《太平广记·卷八十二·异人二》
第二天嘉祚又上了朝，果然被两个宰相所召见，二相迎士前来对他说： 我们知道您的行为功绩向来很高，所以让您带上朝廷的使命去充当使节。
明复至朝，果为二相所召，迎谓曰： 知公迹素高，要公衔朝命充使。
The next day, Jia Zuo went to court again, and was indeed summoned by the two prime ministers. The two came forward to greet him and said: "We know that your behavior and merits have always been very high, so we ask you to take on the mission of the court and serve as an envoy."
