The family cemetery of Zhang Anshi was the first cemetery for nobles to be discovered in which the tomb occupants, dating, and gravesite orientation was so clear to investigators. As such, the site is of enormous historical significance. This essay introduces the entire site to readers and extrapolates aspects of the Western Han mourning regulations from the evidence presented by the jade suits, carriage and horse sets, tomb figurines, shrine, and layout. The essay also assesses scholarly debates concerning the degree to which Zhang Anshi's burial conforms to standards of late Western Han, and the relationship between Emperor Xuan's burial site and Duling with the site of Zhang Anshi's own tomb, questioning the traditional beliefs about “accompanying burials.”
