The exotic bone strikes of YSB Phoenix System descends from the era of Cotton Armor in feudal dynasties. The composite armor is cotton lined with iron or hardened leather. The cotton-lined steel sheets protect the torso, the arms and back of the hands- which provides a very strong, heavy, and dominant surface to strike with during close-quarters melee. Jet Li demonstrates the bone strike in the Warlords motion picture, a battle scene amidst the Taiping Rebellion.
