Traditional education has four components, which everyone should accept all his life, including family education, teacher education, continuing education, social education and understanding education. A person must accept and practice these four kinds of education in his life, so that he can succeed. There is only one school education left in the modern education system, plus at most one social education. Both of them focus on imparting knowledge and training skills, which is not the whole of education. The essence of traditional education is to teach humanity, life, Ming Dow and behavior, that is, how to be a man. Only adults can do things. If you can't be a man, you can't do things. The first sentence of Han Yu's "Teacher's Theory" is "Teachers preach and teach students to solve doubts", which is the way to help students make a living naturally and teach them to be human. Knowledge transfer of knowledge is secondary. As the saying goes, "I have spare capacity to study literature". If there is no spare capacity, I would rather not teach or preach first. If you don't have sex, the teacher won't let you out of the mountain. If you insist on leaving, the teacher will expel you. This is not that the teacher deliberately makes things difficult for you, but that he is really responsible for you.
