Flying-mountain God Yang Zaisi is an important local God worshipped by the Dong-Miao group in the juncture area of Hunan,Guizhou and Guangxi. But it lacks official records,and the four major groups,officials and local elites,the local people,clan members and writers,have jointly created its legendary narration by inscriptions,genealogies,oral legends and literary works. The multiple narration based on the historical memory and local society of the Dong-Miao group helps create Yang Zaisi as a perfect and heroic god with local and ethnic features,whose interpretation can help reveal the diversity,complexity and locality of Dong-Miao’s social and historical evolution in different aspects.
