He’s lucky they didn’t beat him down
In the footage, shared on Youtube, the man can be seen moving on a tray with wheels, commonly used in China by beggars who have had their legs amputated.
Suddenly, a man comes from behind and pulls at the beggar’s trousers.
He struggles for some time as a crowd start to gather around the pair. Eventually the passerby manages to pull the man’s trousers down to reveal that the beggar has his legs tucked into his baggy underwear. The passerby shouts at the man in Mandarin calling him a cheat as the beggar uses his arms as his feet are stuck in his underpants, to slide away.
