What do you mean by delayed service?
Delayed service is a service launched by the school to alleviate the contradictions caused by parents' tutoring work and take care of some parents who work late.
Although the original intention of delayed service is to reduce the burden on parents, it can also give children more study time. But many parents worry that their children will be ignored by teachers if they don't go.
However, the delayed service itself is not suitable for everyone, mainly for some people whose parents are not highly educated, unable to help their children with their homework independently, or whose parents get off work late.
