The origin of the name
Ping An buckle, a traditional round ornament, is only three or five centimeters in diameter, but it has been given the simple and simple meaning of "peace". Perhaps because there is no complicated carving, the surface is smooth and the shape is like a button, so it is named. We don't know when it first appeared, but it is more common after the Ming and Qing Dynasties, mostly folk ornaments. Its shape and inheritance have not changed much so far.
