《旧五代史·后晋·列传十二》
杨光远捎信上奏 ：我贵为将相，没有不满足的，只因张生铁死得其所，我不如他，心中内疚，因此不高兴。 
光远附奏曰： 臣贵为将相，非有不足，但以张生铁死得其所，臣弗如也，衷心内愧，是以不乐。 
Yang Guangyuan wrote a reply: “I am greatly honoured to be a general and a minister, and have no dissatisfaction. However, Zhang Shengtie died for his country, and I am unworthy of him. Therefore, I feel guilty and unhappy.”
