The relic is a round perforated lid of a censer. It is named Bagua because it is decorated with Bagua (eight diagrams) patterns and flower patterns. The censer lid has a flat edge and a bamboo-hat-shaped button in the center for grasping the lid. The cover is engraved around the button with two circles of patterns: the inner circle is two groups of symmetrical hollowed-out flowers and plants, and the outer circle is hollowed out with Bagua patterns. The hollows allow for a flow of air. The censer is a combination of practical use and art, showing the ingenuity of the craftsmen.
