《新唐书·列传·卷七十九》
当时刘德信从扈间战败逃回，也驻军渭南，部队喧闹没有纪律，德信进营参见李晟，李晟责问他战败的原因，杀了他，带几个骑兵到德信的营垒慰劳他的军队，没有人敢妄动。
时刘德信自扈涧败归，亦次渭南，军嚣无制。德信入谒晟，晟责所以败，斩之，以数骑入壁劳其军，无敢动。
At that time, Liu Dexin fled back from the defeat in Hujian and also stationed troops in Weinan. His troops were noisy and undisciplined. Dexin entered the camp to meet Li Sheng. Li Sheng questioned him about the reason for his defeat, killed him, and took a few cavalrymen to Dexin's camp to comfort his army. Dare to act rashly.
