According to the creation theory derived from the I Ching: “Tai Chi gave birth to Liang Yi. Liang Yi gave birth to Ssu Hsiang. Ssu Hsiang gave birth to Pa Kua.” This is a high level form containing 81 movements, all of which are balanced in a manner which promotes the development of the entire body. Waist movement is emphasized even more, resulting in greater flexibility and martial potency. Qi Gong is also incorporated within it, massaging internal organs and thus fostering the development of energy and power.
