Abstract: The Chong-Fan-Pi-Nan System administrative grading system was established in Qing Dynasty. Following the further excavation of historical archives, scholars need to reexamine many assertions about this system. First, there were f ive corresponding relationships between the four attributes and four grades. The customized corresponding relationship was just one of them, but not the most rational one that the autocratic government enforced. Second, owing to the complex relationship between grades and attributes, and the subdivision of the attributes into different grades, the imperial court forced a unity among the relationships that tended to standardize the relationship and simultaneously make the system simple and inflexible. Third, the adjustment of def icient grade was the result of a combination of objective and subjective reasons. Thesubjective reasons were more obscure and easily omitted, thus concealing the real motivation for the conduct and power claims.
