Buildings are fixed, but by people's hands present that they are not of uniform size, well-proportioned, intelligent and freely, the one and only appearance, as well as exquisite, new and unusual decorations and so on. They are splendid like music. A famous German writer, poet Goethe said: 'Music is flowing buildings, and buildings are concretionary music.' Folk Houses are important forms of buildings. They are ubiquitous architectural forms among the people, and have many elegant and unconventional buildings.
