Since the fall semester of 20 19, the textbook "Morality and Rule of Law, Chinese and History in Compulsory Education Stage (Primary School and Junior High School)" compiled by the Ministry of Education has been put into use all over the country. Therefore, almost all grades 1-9 use unified textbooks. In other disciplines, all localities are basically continuing the previously used textbook versions. The use of textbooks in primary and secondary schools should remain relatively stable, and textbook versions should not be changed at will. If it is really necessary to change the textbook version, it should be strictly implemented in accordance with the relevant provisions on the selection of textbooks for primary and secondary schools.
