1. The stone mill is a folk agricultural tool invented by Lu Ban of Lu State, and its design is based on the concept of Yin and Yang, so there are two stone mills, one like the sun and the other like the moon. According to the theory of Yin-Yang and Five Elements, the stone mill represents the "white tiger" god in the house and respects the west.

2. Town house stone mill. There are many styles of stone mills, among which the larger cart-type stone mill, also known as the town house stone mill, is usually placed in the front yard of the house as an object to connect Feng Shui. The owner of the stone mill in the town house does have the implication of abundant financial resources and adequate food and clothing. In this regard, remember that you can't make the stone mill face the door, which will easily affect the circulation of Feng Shui, destroy wealth and form a rush. In addition, there will be no serious problems.

3, facing the white tiger position. Ordinary stone mills will be placed outside the house for convenience, but ordinary stone mills are more particular and cannot be placed casually. According to the positions of Yin and Yang and five elements of Zuo Qinglong and Right White Tiger, it is best to place the stone mill on the right side of the gate, that is, the position of the white tiger, without being blocked, which can better ward off evil spirits. If you put it in another position, it is likely to block the feng shui, which is not conducive to the fortune of the host family in the house.
