《旧唐书·列传·卷八十四》
马燧就命大将李自良、李奉国率骑兵会同神策军在双冈抵御，下令道： 让田悦过来了，就杀了你们！ 
燧乃令大将李自良、李奉国将骑兵合神策军于双冈御之，令曰： 令悦得过，当斩尔！ 
Ma Sui ordered great general Li Ziliang, Li Fengguo and others to lead their cavalry together with the Shence Army to resist at Shuanggang, and gave the order: If you let Tian Yue pass, I will kill you all!
