東アジアの歴史と動態 It is common to look at the Chinese Han dynasty as being unified in every aspect. However according to some recent discoveries regarding Han political and financial systems in local and central authorities, it seems that this view is untenable. And what of Han culture?

This paper discusses these matters by looking at the carved images of long （龍）, or dragons on the stone reliefs of the Han dynasty. Through this study, the variations of the long carvings based on differing chronological periods and regions of the Han dynasty should become clearer.
