Is there a grindstone in the gable behind the house?

There is a millstone on the gable behind the house. It's good. Because there is a grindstone on the gable behind the house, it can town the house. The stone can absorb the negative energy of evil spirits and suffocation in the living environment, and play the role of exorcising evil spirits, strengthening the body and town the house. The grindstone is just a general term, not a stone, but any abrasive tool with grinding ability, such as a diamond grindstone. When sharpening a knife, the right hand holds the handle tightly, and the fingers of the left hand gently hold the knife surface and move it clockwise. The surface of the millstone should be kept wet. Keep a stable angle between the knife surface and the grindstone surface, and the stone chips on the knife surface will prompt you for the corresponding angle. When pulling back the knife surface, don't use force on the fingers of your left hand, which is easy to cause back injury. When sharpening a knife, gradually reducing the pressure will make the blade fine and sharp, and the other side should also be ground clockwise (be careful not to hurt your hand).
