Why do single-family houses have to leave a back door?

There are many high-rise buildings now, because the high-rise houses are all rooms, so every household can gather air instead, and most of them have balconies in front and back, and there is no need for a back door. But when it comes to single-family houses, whether villas or bungalows, there must be a back door. As long as the front door doesn't lead directly to the back door, air circulation can be maintained, and residents will not be locked in cages without a second door just in case. However, the main reason is fortune. If there is no back door in a single-family house, the fortune of the residents inside will definitely stagnate and everything will go wrong.

Some houses are strange. As soon as you open the front door, you can see the back door immediately. Just as we can see through the back of a person's head when we look at his face, this kind of house is basically a big killer.

China's geomantic omen is about hiding wind and gathering qi. Where there is gas, there is luck and energy. A house with a front door leading to the back door must be filled with air before leaving. You can't hold your breath. If you live in this house for a long time, your health will go from bad to worse if you don't make money. As soon as the gas is released, the fortune is like a slide, getting worse every day.
