During this period, the square-dancing grannies of Chaoyang dance team in Tangdong Street "transformed" into prevention and control propagandists, carrying the audio used in daily rehearsal every morning, playing the prevention and control knowledge of "new coronavirus infected pneumonia" in the streets according to the regional division, distributing propaganda materials for the passers-by, and reminding everyone to take protective measures at all times.

"We used to dance for our own health, now we publicize knowledge for everyone's health. I told the team members that we didn't dance at this time. We used our stereo to publicize the Party's policies and the knowledge of prevention and control of pneumonia caused by the new coronavirus. " Said Hu Xianglin, a citizen.
