Schools are places where scientific and cultural knowledge is disseminated. Among them, teachers are disseminators of scientific and cultural knowledge, and students are recipients of scientific and cultural knowledge. Scientific and cultural knowledge is not a teacher's patent, and there is no school property right in it, so teachers or schools have no right to sell scientific and cultural knowledge to students or parents as their own goods. Teachers only have the obligation to spread scientific and cultural knowledge, but have no right to charge students. In teaching, although teachers have paid teaching labor, this kind of labor is the obligation teachers should do to their students. Your teaching labor is paid by the school, so you can't charge students any more. So where does the school pay the teachers? It depends on the nature of the school. If this school is a public compulsory education school, teachers' salaries will naturally be borne by the state finance; If this school is a private school, teachers' salaries should be borne by private sponsorship or donation; If this school is a vocational school, teachers' salaries should be paid by the industry or enterprise that founded the vocational school. No matter what kind of school, the tuition fees paid by its students are the students' learning expenses, not the education expenses, not the teachers' education expenses.

To put it more seriously, it is "gluttony" for teachers to charge students, and it is "cannibalism" for schools to charge students' parents. China is a socialist country, and there should be no cannibalism in education in socialist countries. On the issue of education, we should maintain a little socialism and be less market-oriented. Education in China should go its own way. China's economy can be marketized, but China's education can't be marketized. We should engage in a socialist market economy, but we cannot engage in market education without socialist nature.
