The Yang style taiji sword, as I was told, was the form that GM Liu Yunqiao taught which he received from General Zhang Xiangwu - It is an interesting form and relatively different from many of the current Yang style taiji sword forms - When I learned it there was also a Part B in which two persons went through the form thus illustrating applications - below is the exact form taught to students of Master Tony Yang.
