《资治通鉴·唐纪·唐纪二》
李世民说： 宗罗的部下都是陇山之西的人，将领骁勇，士卒剽悍；我只是出其不意打败了他，杀伤不多。
世民曰： 罗侯所将皆陇外之人，将骁卒悍；吾特出其不意而破之，斩获不多。
Li Shimin said: "Zong Luo's subordinates were all from west of Longshan, the generals were brave and the soldiers valiant; I only took him by surprise and defeated him, there was no great loss of life."
