《资治通鉴·唐纪·唐纪十四》
我刚才经过各处营房，看见士兵们听说高丽兵到了，都拔刀扎旗，喜形于色，此乃必胜的士兵。
臣适行经诸营，见士卒闻高丽至，皆拔刀结旆，喜形于色，此必胜之兵也。
I just passed by the barracks and saw that when the soldiers heard that the Goryeo army had arrived, they all took out their swords and planted flags, and their faces were full of joy; these are bound to be victorious soldiers.
