《资治通鉴·梁纪·梁纪二十二》
第二天，各位王公聚集在一起议论国家大事，于谨说： 过去孝武帝受到高欢协迫，魏国帝室陷于倾覆的危险之中，要不是安定公迎纳并辅佐了他，国家就没有今天这种局面了。
明日，群公会议，谨曰： 昔帝室倾危，非安定公无复今日。
The next day, when the princes gathered together to discuss the national affairs, Yu Jin said: In the past, Emperor Xiaowu was coerced by Gao Huan, and the Wei imperial house was in danger of being overthrown. If it were not for the Duke of An Ding who welcomed and assisted him, the country would not be in the situation it is today.
