What does the stone mill under the bed mean in geomantic omen?

Stone mill is a white tiger star. Usually the owner of the house is right, but the white tiger star. Basically, the loss of money is certain. The rural mills are all in the west wing or kitchen. The unused mill must be next to the toilet, the pigsty and the back edge of the house. The reason is to suppress the white tiger. In the past, there was a saying in the stone mill that there was a legend of exorcism, but the placement was very particular, and it was absolutely impossible to put it casually. But also has disadvantages when benefiting. There is a stone mill under the bed. It's not that the victim is confused by the fox demon, which is physically and mentally unfavorable and needs white tiger star to solve it. I just don't want to say anything.
