Introduction to the barn of the Yao people: The tall barn of Baiku Yao in Nandan County is extremely simple, but very practical. First, the barn is supported on a tic-tac-toe frame composed of four wooden columns, which can prevent moisture; second, A clay pot with a big belly and a small mouth is placed upside down on the top of each of the four wooden pillars to prevent rats; thirdly, keeping it away from the house can not only increase the living area, but also avoid unfortunate fire losses. The Yao people have simple folk customs. Although the barn is far away from the house, no one steals the rice.
