China has passed a law on education aimed at reducing the pressure of excessive homework and intensive after-school learning.
Parents are required to ensure that their children have reasonable time for rest and exercise and do not spend too much time online.
In August China banned written exams for six- and seven-year-olds.
Officials warned at the time that the physical and mental health of the children was deteriorating, rtv21.tv reports.
In the last year, the state has introduced a series of measures aimed at reducing the "dependence" of children on the Internet and popular culture.
The latest measure was approved Saturday by the Standing Committee of the National People's Congress, the country's permanent legislative body.
Full details of the law have not yet been released, but media reports suggest it encourages parents to nurture their children’s morals, intellectual development and social habits.
The local government will be responsible for implementation, such as securing funding for "enrichment of extracurricular activities".21Media
