《资治通鉴·唐纪·唐纪七十》
豆卢说： 先前哥舒翰率领十五万大军尚不能把守潼关，今天黄巢贼众有六十万，而潼关又没有象哥舒翰当年那样强大的军队。
豆卢彖曰： 哥舒翰以十五万众不能守潼关，今黄巢众六十万，而潼关又无哥舒之兵。
Dou Lu said: Previously, Geshu Han led an army of 150,000 men but could not defend Tong Pass; today, Huang Chao has 600,000 rebels, and Tong Pass does not have as strong an army as Geshu Han did.
