The goose-foot shape lamp, unearthed in 1992 from a burial complex of the Warring States Period to the Han Dynasty (475 BC-220 AD), is inscribed with "Yuling lady" on its base. Experts suggest it might have been a wedding gift. Known for their lifelong monogamy, geese symbolize fidelity and marital bliss in ancient bronze ware.
