英文摘要:This thesis, based on 21 Ancestral Halls in Liu-Tui Area, attempts to probe into the formation of the Ancestral Halls during the Japanese Occupied Period (1895-1945). On the basis of the social background about the formation of Ancestral Halls and the status of Gong-Chang Organization, this thesis interprets the architectural characteristics of Ancestral Halls in Liu-Tui Area. From this study, we can realize that an ancestral hall was a building formed by the operation of Gong-Chang Organization and that the establishment of an ancestral hall was an index important enough for those who wanted to dwell in Taiwan. When an ancestral hall was built, the members of organizations, with attempts to make their offspring live better, always emphasized Feng-Shui, a knowledge to decide the siting of their ancestral halls. As one of the ritual architecture, the ancestral halls was an outcome of ritual system because more than a half of ancestral halls in Liu-Tui Area were integrated in the function of residence, the ancestral halls in Liu-Tui Area were used not only by all people in the clan and Gong-Chang, but also by the residents in the ancestral hall. Although the design of an ancestral hall was primarily considered for all members in the lineage, the residents who lived in ancestral halls used the ancestral halls mostly. Through the discussion Feng-Shui and the regulations of construction, we can understand that the residents and the builders in Liu-Tui Area regard the ancestral hall as a house for human being--yangzhai(陽宅). Gong-Chang, Ancestral Halls, people’s religious beliefes, and ways of using the ancestral halls represent the local characteristic of Liu-Tui Area. Besides strengthening their respect for ancestors, the establishment of the ancestral hall accomplishes the ultimate ideal for the lineage.
