Preliminary Study on ‘Replication-Expression’ Mechanism of Traditional Hakka Walled Village Adapted to Region: A Case Study of Nanhua Village of the Qing Dynasty in Western Guangdong

Nanhua Village in Yangjiang, Guangdong Province, is one of the few large-scale traditional Hakka Walled Village of the Qing Dynasty preserved in western Guangdong. Through field research, the village was recorded in detail, and the spatial morphological characteristics of Nanhua Village were analyzed in aspects of historical background, axis rank and order, enclosure and centrality, integration of ancestral hall and living rooms, etc. In addition, spatial gene theory was also used to compare and refine how traditional Walled Village architecture adapted to the regional “replication-expression” mechanism. In order to provide auxiliary references for the excavation of traditional architectural spatial form organization and in-depth cognition of Hakka cultural connotation.
