In order to survive in an extremely hostile environment, our primitive Chinese ancestors developed primary means of defense and attack that included leaping, tumbling and kicking. Although they knew how to fight with rudimentary weapons made from stones and wood, fighting with bare hands and fists became essential skills. The Martial Arts we recognize today as Kung Fu had their origins in the Shang and Zhou Dynasties (17 century - 256BC). During the following Qin (221 - 207BC) and Han (202BC - 220AD) Dynasties, wrestling, swordplay and spear skills became well developed and were popular among civilians and troops. Following the Song Dynasty (960 - 1279), various schools, boxing styles, movement sets and weapon skills flourished.
