Zhang Sanfeng
Despite the common belief that the "Nine Yang Manual" has Buddhist origins, Zhang Sanfeng begins to doubt this claim as he delves further into the text. He notices that the principles and philosophy of the skills depicted in the manual are very much Taoist in nature. He also points out that the manual was written in Chinese instead of Sanskrit, the language that the manual's alleged creator Bodhidharma would have used. Zhang develops the Taiji Fist based on the principles in the book.
