whether it is a classmate with good grades or a naughty classmate with poor grades. Unfortunately, she later died of a serious illness. I will always think of her and miss her. On the other hand, the head teacher of my child's first or second grade is really bad.
