Teenagers aged 6- 16 who are in good health and have no history of congenital or genetic diseases can participate. It is suggested that they can sign up for military summer camp, because children of this age are in the early, middle and early stages, and it is the best time to form good habits, whether in study or life. My child's first summer camp was a military summer camp signed up at the Shanghai Book Show Training Base, and there was still progress after one week. You can accept my suggestion and continue to ask questions if you don't understand.
