The importance of rotating the waist

Body-movement and footwork, or "shen-fa" and "bu-fa" in Chinese, are very important in Taijiquan, but they are often neglected by many students. Incorrect body-movement and footwork not only affect combat efficiency but are also detrimental to health, causing disorders like knee injuries and back pain. Important principles like "differentiating yin-yang", "starting from the back leg" and "rotating the waist" ensure good body-movement and footwork.
