Geng Shuai
Geng Shuai (), dubbed the China's Useless Edison, is a Chinese village craftsman whose fame has grown online because of his odd and often unnecessary inventions. A former welder, he became an internet sensation when he made videos of his creation and posted them online in 2017. He has since racked up more than 2.7 million followers on the Chinese short video app Kuaishou and almost a million followers on Weibo.
