Bai ethnic minority is typically a minor group in Yunnan China. Their buildings are very special. The traditional Bai ethnic minority folk houses give the city distinctive feel. A typical house is characterized by “3 rooms and a wall screening” and “4 joints and 5 yards”. The first style means that every house has a principle room and 2 wing-rooms and facing the principle room stands the wall screening. When the sun shines on the wall screening in the afternoon, the sunlight is reflected back to the courtyard, thus illuminating the whole area. The 2nd style means houses are built with 4 sides; and 4 courtyards in the joining parts of the houses’ corners and one big courtyard in the center makes 5 courtyards. The decoration pays great attention to the gate tower, the eaves and corners. The windows, the walls and the doors are decorated with Jianchuan Woodcarvings, colored patterns, marbles and wash drawings. The houses there are all with grey-green roof tiles, peculiar workshops, temples, schools, etc. the delicacy, freshness and elegance of their construction may be called first-class among folk residences in Southwest China. When people walk along the cobble-paved streets in the ancient city, a sense of primitive simplicity and elegance will be invoked.
