Geomantic speaking, the back hill of the house is a large cemetery. What's the matter?

How far is it? If it is less than 30 meters, it is unlucky. This situation is difficult to do. If possible, build a wall behind the house. The wall should be semicircular, with the mouth facing outwards, which can block suffocation. If the conditions are not good, then build a small pyramid-shaped house (very small, probably not more than 1.5 meters) behind the house, with the door facing northwest, and put some fruit pulp rice as a memorial service on the fifteenth day of the first day.
