Children take up a free health check as part of a summer camp organized by a local company for the children of its migrant workers in Haining, east China's Zhejiang Province, July 20, 2019. Running for 40 days starting from mid-July, the summer camp invites 180 children whose parents work for the company away from home and thus offers them a chance for family reunion. Besides, the children can expect an enriched summer life here by taking academic, etiquette and sports courses given by university volunteer tutors. (Xinhua/Xu Yu)
