《资治通鉴·唐纪·唐纪五十四》
裴说： 吐突承璀首先提倡使用武力，使天下百姓穷乏困苦，到头来还是不能获得成功。即使陛下因旧日的恩情而不肯将他处决示众，为了向天下百姓道歉，难道能够对他全然不加贬斥吗？ 
裴垍曰： 承璀首唱用兵，疲弊天下，卒无成功，陛下纵以旧恩不加显戮，岂得全不贬黜以谢天下乎！ 
Pei said: "Tu Tu Cheng Cui was initially an advocate for force, leading the country into poverty and hardship, that does not justify his crimes. Even if Your Majesty were to spare his life, would you also not depose him, as an apology to the people?"
