There are many different styles or families of Tai Chi Chuan. The five which are practiced most commonly today are the Yang, Chen, Wu , Sun, and Woo styles. All Tai Chi styles, however, are derived from the original Chen family style. Some people believe that Tai Chi was developed by a Taoist Priest from a temple in China's Wu Dong Mountains. It is said that he once observed a white crane preying on a snake, and mimiced their movements to create the unique Tai Chi martial art style.
