Dai's Xinyiquan is a boxing style that conforms to the theory of traditional Chinese medicine and is based on Taoism, "Yin Yang and Five Elements" as the general principle, and the law of the five elements' generation, restraint and control. It educates people with the art of self-cultivation, which can not only strengthen the body, increase courage and bravery, but also make people understand the truth and practice the qualities of calmness and insight. It is a boxing created by our ancestors to open up wisdom. Dai's Xinyiquan is rich in content, mainly including seven Dantian exercises, health-preserving exercises, five-element boxing, four handles, gate positions, ten major forms, various cannon fists, various double handles, and six-in-one guns, Xinyi sticks, thirteen knives and other equipment. The main forms of expression are health-preserving exercises, routines and actual combat competitions. With "Dantian" as the core, the boxing manual says: Quietly nourish the spiritual roots and nourish the spirit, and cultivate the skills and the Tao to see the innocence. The longevity treasure is cultivated in Dantian, and ten thousand taels of gold are not given to others. Dai's Xinyiquan - both bare-handed and with weapons - every move and every form is centered on the Dantian. It is an internal power boxing that strengthens the body. The boxing manual says: After long practice, one will develop a Vajra body and all diseases will be cured, like a child.
