Baji (Baji Quan)八极
The term "Baji" refers to the attack methods of eight ("ba" in Chinese) body parts; they are head, shoulders, elbows, hands, buttocks, hips, knees, and feet, requiring a perfect performance of their functions when practicing Baji. Baiji denotes an extension of all directions, which means to let the ultimate snapping power go to the most remote. Baji uses six different kinds of starting techniques to break through the rival's defense and frames.
Baji has a long history. It originated in Qing Dynasty (1644-1912), and was created by the person named Zhang Yueshan. Because of dedication of all its successors, Baji has turned to a rich kungfu with its distinctive but simple style and methods which are related to ancient Chinese medicine, stating that all body parts are connected, either physically or spiritually.
Now Baji has a variety of forms, like Baji fist, Baji straight sword, Baji spear, Baji big broadsword, and Baji single broadsword.
In Baji, head and feet are equal to Qian (heaven) and Kun (earth). Shoulders,knees, elbows and hips stand for four directions. Every move demands a concentration of qi in the middle Dan Tian (an acupuncture point in Chinese medicine), and an integration of mind and will, will and qi, qi and force. Baji is noted by its direct and explosive power (it's called “Duan Da” in Chinese)coming from the heels of feet, which is swift, flexible, changeable and mysterious.
