Wine Yin is a concept in China's ancient theory of Yin-Yang and Five Elements, which originated from "the Qi of Three Yang, which runs endlessly in four seasons" in Zhouyi. In Zhouyi, "Yin" stands for flexibility, negative pole, darkness and silence, while "Yang" stands for rigidity, positive pole, light and noise. Wine yin refers to the negative attributes of brewed wine.

In ancient times, people had special worship and respect for wine, and wine yin was regarded as the mysterious power and soul contained in wine. It is believed that drinking alcohol yin can promote the balance of yin and yang in the body, enhance physical health and mental state, and is regarded as a way to preserve health and realize spiritual purification.

Liquor plays an important role in ancient culture, not only as a beverage, but also as a cultural symbol and artistic expression. In the works of ancient literati, poems about wine songs often appear, from which we can see the ancient people's love and admiration for wine songs. At the same time, drinking is also one of the essences of China's food culture, and it has become an important carrier of cultural exchange and inheritance.
