This study aims to understand the changes in Phase Ⅲ settlement of the Dazuzi site and examine its contemporaneity with other neighboring sites in southern Liaodung peninsula, based on the chronological sequence I developed in 2015. Despite the presence of carbonized crop grains including rice discovered in Phase Ⅲ settlement (1400- 1100 BC) it is assumed that the Dazuzi people had highly relied on hunting and gathering for food procurement. In addition, burnt and abandoned pottery shards found scattered on the floor are considered to be evidence of the house deconstruction rituals. In order to establish the chronological sequence among the sites, I proposed Phase
Ⅳ of the Shuangtuozi site and the temporal changes from Phase Ⅲ of the Dazuzi site to upper layer of the Yujiacun site, and then to Tuotou cultures, based on pottery typological seriation. It appears that the Shuangtuozi site was contemporaneous with Phase Ⅳ of the Datuozi site, which was later than Phase Ⅲ of the Dazuzi site. A settlement generally consists of clustered basic compositional units, household communities. Amongst the whole five stages of its occupancy, Phase Ⅲ-c is considered to have been the most transformative moment. In this phase, small rectangular houses were linearly arranged with the a large house at the center. Contrary to the previous phases with large and mid-size houses forming a majority of dwelling structures, a large number of small houses had been constructed since Phase Ⅲ-c whereas only one large house was built. At the same time, the frequency of house destruction rituals performed in each house also began to decrease and the ritual was practiced only in a single house per household community. The stone walls built in Phase Ⅲ-e is considered to have punctioned as a partition
separating small houses as well as defensive fortifications, which implies the commencement of a stratified society. Thus this can indicate major transition of the adjacent local settlements of the Dazuizi site.
