Five Winds Tai Chi Chuan, as taught by Sifu Ian Cameron, is a form of Tai Chi derived from the style originating with the Wu family. The following description of the lineage is taken from the preface to Sifu Cameron's book. Sifu Cheng Tin Hung's Tai Chi Chuan is descended from the lineage of Yang Lu Chan and through his second son, Yang Pan Hau. Wu Chan Yu, a Manchurian, was taught by both these masters. This was the beginning of the Wu family lineage. Wu Chien Chuan, son of Wu Chan Yu, is recognised as the founder of the Wu style of Tai Chi Chuan. This style is second only to the Yang style in popularity. Cheng Win Kwong was a student of Wu Chien Chuan and, in turn, passed his art on to his nephew, Cheng Tin Hung. Cheng Tin Hung had another teacher, a Buddhist by the name of Chai Man Hun, who was a very strict master - so strict that he lost many of his students. At one time Cheng Tin Hung was his only remaining student. This master was responsible for Cheng Tin Hung's deepening understanding of the theoretical and fighting aspects of Tai Chi Chuan. Today the Tai Chi Chuan passed on by Cheng Tin Hung is named Wudang Tai Chi Chuan. This is simply named after the mountain range where the founder, Chang San Feng, lived. And from the foreword to the book, by John Burns: Ian Cameron learned Tai Chi from Sifu Cheng Tin Hung in Hong Kong in the early 1970s. Since that time he has been one of the most important figures in British Tai Chi, making sure that the Tai Chi that is passed on to his students is the genuine article, imbued with the spirit of the art as he learned it.
