《资治通鉴·梁纪·梁纪六》
西丰侯萧正德从北魏返回之后，思想和行为方面没有一点悔改之意，大量召纳亡命之徒，夜间在道路上杀人越货，他被任命为轻车将军跟随萧综北伐，丢下军队私自返回。
西丰侯正德自魏还，志行无悛，多聚亡命，夜剽掠杀人于道，以轻车将军从综北伐，弃军辄还。
After returning from Northern Wei, Duke Xifeng, Xiao Zhengde, showed no repentance for his actions or thoughts; he gathered many fugitives, robbed and killed people on the road at night; he was appointed General of Cavalry and accompanied Xiao Zong on the Northern Expedition, but he abandoned his troops and returned alone.
