In ancient times, there were place names such as "Yin Shan" and "Heyang". Are mountains and rivers still divided into yin and yang?

The so-called "Yin Shan" and "Heyang" refer to geographical location. In ancient China, Shan Zhinan and the north of the water were called "Yang", that is, the place facing the sun;

The north of the mountain and the south of the water are called "shade", which means a cool place.

This theory is recorded in some ancient historical documents: "Twenty-eight years of public transfer" says that "the north water is Yang and the south mountain is Yang";

Xu Shen, a great scholar in the Eastern Han Dynasty, wrote "Shuo Wen Jie Zi", which also contains "Yin and Dark; South of the water, north of the mountain ";

In the Tang Dynasty, Li Jifu further pointed out in Yuanhe County Records: "The mountains are sunny in the south and cloudy in the north; The water in the north is sunny and the water in the south is cloudy. "

Place names with "Yin" or "Yang" reflect their geographical location.

Why did the ancients divide "Yin" and "Yang" in this way? This is because our country is in the northern hemisphere of the earth, and the sun we see shines from the south, so the south becomes the sunny side, and the north naturally becomes the shady side. The buildings we see in our life, especially the ancient buildings like the Forbidden City, generally face south, largely because the sunrise is for lighting.

So the south side of the mountain is sunny and sunny for a long time, so it is called "Yang". On the contrary, the north of the mountain is not easy to get sunshine, and the sunshine time is particularly short, so the north of the mountain is called "yin".

So, why is the water in the south called "Yin"? This is because water generally flows between two mountains, and the south side of the water is generally covered by mountains, and there is not much sunshine time, so the south side is called "Yin". On the contrary, the water in the north is called "Yang".

Summary: There are many place names in China that use "Yin" and "Yang" to indicate their positions! Cities ending in "Yang" are all in Shannan or Shuibei.

For example, Anyang, Xiangyang, Luoyang, Xianyang, Guiyang, Fenyang and Hanyang. Are all natural topographical states. Hanyang is a special one and the only city in China that ends with "Yang". This is not because the ancients used the wrong name, but because the Hanshui River was diverted and the location of Hanyang changed from north to south.
