When friends get married, what's the use of this pyramid metal box and these two rotating rods?

These are the "treasures" of geomantic omen, one is called the pyramid (used to gather energy, and the open space in the tower can store things), and the other is called the dragon finder (used for exploration).

If you believe in feng shui, it has the purpose or significance of gathering energy and transporting energy; If you don't believe in Feng Shui, it has no specific meaning and can be used as an ordinary decorative piece.

Courtesy is light and affection is heavy.
