There is a grinding disc in the west of my house, but it is not needed. Bad for my house?

It won't make any difference. The millstone is a dragon, which can generally be placed on the left side of the whole house. I want to tell you something you'd better not have outside the mansion: the accumulation of debris outside the gate also has a great influence on Feng Shui. Some people like to put things or sundries that are not commonly used at the door, which makes the hall outside the already narrow door even narrower. Not only is it difficult to collect gas, but it may also lead to accidents on their heads. The door faces down the stairs, which belongs to the "roller shutter water" in Feng Shui, mainly because it is easy to leak money and air. The door faces the upward stairs in a sinister shape. When the slope goes straight into the house, it will affect the stability of the gas field in the house and easily lead to accidents. The door is facing the corner or wall, which will form a "sharp corner", which will not only affect the health and wealth of family members, but even form a mass annihilation. The door facing the elevator is a bad omen. At the same time, it is easy to be bloodied if you commit scissors, rush out of the door and fight. Money can't be saved at home, and conflicts are easy to occur at home.
