In China, it is stipulated that students can only attend the first grade at the age of seven. From grade one to grade three, there are nine years. Every student has the obligation to study in these nine years. The country calls it nine-year compulsory education. From the age of seven, it belongs to the age range from nine-year compulsory education to sixteen. Schools and parents have the obligation to supervise and educate students to complete their studies, so education from the age of seven to the third grade is compulsory.

Compulsory education is a basic public service for all school-age children and adolescents. It is the legal responsibility of the government to provide basically balanced compulsory education. Every school-age child should have equal opportunities to receive qualified compulsory education. The nature of compulsory education determines that compulsory education must develop in a balanced way. Promoting the balanced development of compulsory education in the region will be accompanied by the whole process of narrowing school differences and improving education quality. Promote the balanced development of compulsory education in urban and rural areas, and gradually narrow the gap between urban and rural areas with the development of urban-rural integration. To promote the balanced development of regional compulsory education, we must solve the problem of regional economic and social imbalance and improve the education level in the central and western regions.
