《新唐书·列传·卷一百四十三》
绛州刺史劝景思多召些兵，景思乃回代州，募兵三万，屯扎崞西，士兵们犷悍横暴，李友金驾驭不了，乃与陈景思商议 ：如今招募了这些兵，如没有威信高的宿将来统率，终将无功。
还代州，益募士三万，屯崞西，士嚣纵，友金不能制，谋曰： 今合大众，不得威名宿将，且无功。
Jiangzhou Prefect advised Jingshi to recruit more soldiers; Jingshi returned to Daizhou, recruited thirty thousand soldiers, and set up camp at Hexi. The soldiers were unruly and violent, and Li Youjin could not control them; he discussed the matter with Chen Jingshi: "Now that we have recruited these soldiers, if we do not have a highly respected veteran to lead them, they will end up being useless."
