First, it is a good thing to take precautions before they happen. However, we should consider that if a student is infected with COVID-19, it is undoubtedly a bomb, which will blow up a bunch of people. Therefore, the school should not only publicize in place, but also control all aspects more strictly, and don't let go of any dead angle. We should make all preparations, always be vigilant, and never be negligent, so as not to get out of control again.
Second, the world is still very unsafe. The influence of COVID-19, which has sailed for thousands of years, has thrown the rest of the world into chaos. It is the world hegemon, the United States, and there are millions of patients in their country. The country is out of control, and the number of patients is increasing exponentially every day, which is extremely dangerous. Moreover, all countries in the world are studying vaccines, and there is no news yet. For us China people, the safest place is our country, but we must always pay attention to it.
Thirdly, there are imported confirmed cases in all provinces of China, and there are problems in students' safety. As far as Jiangxi is concerned, there are as many as 5 confirmed cases in this province. Although he has been discharged from the hospital and there are no confirmed cases imported from abroad, Jiangxi is relatively safe at the moment, but there is a huge flow of people across provinces every day, fearing that one day someone will be infected with pneumonia and will panic again, and students will have a wide range of activities.
