As soon as you enter the front door, you can see the back door. Although the two doors are relatively conducive to air circulation, the house also easily loses its thermal insulation effect, which is not good for the health of the occupants. From a Feng Shui perspective, this is a pattern in which the house cannot retain its energy and can easily leak money. The solution is to build a false wall in the middle of the house to block it, but do not use translucent materials, frosted matte surfaces or glass and other transparent materials. You can also use a cabinet to block it. The height of the blocker must exceed the size of the back door, so that the air can be completely blocked from escaping from the back door. If it is not convenient, you can also use a screen or curtain. If you have the conditions, you can buy a crystal cave and place it in the middle to gather wealth.
