Three tombs of the Marquis of Dai family (
丞相利苍, his wife Xin Zhui
辛追, and their son), sealed around 168 BCE, were discovered beneath the Mawangdui hill in Changsha in the early 1970s. The finds revolutionized understanding of early Han life: the 2,100-year-old near-perfectly preserved body of Lady Xin Zhui, silk manuscripts of the Daodejing and Yijing predating standard editions, detailed medical texts, lacquerware, and a famous painted silk funerary banner. Now the signature holding of the Hunan Museum.
