Qigong is a set of skills or knowledge that adjusts breathing, body movements, and consciousness as exercise methods. The form of breathing, such as length, depth, body movements, and mentality, will all produce energy with different functions. Qigong conceives that qi exists between the heaven and the earth and all natural beings, and energy is always generated between the movements of exhaling and inhaling. The principle of qigong treatment is to master the method of regulating qi and blood, and to efficiently adopt the positive energy of the universe. By discharging the negative energy within the body, our body will repair itself and return to the status closest to the time of birth.
