In fact, it is also the saying that the house faces south. As early as the primitive society, the ancestors built villages and tribes in a south-facing way, and most of the houses discovered by archaeology faced south. Some scholars in the Han dynasty suggested that choosing a city site should "combine the yin and yang, taste its spring and judge its suitability, which is the boundary between architecture and fields."
In other words, it is cloudy in the north, sunny in the south, cloudy in the north and sunny in the south, which is the requirement of site selection.
In fact, this has something to do with the geographical location of China, because China is located in the northern hemisphere, in the east of Eurasia, and most of the land is located in the north of the Tropic of Cancer, between temperate zone and subtropical zone. The sun shines from the south all the year round. The longer it shines to the south, the more sunshine it gets to the south, so the house facing south is easy to get sunshine, while the house facing the sun is good for heating.
In winter, the temperature of houses in the south will be one or two degrees higher than that in the north. More sunshine will help the human body absorb vitamin D and prevent rickets. More sun exposure can also sterilize and increase human immunity.

This is why people pay attention to the fact that the house faces south. Moreover, the back of the house is built on the back, and the gate faces south, which is also to avoid the dry and cold north wind. So now basically the living room and master bedroom of the house are facing south, otherwise the main lighting surface of the house is also on the south side.
