Why should you sit north and face south when buying a house?
Simply put, it is the function that meets people’s needs. Our country is a country in the northern hemisphere. Most areas are north of the Tropic of Cancer and face the sun. The dominant direction all year round is mostly southeasterly wind. Open the door to the light naturally, and face the cool breeze, which is very pleasant and comfortable. On the other hand, if the door (window) is open and there is a huge shadow of the building all day long, and the wind is blowing behind you, what will it feel like? You will soon feel depressed. This is why most buildings, especially residential buildings, face south. Nature that is in line with human nature is what architectural design pursues, because buildings are built for human needs.
The same is true for Feng Shui, with Suzaku in the front, Xuanwu in the back, Qinglong on the left, and White Tiger on the right. This kind of terrain hides wind and gathers energy. Wind here is understood to mean the dominant wind direction all year round, while Qi refers to essence and wealth. Having room here (that is, your home) is a great achievement. It can be seen that Feng Shui theory also meets people's needs to a certain extent.
