The architectural art of the Li ethnic group is reflected in their cottages. The cottages in Baicha Village are well preserved boat-shaped houses. The Li people constructed boat-shaped cottages for thousands of years. The material is simple and of high quality, demonstrating the technical mastery of the Li ethic group. Boat-shaped cottages look like upside-down vessels, and the thatch-eaves are low. This design is stable and protects from rain and wind.
