After two years of experience, the custody industry has become a just-needed industry. At first, parents only chose the custody class because they didn't have time to pick up their children. But with the development of the trusteeship industry, it has become an irreplaceable industry for primary school students. Even if parents have time to pick up and drop off their children themselves, they should consider whether they have the ability to help their children with their homework. Even if you have the ability to help children with their homework, you should also consider whether children can integrate into the group. In the custody class, you can have more time to contact with children and make them better. Therefore, it is definitely profitable to stick to the custody industry.
