The former three Hans period is the time that formed characteristics of the Han society. Archaeological artifacts that represented this period are ring rimmed vessels, narrow bronze daggers, bronze mirrors etc., and they constitute a combibation of belongings of burials in wooden coffin tombs. These aspects can be definded as three Han’s wooden coffin tombs culture.
In order to derive the rank of three Han’s the wooden coffin tombs, I suggest standards 「A relative location of tombs」, 「Quantity of artifacts」, 「Quality and quantity of burials in prestage」in this paper.
The former three Han period is able to divide into twice phase, sixth steps by the combination of belongings of burials in wooden coffin tombs. As each step goes by, ranks of tombs can be derived 3→5→5→5→5→6 grades. However, it’s is still not to be equivalent at each step as the social hierarchy. I review the assumption of the uniqueness of Han’s social and cultural aspects at each step. First, the lowest class in society have no any tombs. Second, I do examines from a comparison between the tombs of the society showed the social aspects of each step. Third, it’s the area located the center of each chiefdom to locate the highest ranked tombs’s society.
Re-examined aspects of the evolution of social stratification, considering former assumptions, it’s subdivided with 3→4→4→3→3→3 classes in Han society, and it can be summarized as follows. In the 1Phase and Ⅰstep, emigrants from Liaodong peninsula are formed to the highest class in Han society, put a few representatives of indigenous peoples. In Ⅱ and Ⅲstep expanding the powers of the Han, a couple of middle managers to manage each community was responsible for trade and peninsula externally practices. In Ⅳstep, by increased the importance of trade, as the middle classes accumulated abilities stand face to face the highest classes in former step, they have moved Yeung-nam region, there are the center of social change. Starting Ⅳstep, the middle class of rulers in former phase changed the new highest rulers. this change, 「isolated tombs in the area scan be viewed」→「tombs gathered」, is samely associated with new emerging force that go up to the highest class in society, equipped with not political power nor economic power, led by practicality.
