The research shows that since the Neolithic Age,the people living in Zhejiang province have created rich and colorful folk beliefs in the process of understanding the environment,enhancing self- awareness and seeking the means of survival and development. These beliefs not only play an important role in their production,life,and organization,but also are in constant changes,following the development of the society. The process of their transformation not only fully reflects the socio- economic and cultural situations in this region,but also mirrors the entire historical changes of Chinese society,including the population,the migration and the process of cultural collisions and fusion,as well as all the beliefs,policy orientations and administrative means of the previous rulers. Though the previous feudal dynasties tried to control or forbid the folk beliefs in Zhejiang,these beliefs remained alive due to the unpredictable natural disasters on the one hand and the tense social relations of the authoritarian society and the rulers’ value orientation on the other. The nature of such control aimed to replace the existing loose and ineffective form of social control with a new form of the mainstream value penetration,and to lay a broader and sounder social basis for the legitimacy and authority of the feudal kingdom.
