Every movement of Baduanjin is symmetrical and harmonious, which embodies the inner spirit, external comfort, the combination of reality and reality, and the combination of rigidity and softness. It requires practitioners to follow the shape, change shape at will, follow God, and integrate form and spirit. "Baduanjin" is a health care method that people have been paying attention to, and its sports theory is also reflected in Huangdi Neijing. Baduanjin, as a kind of health qigong, should pay attention to the heart in practice, so as to achieve the harmony between god and heart, heart and qi, and qi and strength, instead of deliberately emphasizing whether the shape of the action is in place. Seeking truth from facts in form is impossible in the end; Seek form by reality, not by itself. "Shake your head and wag your tail to get rid of your heart fire" in "Shu Ba Duan Jin". Literally, "wagging one's head and wagging one's tail" is the means, and "getting rid of one's heart fire" is the purpose. Then we want to know why "wagging one's head and wagging one's tail" can "dispel the heart fire". Traditional Chinese medicine said that "kidney governs water" and "heart governs fire", so we should use "kidney water" to extinguish the heart fire. If you want to put out the fire with water, you should water it from above. So the trick of this style is to keep the head as low as possible during the swing, the lower the better, at least lower than the kidneys.
