In ancient and modern geomantic books, the traditional geomantic theory really emphasizes that houses should face south. This is because China is located in the northern hemisphere of the earth, in the east of Eurasia, and most of the land is located in the north of the Tropic of Cancer. The sunshine mainly enters from the south all the year round, so the house facing south is convenient for sunbathing.
The balcony facing south is sunny, and the sunshine has the following benefits:
First, it can provide heating, and the temperature in the south is 1-2 degrees higher than that in the north in winter;
The second is to participate in the synthesis of human vitamins. Children who often bask in the sun can prevent rickets.
Third, the ultraviolet component in sunlight can kill harmful bacteria in the air. In particular, it has bactericidal effect on respiratory diseases and germs, and fourth, it can increase human immune function.
