What is "mawangdui"

Mawangdui is an archaeological site located in Changsha, China. The site consists of two saddle-shaped hills and contained the tombs of three people from the western Han dynasty (206 BC – 9 AD): Marquis Li Cang, his wife, and a male believed to have been their son. The site was excavated from 1972 to 1974. Most of the artifacts from Mawangdui are displayed at the Hunan Provincial Museum. It was called "King Ma's Mound" because it was initially (erroneously) thought to be the tomb of Ma Yin (853–930), a ruler of the Chu kingdom during the Five Dynasties and Ten Kingdoms period.
