Lung men bei chi

This was one of the first movie, that i watched on video in the early 80´s, What i remembered was a lot of Kung-fu action, and pretty good acting, in that time the over the top sound effects when they were fighting was very disappointing, but still i remember one scene that was pretty strong, that was the snake torture, a woman tied to a bed having a snake that rattles between her legs. I think this movie is hard to get your hands on, but i still think it´s worth to watch. My rating is 6 out of 10
