At the centre of the mirror are two Chinese characters of double happiness, shuang xi, encircled by a ring, surrounded by five bats with heads facing towards these characters.There is a maker's mark within a rectangular frame at the bottom which reads 'geng tai he zuo', meaning 'made by geng tai he'.
When glass mirrors became common in the Qing dynasty, cast brass mirrors of this type were used as wedding gifts given to brides by their parents.
