(2) Parents or guardians have the obligation to make school-age children or ward go to school;

(3) The whole society has the obligation to eliminate all kinds of adverse effects and obstacles on the education of school-age children and adolescents. Therefore, compulsory education needs the protection of the state, family and society. For the educated, this is both a right and an obligation.
