Corner trap, whether it is the door of a house or the door of a shop, is a corner trap if it faces a pointed or regular triangle object and looks like an arrow will rush past it. If this happens, never buy it, or it will bring bad luck. So when buying a house, you should look at the environment around the building.
As long as you meet a house with a corner, you must not buy it. A house with sharp corners or triangular parts is a very bad sign in geomantic omen. Living in it will feel unhealthy, and the health of yourself and your family will be affected, which will also disrupt your thinking. In addition, this kind of house cannot be rented or sold.
If you didn't know the harm of the corner-splitting demon before and bought this kind of house carelessly, you can only find a way to solve it. If you try to make the corner disappear, you can completely fill it with hollow bricks. If there is a corner obstacle between the window and the door, hang a gourd or five emperors' collection obstacle on it.
Corner blocking is actually very troublesome, so pay special attention to avoid this problem when buying a house.
