Reverse Geomancy: The Spatial Patterns Between Jimei Ancestral Halls and Their Surrounding Environment

This study investigates the spatial relationship patterns centered around ancestral halls in villages in Jimei, China. Using a "reverse geomancy " approach, the study records the polar coordinates and orientations of 45 ancestral halls and their surrounding key elements such as feng-shui ponds, groves, drama stages, etc. to analyze the spatial distribution patterns of critical elements within the villages. The findings reveal verifiable spatial patterns in Jimei villages, some patterns such as the orientation of ancestral halls and the placement of feng-shui ponds, are related to traditional geomancy principles, while others are influenced by social needs and the built environment. Through statistical analysis across time, the study uncovers the historical logic of village construction and the ways feng shui principles have been integrated in Jimei. It emphasizes the importance of preserving the overall spatial patterns of villages, offers protection recommendations for elements like ponds and groves, and highlights the broad applicability of the research method to other settlement studies.
