尚派形意拳系列－形意连环剑 Shang-Style Xingyi Quan Series: Xingyi Linked Sword (Chinese-English Edition DVD)
Li Hong/Xu H.L. (translated)
The application of Xingyi force and methods can be applied to the sword, but it is quite different from ordinary sword use. It requires the transfer of the hand's force into the sword; Thus it is said that the sword is the extension of the arm and can be brought into practice freely.
