Why do houses facing north and south have good feng shui?

I believe everyone has heard that this kind of house should choose a house with a good orientation. Houses facing north and south are more popular among friends, so what are the benefits of houses facing north and south? 1) Longevity: A north-south house not only has good lighting, but can also be protected from the wind. This is mentioned in the Feng Shui principles of a north-south house. Of course, its feng shui is not limited to these. In terms of Feng Shui, the north belongs to Yin, while the south belongs to Li, fire and light. In ancient times, there was a saying of governing by facing south; and according to our Chinese tradition, houses facing south are more conducive to longevity. 2) Good for the body. House Feng Shui focuses on storing wind and gathering Qi. Houses facing north and south just comply with the climate rules. In winter, the house can block the invasion of cold current, and in summer, it can welcome the southeast wind or southwest wind. The air flow in the room is smooth and cooler, which is good for the health of the residents. Houses with other orientations are easily hit by cold wind, which can easily lead to headaches, arthritis and other diseases. 3) Sufficient light. The sun rises in the east and sets in the west. Houses facing north and south receive the longest amount of light in a day. If there is sufficient light and the room is bright, it is not easy for the gloom to accumulate. The moon sets for a long time, so you can stay in the house in winter. The ultraviolet rays in the sun can also reduce the occurrence of diseases
