 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. After the introduction of Buddhism, carved "funerary couches" featured similar scenes, now mostly religious. During the Han Dynasty, miniature ceramic models of buildings were often made to accompany the deceased in the graves; to them is owed much of what is known of ancient Chinese architecture. Later, during the Six Dynasties, sculptural miniatures depicting buildings, monuments, people and animals adorned the tops of the hunping funerary vessels. The outsides of tombs often featured monumental brick or stone-carved pillar-gates (que 闕); an example from 121 CE appears to be the earliest surviving Chinese architectural structure standing above ground. Tombs of the Tang Dynasty (618 – 907) are often rich in glazed pottery figurines of horses, servants and other subjects, whose forceful and free style is greatly admired today. The tomb art reached its peak in the Song and Jin periods; most spectacular tombs were built by rich commoners.
