《旧唐书·列传·卷八十三》
大营击鼓呐喊，李演奋力拼杀，大败叛军，乘胜攻进光泰门；叛军再来接战，又被打败，叛军死尸遍地，残兵逃进白华，夜里还听见痛哭声。
中军鼓噪，演力战，大破之，乘胜入光泰门；再战，又败之，僵尸蔽地，余众走入白华，夜闻恸哭之声。
The large camp beat the war drums and shouted. Li Yan fought hard, defeated the rebels badly and took advantage of the victory to charge into Guangtai Gate. The rebels fought back again, but were defeated. The rebels' corpses were everywhere and the remnants fled into Baihua. Their cries could still be heard at night.
