What is evil?

The "pathogenic factors" mentioned in Chinese medicine include all kinds of pathogenic factors that can lead to human dysfunction and imbalance of internal and external environment. Such as wind, cold, summer heat, dampness, dryness, heat (fire), indigestion, phlegm and so on. For example, six evils, namely wind, cold, dampness, dryness and fire, also known as six qi, including pathogenic factors that cause infectious diseases, are exogenous pathogenic qi that causes exogenous diseases. Healthy qi is damaged, and evil spirits take advantage of it. So evil spirits are also called "evil spirits". Historical Records Biography of Bian Que and Cang Gong: "The spirit can't stop evil, and evil can't be vented. It is because the yang is slow and the yin is urgent that it suddenly dies. " Su Wen Xie Lun: "Fur first suffers from evil spirits." "Seven Signs of the Cloud" Volume 36: "All kinds of wind diseases can't lie down, and they can't move, so they suffer from evil." Huangdi's Neijing thought: the sick have yin or yang. Yang here refers to wind, rain, cold and heat, that is, abnormal climate between heaven and earth will cause human diseases. If the weather is evil and you are weak at this time, you will get sick, which is called evil. The so-called yin, in fact, is a three-point diet, unrestrained life, moody.
