Six o'clock. According to the inquiry of Chengdu Education Bureau, in 2023, Chengdu Xingzhi Kindergarten will start the delayed service until 6 o'clock at the latest. Children can stay in the park until 6: 00 pm after school at 4: 30 pm. Considering the practical problems involving the number of children and the allocation of teachers, kindergartens adopt the mode of mixed class trusteeship. After school, these children who need to be cared for are arranged in a class, which is taken care of by a delayed class care group composed of kindergarten directors, heads of all grades, kindergarten teachers, nurses and security personnel.
