The mirrors in Feng Shui are different, such as the Eight Diagrams Mirror and the Concave-convex Mirror, but the mirrors in Feng Shui are used to block evil spirits. In geomantic omen, the placement and suspension of mirrors directly reflects the direction of blocking evil spirits, which can effectively prevent evil spirits. The dining table should be a place where families get together to eat. People need a relatively quiet and gentle atmosphere when eating. If decorative mirrors are placed opposite the dining table, it will destroy the comfortable atmosphere of the restaurant. Mirrors directly reflect the imposing manner in restaurants, bring people uneasy and complicated feelings, directly affect people's eating mood, and physical and mental unhappiness will indirectly affect their health. At the same time, the restaurant is also a place to gather wealth, and the mirror facing the dining table will directly destroy the wealth gathered in the restaurant, leading to the situation of family members leaking money. Facing the mirror of the dining table, the consequences are very bad, which should be avoided when decorating. If it has been renovated, the direct solution is to take the mirror to the dining table and hang it elsewhere to remove the harm caused by this taboo; In addition, if the mirror is fixed on the wall and cannot be detached, then the mirror can be blocked with cloth, so that the mirror can not be refracted and can be effectively blocked, thus solving this bad feng shui.
