Traditional buildings are a comprehensive manifestation of history, art, and architectural features, and are also a carrier of folk culture, traditional skills, and regional aesthetic tastes. This paper studies traditional buildings and arts from three regions of Jiangxi, including northern Jiangxi, southern Jiangxi, and central Jiangxi. Traditional buildings in Jiangxi Province flourished in the Ming and Qing Dynasties. As Jiangxi is located in the interior of China and is adjacent to many provinces, the architectural art of traditional buildings is greatly influenced by geographical location. Traditional buildings in northern Jiangxi are influenced by Huizhou architectural culture, while those in southern Jiangxi are influenced by Hakka culture. The patio-style buildings and high-lighting buildings that represent the local characteristics of Jiangxi are found exactly in central Jiangxi. The relatively diverse set of architectural features and artistic elements is due to a variety of intertwined regional cultures. Compared with those of the surrounding provinces, the economic level of Jiangxi is relatively underdeveloped, and the local architecture has accordingly formed a restrained, simple, and practical artistic style.
