Excuse me! Hanging Eight Diagrams Mirror, concave mirror or Convex Mirror?

The convex mirror of Bagua mirror and concave mirror have different functions. Concave mirror is used to collect evil spirits, and convex mirror is used to block evil spirits.

As long as it is clear what kind of evil is to be resolved, it is enough to choose the right mirror. If you are afraid that the one-sided mirror is not strong enough, you can use other methods to enhance the Eight Diagrams mirror's ability to resolve evil spirits, such as resolving fire evils such as chimneys. You can add cow symbols or cow-shaped ceramic ornaments behind the mirror to enhance the Eight Diagrams mirror's ability to resolve fire evils.
