Clan Of The White Lotus (1980)
http://www.hkcinemagic.com/en/movie.asp?id=586 A remake of/sequel to the classic "Executioners From Shaolin". Lo Lieh plays the dastardly White Eyebrow monk Pai Mei, who--besides being able to achieve weightlessness, so he simply floats away from his attacker's blows--can suck his testicles into his abdomen! Out hero, played by "baldhead" Gordon Liu, receives a sound thrashing from Pai Mei early on, but later masters the graceful embroidery technique from kung fu babe Kara Hui. Needless to say, he finally gets his revenge when, after some spectacular fight scenes, he attacks Pai Mei's "vital spot".
