What is the function of stone bucket geomantic omen?

The function is to turn the town house into evil. Since ancient times, China has a tradition of placing stones in towns and houses. Stone is a natural thing, suffering from the essence of the sun and the moon, and has considerable energy. If the old core behind the house with a backer is low-lying or has vents such as windows, it belongs to the pattern of air leakage in the house. You can put an imposing mountain stone here as a backer.
