The mahogany pegs are engraved with the words "two fires and one wood" in the direction of yin, yang, eight diagrams and five elements, which are arranged on the ground at the door.

Peach is a combination of these two words, which means the omen of wood. Wood is the dragon of the east, the dragon of the west, the white tiger of the west, the disaster of the west, the fire in the fire, the ghost of the west, the evil fire in the south, and the dark and humid atmosphere in the north. This is what the whole explanation means.
