1, the back door opens to the cliff. If you open your back and look at it, if it is a ravine, downhill or cliff, it means that your back is not supported, just like a seat without a backrest, people are unstable and uncomfortable, and may accidentally fall backwards. In fact, the same is true when applied to houses. However, without the support of the gas field in the rear, wealth will be a thousand miles away, and it is difficult to work at home and make money. If the back door is a cliff or downhill, the children at home may open the back door, which may also cause life crisis.
2. The front door and the back door are in a straight line with the geomantic omen. If the front door and the back door are connected in a straight line, and there is nothing in the middle, it is easy to form the so-called "evil spirit". Such geomantic omen will have the opposite effect of discouraging and releasing wealth. Under normal circumstances, there are furniture or screens in the middle, which does not constitute evil spirits.
There is an alley behind it. In geomantic omen, if there is an alley and a road leading to the back door of one's home, such geomantic omen is unlucky, which will have a negative impact on one's family fortune and affect the owner's health, safety and wealth.
There is something behind you, so you should look at the right place. It is said that there is something behind it that is lucky. But sometimes it's important to depend on the place. If you live near the ridge, there may be a mountain at the back door of your house. Faced with this situation, even if there is something behind it, it is very dangerous.
