The Tangka of the Jiulong River in Zhangzhou have developed a cultural distinctiveness that sets them apart from land-based societies through long-term social division of labor, daily work, and changes in regional traditions. In certain areas, they have preserved their original way of life,serving as "living fossils" of aquatic society and reflecting the cultural diversity of the Jiulong River Basin. This study selects the only remaining Tangka's boat temple in Zhangzhou, Jinfa Temple, as an investigation point. Guided by theories from architecture, anthropology, and folklore studies, and employing methods such as literature collection, fieldwork, on-site surveys, and comparative analysis, this research aims to examine how the Tangka, after settling on land, effectively utilize the space of the Jinfa Temple boat temple and its surrounding area to maintain their original group relationships. It also explores how they reinforce collective consciousness and reconstruct group identity through rituals like the Wangchuan ceremony. Additionally, the study describes this unique cultural landscape and discusses the folk wisdom and spatial strategies involved in this context.
