Sitting north facing south is a term used to describe the orientation of a house, that is, the house is located on the north side, the back of the house faces north, and the door opens on the south side. As early as the primitive society, our ancestors built village houses in the direction of sitting north facing south, and most of the houses discovered by archaeology faced south. Sitting facing south basically means that the main functional rooms (such as living room and master bedroom) of the house are facing south, or the main lighting surface of the house is on the south side.
As early as the primitive society, the ancestors of China built village houses facing south. In the Shang and Zhou Dynasties, the direction of measurement was the first step in choosing the environment. The poem Gongliu says: The scenery is just a hill, and its yin and yang are in harmony. Later, Chao, a politician in the Han Dynasty, suggested that when choosing a city site, it is necessary to "combine the yin and yang, taste its water spring and judge its suitability, which is the boundary between architecture and fields." In ancient times, it was cloudy in the north and sunny in the south. Residential sitting orientation is the saying of ancient traditional architecture. Most houses in China are built in the form of quadrangles, and the orientation of each house represents the position of the house. The following methods are used to judge the orientation of the house.
