Most Yi villages are large villages where Yi people live in compact communities. Before liberation, houses were mostly thatched houses or rough houses with civil structures. With doors and no windows, I am used to "dark room and bright stove". It is forbidden to open the door facing north, regardless of the door, stove door or stable door. After the founding of People's Republic of China (PRC), tile houses with buildings and residences were gradually built, and some of them also built brick and wood structures.
