On 17 February, children of women’s football society of Chengnan experimental primary school, Hai’an were practicing football in after class service time. In the beginning of the new semester, ‘double reduction’ policy is implemented in our city and after class service work is promoted. Primary and secondary students use after class time to do sports, exercise, to improve volitional quality, and promote mental and physical health integrated development. Photo by Zhai Huiyong
