《北史·本记·卷二》
皇帝生下来后就没有见到密太后，当他开始懂事以后，一提起来就十分悲伤，这种哀伤的感情使旁人都为之动心，明元帝知道以后很赞赏并感叹不已。
帝生不逮密太后，及有所识，言则悲恸，哀感傍人，明元闻而嘉叹。
The Emperor had not seen Empress Mi since he was born, and when he began to understand, he was very sad when he mentioned it. This sad emotion moved everyone around him. Emperor Mingyuan was very appreciative and sighed with emotion after learning about it.
