Hong Xi Guan Fang Shi Yu Liu A Cai 1977

The film takes up the tale of Shaolin students Fong Si Yu and Hung Si Kwan (joined here by a third comrade, Lu Ka Chai) and their efforts to battle Ching oppressors. Their chief antagonist is the Abbot of Wutang who makes it his job to get rid of the three heroes and actually comes up with a clever plan to do so. He creates three exact doubles of the heroes and trains them to fight their counterparts.
