In Jintang County, Sichuan, archaeologists excavated 219 tombs that date from the late Eastern Han through the Six Dynasties. The majority date to the Western and Eastern Jin. Most of the tombs are small or medium size. Usually the tombs are grouped two or three together, which probably mean each group belongs to an individual family. An interesting grave good is a glass earring. Since Sichuan doesn't produce glass it had to come from somewhere else. Perhaps it was a good that came by way of the Maritime Silk Road.
