Why does the house face south?

Housing facing south is one of the architectural principles of traditional geomantic theory. Yi Xue believes that the south is lush and sunny, and it is supreme to be king facing south. The ancients thought that the north was yang and the south was yin, and the place with good feng shui should be harmonious between yin and yang. There are three reasons for choosing a house facing south: 1. Good lighting: According to House Classic, indoor lighting is better where the windows face south, southeast or southwest. Sitting facing south can make full use of sunlight, which is warm in winter and cool in summer. 2. Good ventilation: sitting facing south will make the air in the house fully circulate. 3. Avoid the north wind: Sitting facing south is not only for the lighting and ventilation of the house, but also to avoid the north wind. China is a country with monsoon climate. In winter, the Siberian cold current keeps invading, and in summer, the Pacific cool wind gradually rises, which makes the monsoon direction changeable all year round. Generally speaking, it is not an ideal choice for property buyers to sit in a southwest-northeast house. Because in addition to poor lighting conditions, it is easy to absorb moist substances in the air, which is harmful to human health. In fact, it is not easy to find the direction facing south, so it is ok to tilt slightly to the east or west by five to eight degrees based on the principle of due south.
