Pushing iron hoops is a special memory of our children born in the 1980s. At that time, running barefoot and recklessly on the road seemed to be a paradise for us to play in all places, but I don't know how to find a place to play recklessly when I grow up. The scene in the video is downstairs of my community. It's usually busy at 9:00 p.m., but now I can't see people because of the epidemic. My friends and I play with impunity.
