As the winter coming in the northern hemisphere, the number of confirmed cases of COVID-19 has surged globally, a second wave of epidemics have appeared in some European countries, and sporadic and local outbreaks have occurred in parts of our country. It can be seen that the epidemic has not yet ended，so prevention and control cannot be taken carelessly. On the evening of October 19, 2020, the Youth League Branch of the Institute of Space Science and Applied Technology launched a group activity with the theme of "Scientific epidemic prevention, you and I come together" at L817.

The group activity kicked off in a loud anthem. Since the outbreak of the epidemic, the majority of young people have not been afraid of difficulties and have fought arduously with the epidemic, which demonstrates the sense of responsibility that contemporary youth have the courage to assume.

Then the class held a session of playing games to learn about epidemic prevention. The members of the branch said that they had deepened their understanding of epidemic prevention through this session. After that, the students watched a tribute video to the anti-epidemic countermarching people. The students felt the unity of all the people of our country and the sense of responsibility and mission of a great country during the war of epidemic prevention.

The last item of the event is the epidemic, I want to tell you. The students spoke enthusiastically, expressing their love for the motherland and yearning for the end of the epidemic and the restoration of a better life.

During this group day, the students learned in-depth knowledge of normalized epidemic prevention and control, and at the same time felt the strong cohesion of the Chinese people. We must cherish the hard-won results of the fight against the epidemic and normalize the prevention and control of the epidemic. We must start with ourselves, and China will surely defeat the epidemic.
