Why does our house face south and back north? Most people know that this is auspicious. Why do you say auspicious? Generally, Mr. Feng Shui will draw a compass to tell you a string of nouns of orientation that you don't understand, and then tell you that it is best to face south. Some gentlemen will sell you some inferior "green dragons" and "white tigers" ... as for the principle of facing south, they won't tell you, maybe they don't know the principle at all.
In fact, the reason is very simple. The simplest point is Chaoyang (China is in the northern hemisphere, and the most accurate point is facing the southeast). Generally, there is not much moisture in Chaoyang houses, so there are many fewer bacteria, because the ultraviolet rays of the sun have bactericidal effect. This is of great benefit to the health of babies and adults.
Secondly, in ancient times, people facing south were first awakened by the sun and then got up to work in the fields, always earlier than those facing north. In the farming era of more work and more income, with the accumulation of more time, wealth will gradually exceed that of people facing north. Of course, this is also probabilistic. Simply put, career is better than others. In modern society, the benefits of "facing south" are much less, but when you go out in sunny weather, your mood and spirit will be much better, which is another benefit.
Another function of "facing south and facing north" is "sheltering from the wind" Geographically, the terrain around the Central Plains is flat. Cold air from the north can run through China, and so can warm air from the sea. Therefore, there is a saying in geomantic omen that evil wind and positive wind prevail. Then people who live under the evil wind will naturally have a fortitude to resist adversity, but as we all know, the consequences of fortitude are either getting ahead or losing their reputation. For housing, stability is the most important, so soft sunshine is more suitable for people to live and work in peace and contentment.
