《明史·列传·卷一百六十七》
永明王用君臣之义批评他，彭年恼火地说 ：假如过去惠国公带领他的五千铁骑鼓行而西，不管你，现在哪还有什么君臣之义？ 永明王变了脸色，非常厌恶他。
王责以君臣之义，彭年勃然曰： 傥向者惠国以五千铁骑，鼓行而西，君臣义安在？ 王变色，大恶之。
The Yongming King criticized him with the righteousness of the monarch and the minister. Pengnian said angrily, "If the Duke Huiguo had led his five thousand iron cavalry and marched west without caring about you in the past, would you still have the righteousness of the monarch and the minister?" The Yongming King changed his face and was very disgusted with him.
