Ancient health care experts believed that "playing" and "qi" were two different concepts. Generally speaking, "communication" is the initial 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.
Generally speaking, Qigong can be divided into nourishing qi and refining qi. Nourishing qi is a kind of meditation in Taoism, which transports the qi of Tian Dan together and makes it stick together to prevent it from being induced by the external scenery. Gas refining is mainly based on operation. If the boxer wants to use his arm strength when practicing boxing, he will send gas to his arm; There is strength in the waist, and qi is transported to the waist; If all limbs exert force, qi will be transported to the whole body.
