It is precisely because the direction of due south is so noble that when people built houses in the past, no one dared to take the direction of due south of the meridian, both east and west, so as not to violate taboos and be convicted.
Originally, the principle of facing south is to have a correct understanding of natural phenomena, conform to heaven, gain the aura of mountains and rivers, benefit from the brilliance of the sun and the moon, care for the body and cultivate sentiment. Later, a feudal hierarchy of respecting the south and belittling the north was gradually formed.

Correct understanding of sitting north facing south
The view of house orientation is an ancient traditional building. 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.
In the house, facing the door, the direction you face at this time is the direction of the house. This is called "Xiang" and the position of the house is called "Left". Then the house facing south is the house facing north and the door facing south.
The ancients liked to sit in houses facing south, which was also related to the fact that most houses in ancient China were built in the form of quadrangles, in which the orientation of each house represented the position of the house.
Since the orientation of the house represents the position of the house, holding nature is a symbol of status. As a statue of the Ninth Five-Year Plan, no matter from the perspective of geomantic omen or status, there is no doubt that the place where you live must face south.
