What is double yin?

The ancients in China believed that everything in the world was in balance, and there was always yin and yang.

If for something, the proportion of yin is greater than that of yang, then we call it yin-yang imbalance and excessive yin.

In ancient times, people thought that everything could be linked with Yin-Yang and Five Elements.

For example, men are yang and women are yin; It belongs to Yang during the day and Yin at night; The sky belongs to yang and the earth belongs to yin; The mountain belongs to Yang, and the water belongs to Yin. Every year, every month, every moment is divided into yin and yang.

Then, if a woman gives birth to a baby girl in a low-lying place by the river on a cloudy night, we will call her (baby girl) Taiyin.

Too much yin now generally refers to things related to the yin world, that is, ghosts, bad orientation, wrong time and so on
