China is located in the middle and low latitudes of the northern hemisphere. If the house is built in a place facing south, it can get more sunshine in winter and block the invasion of the north wind, while it can enjoy cool air in summer, which is very beneficial to the family environment without air conditioning, so they will pay attention to building a house facing south, which is more popular now.
Now the house has changed from the previous bungalow to the current unit building, and the population density has also increased, but many people still regard it as the basic requirement for buying a house. Because this kind of house has good daylight during the day, and there is no need to turn on the lights at home, I feel that the whole house is healthy and sunny. But if it is a backlit house, it feels gloomy and uncomfortable all day, so the ancients still paid more attention to building houses. The great wisdom of the ancients is that people can continue to learn now.
Because information technology and cities follow the village, everyone lives in the same village, so when building a house, everyone follows the requirements handed down from the village for a hundred years. In fact, you can not obey this, but you should know how terrible people are. Everyone in the village knows each other. If you are independent, you will be laughed at by the public. So, is there such a big pressure of public opinion? After all, it is very unnecessary to be laughed at by such things every day, because typhoons are made in the sky and underground. Therefore, in the long run, such an unwritten rule has been formed, but whether from the perspective of geomantic omen or tradition, it is better to sit facing south.
