What is the significance of Shanghai's initiative to reserve materials 14 days?

Shanghai issued some announcements, which really scared everyone. Preparing sufficient materials in advance is mainly to prevent the recurrence of the COVID-19 epidemic. In the past few months, some bad things did happen in Shanghai. Because of the epidemic, Shanghai residents can't go out for several months, and the local epidemic is more serious. However, in a closed situation, people are most worried about food. Even many people can't eat fresh fruits and vegetables during the closed period, and there have been some disputes, but they have all been solved in the end. However, once bitten, twice shy.

The purpose of this move is to remind everyone to pay attention to safety. Since Shanghai was unsealed, many people began to take revenge consumption. People who work will return to the company, but people who rest will do what they want, eat supper outside, eat all kinds of delicious food, and even travel frequently. If there are frequent personnel exchanges between provinces, some unexpected situations are likely to occur, so the opinions issued by various communities are also to remind everyone to reduce the time of going out and not to cause unnecessary trouble.

Mainly to prevent COVID-19 from invading again. After several mutations, COVID-19 became more and more contagious, and its symptoms were not obvious. If a person is a patient, the consequences are unimaginable. His body may not have too many symptoms, just like a potential bomb, which may be detonated at any time.

It is reported on the internet that Shanghai will implement closed management after the college entrance examination and senior high school entrance examination, so students will have a holiday and don't have to worry about academic problems. We don't know whether the news is true or not, but the relevant staff reminded us to make a good material reserve for 14 days, so it may be true. Therefore, local residents in Shanghai must not ignore the announcements issued by the community. It is best to prepare some fast food products and drinking water, and prepare more living materials to prevent problems before they happen.
