A palace lady under Emperor Yuan of Han (r. 49-33 BCE), she volunteered in 33 BCE to marry the Xiongnu chanyu Huhanye (
呼韩邪) to seal a peace alliance. Legend holds that the court painter Mao Yanshou (
毛延寿) deliberately uglified her portrait because she refused to bribe him, so the emperor only saw her true beauty on her departure day.
