Legal analysis: at present, it is generally nine-year compulsory education, but in some areas it is 12 years compulsory education. Twelve-year compulsory education refers to bringing high school education into the scope of compulsory education and implementing twelve-year compulsory education. China Special Economic Zone, ethnic minority areas, Zhejiang, Guangdong and Hebei have all tried free high school education and achieved good response. However, it is mainly concentrated in ethnic areas, coastal areas and other developed areas, and has not been widely popularized.

Legal basis: Article 19 of the Education Law of the People's Republic of China. The state implements a nine-year compulsory education system.
