汉文帝
The tombs were made of large cypress planks. The outside of the tombs were layered with white clay and charcoal. White clay layering originated with Chu burials, while charcoal layering was practiced during the early western Han dynasty in the Changsha area. The tombs contained nested lacquered coffins, a Chu burial custom. The tombs also followed the burial practices dictated by Emperor Wen of Han, containing no jade or precious metals.
