Legal analysis: the policy of double burden reduction for primary and secondary school students means: 1, reducing the workload of primary and secondary school students, and the policy requires reducing the workload and duration of students' homework. It requires reasonable regulation and design of the structure of homework, so that children can finish their homework as much as possible at school, and they can't assign homework to their parents, nor can they correct their homework themselves. 2. Reduce the burden of off-campus training for primary and secondary school students.

Legal basis: Article 33 of the Law of People's Republic of China (PRC) on the Protection of Minors, schools should cooperate with the parents or other guardians of underage students to reasonably arrange their study time and ensure their time for rest, entertainment and physical exercise. Schools shall not occupy national statutory holidays, rest days and winter and summer vacations, and organize underage students in compulsory education to make up lessons collectively to increase their learning burden. Kindergartens and off-campus training institutions shall not conduct primary school curriculum education for preschool minors.
