Essential Series of Sha Guozheng's Xingyi and Bagua: Xingyi Mixture Boxing and Xingyi Eight-form Boxing : The traditional routine of Xingyi mixture boxing is formed on the basis of five-element boxing (wuxing quan) and twelve-style boxing. It combines the inner and outer energies and mixes hardness and softness to exhibit undulation and smartness. If you can master its techniques, you can improve your kungfu and grasp the essentials of xingyi quan. Xingyi eight-form boxing is grandeur and elegant, with complete force, spirit and shape, fast and agile moving. Move simultaneously with spirit, Qi, mind, force, hands, eyes, body and steps. It can be used for both attack and defense. Xingyi quan is one of the three major "internal" Chinese martial arts. The other two are Taiji quan and Baguazhang. Xingyi quan translates approximately to "Form/Intention Boxing", or "Shape/Will Boxing", and is characterized by aggressive, seemingly linear movements and explosive power. Its origins are traceable to the 18th century and may go back even further. There is no single organizational body governing the teaching of the art, and several variant styles exist. A Xingyi quan fighter uses efficient coordinated movements to generate bursts of power intended to overwhelm the opponent, simultaneously attacking and defending. Forms vary from school to school, but include barehanded sequences and versions of the same sequences with a variety of weapons. These sequences are based upon the movements and fighting behavior of a variety of animals. The training methods allow the student to progress through increasing difficulty in form sequences, timing and fighting strategy.
