Tongdao Dong people use epic pure wood construction techniques to embody their beautiful pursuit and core values of worshipping nature, adapting to nature, and living in harmony with nature, and they carry a profound and magical Dong culture system. They use the skills of "picking up beams and erecting melons, mortise and tenon joints, close buckling without gaps, and carved beams and painted buildings" to organically integrate folk architecture, painting, and sculpture art, reaching a high level of architectural art. Complex and gorgeous wooden structures are scattered all over Tongdao Dong Village and are completely organically combined. Their construction techniques are exquisite and their ethnic characteristics are obvious, which is amazing. Stilt houses originated from the nests of the ancient Baiyue ethnic group, drum towers originated from the legacy of "singing and dancing under the tree", wind and rain bridges originated from the legend of Qinglong Gengu, and village gates originated from defense functions and regional definitions, etc., are everywhere in Tongdao Dong Autonomous County. These national treasures are concentrated in the ethnic building complex in Tongdao. They are the product of the development from stilt buildings to ground buildings with the development of construction technology. They reflect the wooden building construction skills and extraordinary aesthetic pursuit of the Dong ethnic group in a specific period and specific area in the "Chu Yue Ancient Passage". They have important research value and are important achievements of the southern Dong people in architectural construction, landscape design, engineering construction or plastic arts.
