《新唐書•方鎮表》載昭義軍所轄澤州自844年後，即劃歸河陽節度使，不再還隸。本文將考證在857-859年間，澤州再次還隸昭義軍節度使管轄，《新唐書•方鎮表》乃誤，後人若襲之亦將誤用。

Xin tang shu Fang zhen biao (新唐書•方鎮表) says Zezhou (澤州) was handed over to the Heyang Jiedushi (河陽節度使) in 844AD from the Zhaoyijun Jiedushi (昭義軍節度使), and it would not be under the jurisdiction of the Zhaoyi Jiedushi again. However, the author found that Zezhou was actually returned to the Zhaoyijun Jiedushi (昭義節度使) between 857-859AD and proved the error of what the Xin tang shu Fang zhen biao had indicated.
