BANZAI7 NEWS--Entertainer Lo Wung, 42, taught the group of monkeys some basic taekwondo moves to entertain shopping centre crowds.
But when Wung took a tumble one of his pack turned and decked him with a kung-fu kick to the head.
The turncoat gang then swarmed all over their master — with one even grabbing his stick and cracking him over the head with it.
Hu Luang, 32, who snapped pictures of the big brawl in Nshi, in eastern China's Hubei province, said: "I saw one punch him in the eye - he grabbed another by the ear and it responded by grabbing his nose.
"They were leaping and jumping all over the place - it was better than a Bruce Lee film."
Wung only managed to get the monkeys under control by tangling them up in the rope that had been used to stop them running off.
Mr Luang said: "He was really furious, he made the monkeys kneel on the ground with their hands tied behind their backs to punish them and make them show remorse for their nasty attack."
Angry American TKD Monkeys are training for a rematch.
