Among the inherent types of martial arts in China, every martial arts has the function of fighting and keeping in good health, and almost every martial arts has its own boxing method, which is the expression of martial arts culture and also contains the excellent cultural connotation of the Chinese nation. Guxin Liuhe Boxing is also called "keeping the dust in the hole" at home. The attack of Heart Six-in-One Boxing requires that every hand and every style contain two meanings, that is, the eagle is in the sky and looks down from above; The bear is on the ground. Look down. The eagle advances and the bear retreats; The eagle is attacking and the bear is defending; Eagles fight, bears care. But from the perspective of health, every body, every hand and every movement contains yin and yang. Similarly, the eagle is yang and the bear is yin; Attack as yang and defend as yin; Fight for yang and care for yin. In short, this is the common name for the formation of the mind six-in-one boxing "eagle-bear wits"! Therefore, we also commonly call Heart Liuhe Boxing "the art of guarding points". This theory of yin and yang is guiding us, such as up and down, back and forth, left and right, advancing and retreating, caring for each other, fighting and defending. Otherwise, without this theory, it is impossible to practice psychological boxing well and psychological boxing culture will not exist.
