Staggering footage has surfaced that shows a man practicing martial arts while standing on a moving motorcycle.
The video, which was captured by a shocked driver in the Chinese city of Chengdu, shows the man performing what looks like a tai chi routine in the middle of busy traffic.
Amazingly, the man manages to keep the bike steady as he practices his martial arts routine, and appears to be unfazed by his unorthodox training environment.
The man has apparently been dubbed the "Tai Chi brother" after the footage went viral online.
The incredible clip has been watched more than 3.3 million times on a single Chinese video-sharing platform
The Daily Mail reports that Chengdu police did not know the stunt had taken place, and hadn't received any complaints from other motorists.
However, now the video has gone viral, authorities have said they plan on issuing Tai Chi brother a 200 RMB (£23) fine for endangering public safety.
