No. In accordance with the Constitution of People's Republic of China (PRC), the Law on Regional National Autonomy in People's Republic of China (PRC), the Education Law of the People's Republic of China and other relevant laws, we will promote the spoken and written languages of ethnic minorities in ethnic minority areas, and at the same time adhere to the principle of equality of spoken and written languages of all ethnic groups, and guarantee the freedom of ethnic minorities to use and develop their own spoken and written languages according to law. The implementation of unified teaching materials in minority areas is not to prevent the learning of national languages, and there is no contradiction between national languages and unified teaching materials. The unified compilation of textbooks for the three subjects will not affect the curriculum of other subjects in schools where minority languages are used as teaching materials, the teaching language and the existing bilingual education system will remain unchanged.
