The Eight Masters(1976)

Shiao Chieh is left to a monastery when his family is killed, and grows up to be an incredible martial artist. He passes a gruelling and weird series of tests, most of which consist of being whacked by bronzemen, and goes out into the material world. He returns to live with his blind mother and his cousin, Ming Chu, who keeps being visited by an older dark stranger. Shiao Chien soon discovers Ming Chu is not really his cousin, but the niece of a man whose earnest wish is to see him die.
