《资治通鉴·梁纪·梁纪四》
萧秀虽然和梁武帝在贫贱时是兄弟，等到成为君臣关系之后，对梁武帝的谨慎小心、恭恭敬敬超过了朝中那些关系疏远、出身低贱的臣子，梁武帝也更因此而认为他贤良。
秀虽与上布衣昆弟，及为君臣，小心畏敬过于疏贱，上益以此贤之。
Although Xiao Xiu and Liang Wu Di were brothers in their poverty-stricken days, after becoming monarch and minister, he was more cautious and respectful towards Liang Wu Di than distant and lowly-born ministers in the court, which made Liang Wu Di thought he was virtuous.
