Now, except for the collective security personnel incident that suddenly broke out in Qingdao, after the basic security personnel incident broke out in other areas, Mr. Qing has adopted the method of all-staff nucleic acid testing, and all of them have been tested. It is impossible to let go of any case. So under this strict prevention and control, we can control it at all costs. For example, in February and March of the beginning of the year, we started the strict management system of closed communities and villages. It is under this system that we quickly returned to the economic state in the second half of the year.
In the second half of the year, our economy as a whole changed a lot, which was much better than that in the first half of the year, because many industries, such as the tertiary service industry, were the most affected, and the catering and entertainment industries could not open their doors, because no one could come from the village or work in the community. They can't start school casually, can't operate normally, and stay at home every day except for eating, so these industries have not developed, but after liberation in the second half of the year.
The number of people caused by epidemics in other countries is still expanding, but now we have a small-scale vaccine use, and it is said that it is hopeful to launch a large-scale vaccine by the end of this year. Now it is only used in local areas, and special medical personnel and special industries may use it. Although the scale is not large, we finally see hope, because victory is just around the corner, and we only need to persist for a few more months.
