Tuition refers to the cost of going to school and running a school, which is the fund for the operation of the school; The fees that students should pay for studying at school as stipulated by the school. The teaching level, hardware equipment and other conditions of each school are different, so the cost required to maintain the operation of the whole school is also different, and the teachers are also mixed, resulting in different wages to be paid.

The tuition fees of public schools in the non-compulsory education stage need to be used to pay the public expenses of schools, such as water, electricity, tables and chairs, chalk triangles and so on. These are all tuition fees, and the insufficient part needs to be supplemented by local finance. If it is a private school, all expenses of the school depend on students' tuition fees, from desks and chairs to teachers' salaries, and even the money for the school to buy land in Gai Lou should be gradually earned back from students' tuition fees.
