Xidi and Hongcun are well known for their houses built in the Ming and Qing Dynasty. The houses in Xidi and Hongcun look very much the same, as if they are created by the same group of community. They are painted in black and white, black roofs covering the top of the white houses. Established for over 10 centuries, colour fades into gray instead of black and white, but we can still spot the contrast in distance. With the dwellings gathered in front of the mountains, and ducks swimming in ponds, a classical Chinese painting is presented vividly in the eyes of visitors. Appearing to be a disappeared non urban settlement which do not exist in anywhere else, Xidi and Hongcun villages were included as UNESCO world culture heritage in 2000.
