Will the sky behind the house be harmful?

The gap between the two buildings is called "cutting the sky". For example, if the house is cutting against the sky, it is unlucky, because the sharp corners of the walls on both sides are cut head-on, which will affect the health and luck of people in the house. The fierceness depends on the distance of big cutting, and the closer it is, the fiercer it will be. Unless the distance exceeds 100 meters, it will not be affected, and it will be weakened by the fierce spirit. In addition, the longer the length of the chop, the stronger the ferocity, and it doesn't matter if you are behind the house.
