Free textbooks for compulsory education are Chinese textbooks, mathematics textbooks, English textbooks, ideological and moral textbooks, physical education textbooks, music textbooks, junior high school textbooks, political textbooks, history textbooks, physics textbooks and chemistry textbooks.
Free textbooks in primary schools and junior high schools are not exactly the same, and there are relatively few in primary schools because there are more subjects in junior high schools.
Primary schools basically only have Chinese, mathematics, foreign languages and natural science ideology and morality.
Moreover, there are many textbooks on physical chemistry and political history in junior high schools.
