It has a perforation so that it can be worn and is carved with inscription on both sides. One side is inscribed with the characters of the owner’s name,Liu fan, a member of the imperial Liu family. The other is inscribed with the characters Chen fang(Your servent fan), which identifies him as a state offficial of the Chu kingdom.
