The female self is primarily an emotional subject with the dual features of inclusion and exclusion. The significance of the female self for society lies in the fact that the inclusive aspect provides a psychological and practical basis for the integration of rural society, while the exclusive aspect creates a space for breaking through this society＇s existing norms and customs.展开更多

文摘On the basis of the findings of our fieldwork in Shuanglong Village of the Tujia ethnic group in Enshi, Hubei, we find that woman is neither the subjectless existence of＂otherness＂ as traditionally regarded nor the rational subject embodying multiple survival strategies as defined by some scholars. The female self is primarily an emotional subject with the dual features of inclusion and exclusion. The significance of the female self for society lies in the fact that the inclusive aspect provides a psychological and practical basis for the integration of rural society, while the exclusive aspect creates a space for breaking through this society＇s existing norms and customs.
