《宋书·志·卷十五》
使持节侍中、给事黄门侍郎应该像旧时的典章所说的那样，详细条列奏报各地的情况，使我对遥远地方的情形能清楚明了，就像是亲自巡行到了边远地方一样。大夫君子们，各人应该竭尽自己的诚心，各自敬谨你们的职事，有好的谋略、好的规划，有至诚的进言和劝诫，应该对使者详尽地陈述，不要有隐讳。
还具条奏，俾朕昭然鉴于幽远，若亲行焉。大夫君子，其各悉乃心，各敬乃事，嘉谋令图，苦言至戒，与使者尽之，无所隐讳。
The imperial commissioners, the Gentleman Attendant and Vice Secretary of Department of Gentlemen-in-Waiting, should fully enumerate and report the conditions everywhere in the empire, as the ancient code says, in order for me to have a clear understanding of the conditions in distant places as if I had personally toured the remote areas myself. Gentlemen and learned scholars, each and every one of you should offer your heartfelt sincerity, each of you should be respectful in carrying out your duties, you should all have good strategies and good plans, you should give sincere advice and admonitions; you should all state everything in detail to the envoys, without any concealment.
