Ancient health care experts believed that "playing" and "qi" were two different concepts. Generally speaking, "Qi" refers to the original innate energy of the human body, and "Qi" refers to the energy generated through acquired breathing and diet. Qigong exercises mainly connect the innate "qi" through acquired breathing and other methods, so as to achieve the effect of strengthening the body and prolonging life. Practicing qigong can regulate yin and yang, harmonize qi and blood, dredge meridians, nourish qi, make people's lives flourish, and achieve the effects of strengthening the body, raising illness and prolonging life.
