From the study and practice of self-created work, we can find that Neijia Boxing includes Tai Ji Chuan, Mind Boxing, Boxing Foot, Tongbei Boxing, Bagua Palm, Natural Boxing, Wing Chun Boxing and Italian Boxing. If you don't practice health qigong well, there will be confusion between yin and yang, evil spirits occupying the orifices, phlegm and blood stasis blocking the collaterals and other appendage situations.
