Gao Yisheng Style Bagua
The Gao style system is referred to as the Gao Yisheng branch of the Cheng Tinghua system of Baguazhang. Essentially, Gao Style Bagua is a unique subsystem. The Gao style system, because of Gao's own martial progression over time, can be found to have a number of different permutations, represented in these various lingages. All are valid examples of Gao style Bagua because they all represent Gao Yisheng’s progression as a martial artist. Gao was refining and creating sets until he died. He changed his straight line, pre-heaven and weapons sets more than once in his life but at its core it is a complete Baguazhang system.
Gao style explicitly divides training into two categories: pre-heaven (先天) and post-heaven (後天). Pre-heaven training includes walking the circle and practicing changing palms on the circle; this material is similar to that found in the other Cheng styles. Post-heaven training consists of 64 linear palms (六十四掌) said[by whom?] to be passed down by a man known as Song Yiren (宋益仁) (i.e., Song Yiren (送藝人), or "person who gives arts"); these palms are unique to the Gao system.
