What does the alternation of yin and yang in geomantic omen mean?

What do you mean by alternating yin and yang in Feng Shui? -there is an idiom called "jagged teeth", which can be used as an auxiliary reference to understand the staggered yin and yang. Yin and yang are intertwined, that is, yin and yang are closely connected and complicated, so it is difficult to distinguish them clearly. At the same time, there are mixed meanings of right and wrong. Give an indecent example to demonstrate, that is: men are yang and women are yin; When men and women are together, they are in close love and inseparable, and the result will be pregnancy. Roughly speaking, there will be three situations: first, it is possible to give birth to an emperor, who is either rich or expensive; Second, there may be a necrotic fetus; Third, everything is possible; This is the intersection of yin and yang.

Staggered yin and yang is a Chinese character, which means confusing yin and yang. Xu Linzhong's "Romance of the Gods" is back to the 35th time: "Master Wen's yin and yang staggered this time, and he was temporarily absent."

Second, the alternation of yin and yang in traditional Chinese medicine refers to the imbalance of the body.

Li Shimao-Yin and Yang crisscross: Shao Yin, half Yin and half Yang.

On shaoyang disease and clinical application of Xiaochaihu decoction; the representative prescription of shaoyang disease is Xiaochaihu decoction. My teachers Chen Shenwu and Hu Nv are both famous for their good use of Xiaochaihu decoction. But shaoyang disease and Xiaochaihu decoction syndrome have been controversial since ancient times.

Regarding the essence of Shaoyang disease, from Cheng Wuji to my teacher Liu Duzhou, it is said that Shaoyang disease is located in "half exterior and half interior", that is, between the sun and Yang Yang; Its nature belongs to "heat", which is a kind of heat syndrome with half exterior and half interior, forming the mainstream view of shaoyang disease. But I have been thinking about shaoyang disease and Xiaochaihu decoction for decades, and think that the essence of shaoyang disease is "half yin and half yang, or half deficiency and half excess", which is a pathological concept, not a concept of disease location, nor a simple heat syndrome. Because it is semi-yin and semi-yang in nature, its conduction and change have two ways: "cold and heat". The heat has both the sun and Yangming, or the three yang meet; Cold was introduced to Yin San. Specifically: 1. The original certificate of shaoyang disease, that is, Xiaochaihu decoction syndrome, is half yin and half yang, or half deficiency and half excess.

2. shaoyang disease, located at the junction of yin and yang, has two paths of cold and heat, and yang turns to heat, spreading three yang; Yang Qi's decline turns to cold, and the three yin are transmitted internally, so there are many syndromes and complicated changes.

3. The typical syndromes of Xiaochaihu decoction are three diseases of shaoyang disease, and four main symptoms of Xiaochaihu decoction plus seven diseases. Seven diseases are easy to diagnose, but atypical Xiaochaihu decoction syndrome is difficult to diagnose correctly.
