The so-called "5+2" is a two-hour delayed service after class five days a week. Primary and secondary schools usually finish school around 5 pm, and parents usually get off work from 6 pm to 6: 30 pm. With this two-hour delay service, parents can get off work on time to pick up their children.

Children will be supervised by teachers at school. During this period, children can do homework, read books, play games and other activities without feeling lonely. They can also finish their homework carefully under the guidance of teachers, and parents don't have to worry about their children's safety all the time.
