Introduction to Dai Village: The Dai people are mainly distributed in southern Yunnan, my country, located at the starting point of the Tea Horse Road. The residential buildings of the Dai people are mainly Ganlan (commonly known as bamboo buildings). The upper and lower floors are made of wood and bamboo as piles, floors and walls. The roof is covered with thatch and tiles. People live on the upper floor, while livestock are raised and farm tools and other items are piled on the lower floor. The entire building has tall spaces, and the walls and floors are made of bamboo or wood, which helps keep the room dry and cool.
