In this paper, we address interesting questions about how feng shui influences house price from a data perspective. First, is feng shui likely to influence house price? Second, how do different feng shui features, e.g., house shape, master bedroom location, and other interior room arrangements, influence the price? Third, can we automatically diagnose the feng shui problems of a house? From a dataset of 4,579 items of information on houses in Taipei City, we automatically infer what factors determine the house price and identify the feng shui problems of a house that may lower a home's economic value.
