What is "tongbeiquan"

Tongbeiquan (通背拳 tōngbèiquán; literally "Spreading Power from the Back Boxing", as tong means "through," bei means "back" and quan means "fist") is a school of martial arts popular in northern China. Tongbeiquan's basic precepts are Taoist in nature and many of the training methods in Tongbeiquan are similar to those of the internal styles. In traditional Tongbeiquan training, several parts are included: basic training (stance, arm techniques, leg techniques and conditioning), combinations, forms training, two-person free sparring, weapons training, and qigong training.
