 The Lei Cheng Uk Han Tomb Museum in Hong Kong displays a far humbler middle-class Han dynasty tomb, and the mid-2nd-century Wu Family tombs of Jiaxiang County, Shandong are the most important group of commoner tombs for funerary stones.The walls of both the offering and burial chambers of tombs of commoners from the Han period may be decorated with stone slabs carved or engraved in very low relief with crowded and varied scenes, which are now the main indication of the style of the lost palace frescoes of the period.A cheaper option was to use large clay tiles which were carved or impressed before firing.
