A jade burial suit () is a ceremonial suit made of pieces of jade in which royal members in Han dynasty China were buried. Structure Of the jade suits that have been found, the pieces of jade are mostly square or rectangular in shape, though triangular, trapezoid and rhomboid plaques have also been found. Plaques are often joined by means of wire, threaded through small holes drilled near the corners of each piece. The composition of the wire varies, and several suits have been found joined with either gold or silver. Other suits, such as that of King Zhao Mo, were joined using silk thread, or silk ribbon that overlapped the edges of the plaques. In some instances, additional pieces of jade have been found beneath the head covering, including shaped plaques to cover the eyes, and plugs to fit the ears and nose.

Considering the vast size of the country, and the relatively slow means of disseminating information, it is not surprising that the materials and techniques used in a jade burial suit occasionally differed from the official guidelines. A jade burial suit was extremely expensive to create, and only wealthy aristocrats could afford to be buried in them. Additionally, the process of manufacturing a suit was labor-intensive and is estimated to have required several years to complete a single suit. History Tombs from the Spring and Autumn period belonging to the dukes of the Jin state in Quwo were discovered in which the body was covered with small jade pieces once interwoven with silk. For many years, many archaeologists suspected that records of jade burial suits were only legends. The discovery in 1968 of two complete jade suits in the tombs of Liu Sheng and Dou Wan in Mancheng, Hebei, finally proved their existence. The jade suits of Liu Sheng and Dou Wan consisted of 2,498 plates of solid jade connected with two
