In the perspective of new historicism,the true history consists of two parts:the"Historical facts"created by heroes under the great historical view,and the"historical stories"narrated by common people under the little historical view.As one of the two ways talking about history,folk oral narrative exists with its oral history character of"marginalization"and "micro-politics",forms joint force and separating force with the official history.On the one hand,oral history continuously strengthens the events or emotions in official history by folk oral narrative and doing addition for official history records.On the other hand,oral history continuously deletes or filters out the historical events and group feelings that are not accepted by the subaltern,doing subtraction for official history records.It is the mutual complementation of joint force and separating force,addition and subtraction that finishes the overall construction and emotional inheritance of regional cultural history.
