Abstract: It is a prominent phenomenon that the region of private life was overspreaded in public administration system before transition. At that time person's private life was almost hidden in the state governance system. Exploring the historical origin of the phenomenon,the paper thinks the background characteristic of times lies in elimination and disenchantment of supernatural charm of the China traditional patriarchal society;and the logical source lies in the coupling between the western enlightenment discourse and the Chinese survival since the opium war. On the basis,the revolutionary discourse had been dominant on the development and operation of Chinese society until the Third Plenary Session of the 11th Committee of CPC. And so much,the people's private space was enveloped in the public administration.
