Abstract: The Inspecting Censor was a specific supervisory official in Yongzheng Reign．When Inspecting Censors patrolled provinces，they got involved in local politics through non-institutionalized power and participated in the implementation of new policy as well as the extensive reforms that Emperor Yongzheng promulgated．On the one hand，the lack of regulation of the system made the administration of the Inspecting Censor flexible which was of great benefit to improving the age － old malpractice of local government．On the other hand，deficiencies in the system led to the contradictions among duty，power and position，so that the Inspecting Censor became a redundant element of administration and it was eventually abolished．This article will examine the institutional origin and establishment of the Inspecting Censors，their involvement in local politics and the actual extension of their power，and will explore the deep-rooted institutional reasons for its abandonment．On the one hand，the rise and the abolishment of the Inspecting Censor was related to the political trends of the Yongzheng Reign．On the other hand，the fate of the Inspecting Censor sheds light on the design and the practice of the administrative system of the Qing dynasty．
