《史记·七十列传·魏公子列传》
赵孝成王感激公子假托君命夺取晋鄙军权从而保住了赵国这一义举，就与平原君商量，把五座城邑封赏给公子。
赵孝成王德公子之矫夺晋鄙兵而存赵，乃与平原君计，以五城封公子。
King Xiaocheng of Zhao was very grateful that Gongzi borrowed the king's command to take over command of Jin Bi's army, thus preserving the state of Zhao. He discussed with Lord Pingyuan about rewarding Gongzi with five cities.
