On August 22, in Yongzhou, Hunan, a citizen photographed four grandparents using bike sharing as fitness equipment. In the video, four elderly people ride on City shared bicycles with piles on the side of the road, pedaling and idling. Some netizens commented: it will kill two birds with one stone if you can generate electricity. More netizens question this: “this is not good. Is this intentional destruction of property?” What’s your opinion?
