Village groups are a common phenomenon in Huizhou Region, a historical region in eastern China where shared inter-village spaces play important roles in linking villages. This study analyzes the spatial layouts and characteristics of the inter-village space in the Hongguan village group in Wuyuan County, Jiangxi Province. A comprehensive literature review and the results of field research, qualitative analysis, and quantitative analysis prove that the regional spatial structure is maintained among inter-village space, landmarks, villagers, and villages within the village group. Through a summarized analysis of nine research slices, this study complements previous Huizhou Village studies. It provides valuable information for the preservation of traditional villages and reveals the hidden rules, potential order, and social meaning of inter-village spaces.
