It is emphasized that keeping in good health with qi is an important aspect of Taoist way of keeping in good health, which can be summarized as the following aspects: nourishing vitality is the foundation of life. People should pursue something, not expect it. If you can't expect it, it will hurt your health. People should seek what they can get, give up what they can't get and cultivate their vitality with peace of mind. Quiet ventilation If you can keep your brain quiet for half an hour or an hour every day, you can give full play to the potential of brain cells, coordinate physiology and emotions, and reduce the consumption of heat energy. The quietness of the brain makes the muscles of the whole body easy to relax, and the blood is smooth, reaching the realm of "peace of mind, getting older and stronger". Calmly think that lust is directly related to internal organs, excessive anger hurts lung congestion, excessive euphoria leads to excessive dissipation of qi and blood, and thinking is too weak for the spleen and stomach. Calm mind can balance yin and yang, harmonize six veins, eliminate diseases and prolong life. Expanding stomach and nourishing qi Human beings rely on digestion and absorption of nutrients by the stomach and intestines, and it is very important to expand stomach and nourish qi. Excessive diet, alcohol and tobacco will lead to insufficient stomach qi and insufficient qi and blood. Whistling can relieve qi and stimulate the nose, throat, chest and abdomen. After dinner, taking a walk, humming your favorite poems, or humming a ditty can relax your mood, get rid of other thoughts and achieve ecstasy.
