The tumulus was first discovered by school children who had found beads coming out of the hill. A policeman notified the authorities who began an excavation on the site.

A golden girdle found in the tomb is another important symbol of royalty and is only found in royal tombs. The girdle is about two meters in length, is made up of 39 plaques, and has various charms dangling from the main belt. The golden crown found in this tomb is also notable for its intricate open metal-work inner cap which suggests a symbolism with bird wings and shamanistic practices. A bronze tripod pouring vessel is possibly a Chinese import.
