It was said that school should not start before February 17. The exact start time of school will depend on situations and further notices.However, many parents are very worried that putting off the start of school may affect(影响）children's studies. If they have such a long winter vacation, children will not learn any knowledge read books or study at all. They may forget what they have learned before. Staying at home for a long time will make them keep eating, sleeping and playing, which seriously affect their physical and mental health .In short, the close of school influences learning and develops bad habits, so how should we avoid these problems?

It can not only keep students indoors and not worry about the infection(感染）of the disease, but also make them study at home, improve their learning ability , and truly achieve " no suspension of classes " . Both the platform itself and the recorded lesson resources are more useful , and are welcomed by parents and teachers .Of course, except for learning at home, it is also necessary to teach children about health knowledge, especially how to keep away from touching virus and other knowledge popularization; at the same time, it is also necessary for children to do some physical exercises or some games, which is good for physical health at home .55.
