In geomantic omen, stone rollers have the function of exorcising evil spirits and town houses. Putting it in the yard can resist external evil and ensure the stability of the house.
Stone mill is closely related to grain. Putting a stone mill in the yard can bless the good weather and abundant crops in the coming year and ensure the living standard of the family.
It is suggested to put the stone roller in the west of the yard, but it should be far away from home, so as to resist the evil outside. If there is a big tree outside the yard, you can put it under it, but you should also pay attention to stay away from the door at home, so as to protect the safety and health of the whole family. The role of the stone roll is to protect the safety of the town and represent the gods in the sky. Although leaning against the door can also play a corresponding role, the effect is not obvious, so avoid your own door.
