《旧唐书·列传·卷五》
刘黑闼受唐军威逼，得不到休息，路途遥远士卒疲劳，到饶阳时，跟着他的才一百多人，大家都饥肠辘辘，想进城弄东西吃。
黑闼为王师所蹙，不得休息，道远兵疲，比至饶阳，从者才百余人，众皆馁，入城求食。
Liu Heita was pressed by the Tang army and could not rest. The journey was long and his soldiers were exhausted. When he arrived at Rao An only about a hundred men were still following him, and they were all hungry and wanted to enter the city to get something to eat.
