This bronze mirror is well-preserved. It is 17.2cm in diameter and weighs 800g. It has a round button and plain edge.

A pattern is carved on the back of the mirror, showing the well-known folk story of Liu Yi, the princess's messenger. Longnv, the daughter of Dragon King of Dongting Lake, shepherded by the road. Longnv told LiuYi about her tragic life and asked him to deliver a letter. Liu Yi readily agreed and rode to the East as he bids farewell. This bronze mirror vividly engraved the beautiful romantic story.
