Chinese people used to invite experts to advise them in feng shui principles before building a house. It seems to be superstitious, but somehow makes sense. According to the Chinese people, no building should mar the harmony of nature, but instead blend into nature. Those living in such houses would not feel confined in cages, but as if they were living in serene nature. Thus, Chinese houses usually face the south so as to have warm sunshine in winter and cool breezes in summer. The house, warm in winter and cool in summer, is comfortable for accommodation.
