《北史·列传·卷三十四》
萧综诚心归降，听说鹿悆被抓住，对成景俊说： 我常怀疑元略劝我献城投降，想验证一下他是否是真心实意，便派左右心腹作为使者，到魏军中，让他们派一个人来。
综既有诚心，闻悆被执，语景俊等曰： 我每疑元略规欲叛城，将验虚实，且遣左右为元略使，入魏军中唤彼一人。
Xiaozong sincerely surrendered. Hearing that Lu Ji had been captured, he said to Cheng Jingjun, "I often doubted that Yuanlue had persuaded me to offer the city and surrender. I wanted to verify whether he was genuine, so I sent my left and right confidants as envoys to the Wei army, asking them to send someone."
