This is baguazhang as done by famous Beijing expert Gao Ji-wu (高继武). His baguazhang uses YinFu’s material as a base and has influences from Li and Liang styles, plus a little xingyi and shaolin thrown into the mix. For more information on him, please visit (Chinese)
BTW, this demo looks a little rushed. His performance on his VCDs is much better. Enjoy.
