What material is good for filling missing corners?

Bronze is better for the corner-filling plaques

Nowadays, many missing-corner plaques are made of peach wood. The peach wood is used to ward off evil spirits, not to fill in the missing corners, because it is used to fill in the missing corners. It requires aura energy, and it is impossible to absorb energy if it is made of peach wood. Feng Shui pays attention to the combination of energy and hexagram positions. Feng Shui is about the aura effect. That is to say, when it comes to filling the missing corners, the main thing is to drive the aura effect on the hexagram umbrella, so as to achieve the purpose of filling the missing corners.
