    On January 27th, in order to win the new pneumonia Resistance War (抗击新型肺炎战), the Ministry of Education issued a notice on putting off the start time of school in spring 2020. It was said that school should not start before February 17th. 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 children’s studies. It 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 learnt 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? Local education departments have also issued a notice, that is, to organize online teaching and create a network platform, where necessary courses will be shown every day, and online teaching will be given by excellent teachers of the subject, and students can learn at home through computer or mobile network.

It should be said that such a method is very good. It can not only keep students indoors and not worry about the infection 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; 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.
