In the Yellow Emperor's Canon of Medicine, four qi tune the spirit: autumn and March, which is called capacity. The weather is urgent, the atmosphere is clear, you lie down early and get up early, having fun with chickens, so as to calm your mind, slow down the punishment in autumn, converge your spirit, calm the air in autumn and make your lungs clear. This autumn air should be a way to increase your income. On the contrary, it will hurt the lungs, have diarrhea in winter, and few people serve Tibet.
The three months of autumn are the season when everything is fruitful and mature. This season, the weather is fine, the wind is urgent, the vegetation is withered, and the earth is clear and clean. People should go to bed early and get up early, and work and rest with chickens at the same time. Make the mood stable and calm, thus buffering the influence of cold air in late autumn on people; The air that diverges outward before convergence makes the human body adapt to the breath of autumn and achieve mutual balance; Don't let your emotions leak out, so as to keep your lungs open. This is the law of conforming to the autumn spirit and maintaining the convergence function of the human body. Violation of this rule will hurt the lungs and will be discharged from the valley after birth in winter. The reason is that the convergence function of human body can not be properly maintained in autumn, which leads to insufficient closed storage in winter.
