Just saw an article about a demonstration of an "Iron Crotch Qigong" demonstration in Luoyang. The master in question (Wei Yaobin) said he practices a style called Simian Bafang Tongbei - certainly from the pictures seems like a pretty tough martial art with emphasis on conditioning. Any RSFers know more about the art and if it is related to the other Tongbei styles?
