Is there a well in the ancestral grave at home?
From the perspective of geomantic omen, it is not good for manhole to be in any position of the yin house. If it is a lake, there are advantages and disadvantages depending on the orientation. But it can be cracked, and it will be fine if the wellhead is blocked with bricks. If you don't want to seal it, put a stone cover on the model to cover the mouth, open the cover when using it, and close the cover when using it. If the family is rich and powerful, you can dig a pond around the well, but the direction is best in the south and it is very fat ~ ~, but the pond is far from the ancestral grave, with at least 50 meters above it. Being too close is also a bad thing.
