As tourism becomes a popular industry for domestic investment in recent years，it is greatly concerned by government at different levels and investors. However，in the current condition of increasingly expanding tourism investment size，problems of homogeneous competition and low-efficiency investment emerge. As homestay is a currently heated sub-category of tourism investment，the Mogan Mountain Homestay becomes a good case for reference：its investment problems，and the government’s active and exploratory scheme in tackling the problems，provide a prototype for tourism investment. The case proves that only maintaining sensibility in the investment trend，establishing investment rules，defining investment boundary and deploying the Blue Ocean Strategy，could prevent investment bubble，and encourage a healthy growth of domestic tourism investment.
