What's the joke about grabbing vegetables in Shanghai?

Under the epidemic situation, it is an extravagant hope to have a vegetable field on the roof of your house, because people in the city live in tall buildings, and it is not easy to really have a place of their own. It may be that the residents on the fifth floor got some right to use the roof when they bought a house. Some people had the right to use the roof, but they didn't use it.

It is also possible to grow vegetables on the roof of a colleague's house, but it is also a very energy-consuming thing to transport seeds to collect soil and then carry out pest control and weeding every once in a while. Many people who live in the city think that there is no need to compete. The area is not large and they can't win much. Usually, it doesn't cost much to eat those fruits and vegetables directly in the vegetable market, but now there is an epidemic, which is different. Having your own vegetable field means that you can guarantee the most basic vegetable supply for your family.

There is a 10 square meter on the roof? In such a 10 square meter vegetable field, planting vegetables according to season can not completely guarantee the freedom of growing vegetables at home, but at least it will not really reach the point where there is nothing to eat. It can be used as an emergency, because some old people stay at home and retire. There is nothing to do. They like to grow some fruits and vegetables on the roof. After all, they are idle and looking for jobs to kill time. It didn't make sense at first, but it was boring. Now suddenly it's different.

After the epidemic, money can't buy vegetables or daily necessities. Now many places are closed, and you can only make an appointment in advance to buy food. And it may not be sent there, and it may not be possible to go out and get it. This is a problem, not only in one place, but in many parts of the country. So this matter should remind everyone that there is no harm in planting some vegetables in a free place. Although it cannot create much output value, it will be valuable when it is really needed.
