Why is the direction of the house best facing south?

"Sitting north facing south" comes from Zhouyi, but it is not a geomantic theory and has nothing to do with the environment. In the Book of Changes, there is a saying that "saints listen to the world from the south and observe and govern the world from the Meiji world", which means that you mainly sit in the north facing south. This is based on gossip.

Housing facing south is one of the architectural principles of traditional geomantic theory. The ancients thought that the north was yin and the south was yang, and the place with good feng shui should be harmonious between yin and yang. As early as the primitive society, our ancestors built villages and houses facing south, and most of the ancient houses found today face south. Until modern times, the house facing south is still the first choice for home and house purchase. The reason for this is the following：

(1) Good lighting. "House Classics" says that indoor lighting is better where the windows face south, southeast or southwest. Sitting facing south can make full use of sunlight, which is warm in winter and cool in summer.

(2) Good ventilation. Sitting facing south will make the air in the room fully circulate.

Avoid the north wind. China is a country with monsoon climate. In winter, the Siberian cold current keeps attacking, so we should avoid the northwest wind.
