《资治通鉴·唐纪·唐纪十一》
从前秦穆公给盗马的野人喝酒，楚庄王赦免因调戏宫姬被扯断帽缨的臣下，最后都得到加倍的回报，难道陛下道高于尧、舜，而却赶不上秦穆公、楚庄王二人吗？ 
昔秦穆饮盗马之士，楚庄赦绝缨之罪，况陛下道高尧、舜，而曾二君之不逮乎！ 
In the past, Duke Mu of Qin gave wine to a savage who stole a horse, and King Zhuang of Chu pardoned his subjects who had their hat tassels torn off because they molested the palace concubine, and finally got double the reward. Is your Majesty's morality higher than that of Yao and Shun, but not as good as Qin Mugong, King Zhuang of Chu?
