The 37 Forms of Tai Chi have today become synonymous with the Tai Chi of Professor Cheng Man Ching. Although Professor Cheng never referred to his Tai Chi in this way, but rather a shorter version of the Yang form, it has become a popular title to use. Some still use “Cheng Style Tai Chi”, a name first coined by my teacher Wu Kuo Chung but later copyrighted by others. Professor Cheng, however, would certainly not have approved of such a name.
Much mystery has surrounded the origin of the Zuo style of Tai Chi that was treasured by Professor Cheng Man Ching but little shared with his disciples. Master Wu Kuo Chung was passed down some of the secrets of this art by Professor Cheng in the final months of his life. His premature death, totally unexpected at the time, meant that he was probably unable to impart all his knowledge of the Zuo style.
