《资治通鉴·唐纪·唐纪四十三》
四人各自将所管理的州改为府，设置留守兼元帅，将军政委托给他们。又设置东西两曹，来比附中书省和门下省；设置左右内史，来比附侍中和中书令。其余官职一律模仿朝廷的建制，只是改换了名称。
各以其所治州为府，置留守兼元帅，以军政委之；又置东西曹，视门下、中书省；左右内史，视侍中、中书令；馀官皆仿天朝而易其名。
The four men each changed the states they governed into prefectures, established governors who also served as marshals, and delegated military and political power to them. They also established east and west "cao", which were similar to the Zhongshu Province and Menxia Province; they established left and right "nei shi", which were similar to the "shi zhong" and "zhong shu ling". The rest of the official positions were modeled on the imperial court, with only the names changed.
