The coffin of Zeng Hou Yi consists of two pieces. This inner coffin has cambered surface and the inside appears to be rectangular. The complicated decoration has a red lacquer base and the patterns are painted with black, yellow and gold pigment.
On both sides of the coffin are window-like patterns and warriors with horns on head and halberds in hand. They are surrounded by complicated paintings of dragons, snakes, birds, beasts and spirits. The warriors are looking around the coffin chamber, guarding the soul that is supposed to sleep in the coffin.
