The whole world watches jokes about epidemic prevention in China.

At present, the schedule of the 2022 Beijing Winter Olympics is over half. At this Winter Olympics, many new technologies emerged, which attracted people's attention. Among them, the "foam epidemic prevention" of the Winter Olympics won international praise, which shows that China has achieved great success in epidemic prevention.

In order to prevent the import and spread of COVID-19 epidemic, at the beginning of the Winter Olympics, the relevant state departments directly conducted closed-loop management on athletes and other participants in the Winter Olympics, among which "foam epidemic prevention" was the most effective method. What is this "bubble"?

The "foam" under the Winter Olympics is not the foam produced by the shower gel we use when taking a bath, but a closed-loop system running at high speed. In this system, we have to touch things every day, such as competition venues, hotels, restaurants and so on. In this closed loop, people in the closed loop can't get in touch with ordinary people, so this effectively put an end to the spread of the epidemic.

The success of epidemic prevention in China can be seen from this Spring Festival. According to relevant media reports, during the Spring Festival holiday in 2022, the tourism revenue of 8 provinces in China has exceeded10 billion RMB, and 7 provinces have received more than 20 million tourists. These data show that in Chinese mainland, it is precisely because the epidemic situation has been effectively controlled that people have the idea of traveling, and under the influence of the Winter Olympics, the number of people who choose to go to the north-central region with abundant ice and snow resources has also increased.

Of course, in addition to the relevant epidemic prevention laws and regulations promulgated by the state, it is indispensable for Chinese people to attach importance to and consciously abide by the epidemic prevention policies, as well as their mobilization ability of unity and mutual assistance. At the same time, in order to end the epidemic in the world at an early date, China joined the "COVID-19 Vaccine Implementation Plan" and promised to give priority to providing vaccines to developing countries, including African countries, as global public goods after the vaccines were developed and put into use. China has demonstrated its commitment to the world.
