The Huizhou architectural tradition that defines Wuyuan's villages developed during the Song dynasty and reached its highest expression in the Ming and Qing periods when Huizhou merchants accumulated extraordinary wealth through trade in timber, tea, paper, and ink. The merchant families invested their profits in elaborate ancestral halls, family compounds, and village public buildings — all built in the distinctive style of whitewashed walls, dark tile, elaborate carved woodwork, and interior sky-well courtyards open to the sky.
Understanding the architecture as the product of specific social and economic circumstances makes the villages considerably more interesting than treating them as scenic backdrops. The spatial organization of the buildings — interior courtyard facing a small opening to the sky, main hall oriented for ancestral veneration, private quarters separated from commercial spaces — reflects a Confucian social order expressed in brick and timber. The village of Yancun has some of the best interior examples in the region.
