The "National Smart Education Platform for Primary and Secondary Schools" was upgraded on the basis of the original "National Network Cloud Platform for Primary and Secondary Schools". The new platform further enriches the original special education and curriculum teaching resources, and adds four types of resources, including after-school service, teacher training, family education and practical experience in teaching reform, with a total of six sections, which further highlights the need to serve the "double reduction" work.
