Because the teaching materials and teaching standards are constantly changing, the national network cloud platform for primary and secondary school students will delete some backward and outdated courses in order to adapt to the changes and ensure the quality of uploaded courses.

During the epidemic prevention in 2020, according to the Notice of the General Office of the Ministry of Education and the General Office of the Ministry of Industry and Information Technology on the Work Arrangement of "Suspension of Classes and Non-stop Learning" in primary and secondary schools, the national network cloud platform for primary and secondary schools was released. In order to support the work of "stopping classes without stopping studying" and help students study at home, the Ministry of Education has integrated high-quality teaching resources of the country, relevant provinces and cities and schools, and opened the cloud platform during the school extension period.
