《资治通鉴·唐纪·唐纪六十二》
如果陛下担忧黄河在冬天结冰后，回鹘再次纵兵侵扰，打算早日出兵驱逐他们，那么，就应当在天气尚未寒冷以前，尽早作出决策，把河朔藩镇的兵力调拨给河东，争取在两个月内完成战斗。
若虑河冰既合，回鹘复有驰突，须早驱逐，则当及天时未寒，决策于数日之间。以河朔兵益河东兵，必令收功于两月之内。
If Your Majesty is worried that after the Yellow River freezes in winter, the Uighurs will invade again and plans to send troops to expel them as soon as possible, then the decision should be made before the weather becomes cold, and the troops of the Hebei Fan town should be transferred to Hedong, and strive to complete the battle within two months.
