According to the Compulsory Education Law of People's Republic of China (PRC), compulsory education is compulsory for all school-age children and adolescents, and the state must guarantee it. The quality of compulsory education is related to the healthy growth of hundreds of millions of children, the development of the country and the future of the nation. This is a national regulation. From the local level, local governments regard compulsory education as the top priority of education investment and effectively guarantee it. Therefore, the class fees of public high schools are borne by the state finance and do not need to be paid by parents.

Class fees refer to the extra fees paid by students, usually according to the course arrangement, and a certain fee is charged for each class. Generally speaking, the class fee is charged according to the actual class time of students, so it is also called class fee.
