I think it&;s better to have a winter vacation for middle school students, primary school students and young students this semester! Parents who return to school are really not at ease. Now is the most crucial time. The weather is cold and hot, so it is difficult for children to protect themselves, and they are prone to catch a cold. If they catch a cold, they still have to go back to school. For fear of missing their studies, it is easy to cause cross-infection. For the sake of parents&; peace of mind, let&;s take the winter vacation directly after online teaching.
