《三国志·魏书·武帝纪》
从前在周朝时，毕公、毛公都曾入朝作公卿，周公、邵公不但在朝中作太师、太保，也在外作一方之伯。内外兼职，对于您是非常合适的，您仍以丞相的身份兼任冀州牧。
昔在周室，毕公、毛公入为卿佐，周、邵师保出为二伯，外内之任，君实宜之，其以丞相领冀州牧如故。
In the past during the Zhou Dynasty, Bi Gong and Mao Gong had both entered the DPRK as public officials, and Zhou Gong and Shao Gong were not only teachers and Taibao in the DPRK, but also Bo in a certain way. It is very suitable for you to hold both positions at home and abroad. You still serve as the governor of Jizhou as the prime minister.
