《资治通鉴·唐纪·唐纪四十三》
陛下何必顾惜杨炎暂时的声誉，而毁坏了大功业，不如暂时免除杨炎的相职，使李希烈高兴，事情平息以后再起用杨炎，这并没有什么妨害。 
陛下何爱炎一日之名而堕大功？不若暂免炎相以悦之。事平复用，无伤也。 
Why should Your Majesty care about Yang Yan's temporary reputation and ruin your great career? It is better to temporarily dismiss Yang Yan from his position as prime minister, so that Li Xilie will be happy and the matter will be settled. After the incident, it will not be a hindrance to use Yang Yan again.
