Taiji Quan (Tai Chi Chuan)
Taijiquan was originally a martial art. Fighters practiced standing positions to activate their Dantian (energy centre). Experienced fighters learned how to move this force beyond the limits of their body and used it to fight enemies, even at a distance. Today the focus of Taijiquan has shifted toward improving the health and treatment of illnesses. The applied forces are, however, the same as in the past.
Taijiwuxigong and Taijiquan are closely related. Dr. Shen Hongxun has based his system on postures and movements from the Taijiquan form. He took small parts of the form and instructed his students to repeat these, by which he discovered that repetition of movement creates spontaneous movement.
Taiji 37 is the Taijiquan system as taught by Dr. Shen. Taiji 37 and Taijiwuxigong use the same forces, but the approach is different. In Taiji 37 the Dantian force is accompanied by mental focus. Negative elements are expelled from the body by slow focused movements. In Taijiwuxigong negative elements are removed by spontaneous movement, which also eliminates energetic barriers.
