Shan nan shui Bei feng shui
Of course, the experience of "mountain south and water north" is still limited. It is understood that in the ancient Yin-Yang geomantic omen in China, dryness was called "Yang" and dampness was called "Yin", that is, the place where the sun could shine was called "Yang", and vice versa.
The ancient political center of China was mainly near the Yellow River Basin, and most of its territory was located in the north of the Tropic of Cancer. Therefore, in the eyes of the ancients, the sunny slopes of most mountains in the territory are in the south, so it is called "the south of the mountain is the sun".
In addition, China's terrain ladder is generally "high in the west and low in the east", and most rivers in the territory flow from west to east. For a river flowing from west to east, due to the influence of geostrophic deflection, the south bank of the river is seriously eroded, and it is easy to form steep slopes, caves and other terrain, which makes it difficult for sunlight to shine and more humid. Moreover, if there is a mountain peak on the south bank of the river, it will also block the sunlight that originally hit the south bank, so it is called shade.
On the contrary, the sediment accumulation on the north bank of the river is mostly beaches, plains and other landforms, which are more easily exposed to the sun and appear drier, so it is called "clear water in the north".
