Introduction to the bells of Huamen: In the center of the highest platform of Huamen, there is a "multi-tone square bell" hanging at the bottom of a 2-meter-high bronze flat-legged tripod. The bell is 1 meter high and 0.6 meters wide. It is made of bronze and has a square shape. When struck from all sides, it produces different sounds. There will be different sounds in different parts of the bell body. Climbing high to strike the bell brings joy and joy. The same bell sounds different sounds and resonates from all directions, which shows the loftiness and broadness of Hua Men.
