《宋书·列传·卷九十五》
如果不是仰仗宋朝的威望，顺从人民的意愿，怎么会取得这么大的成果。 今天平城的残暴政权，与柔然激战不停，东西不能兼顾，敌人兵势不能相结，长安成了一座孤城，河洛一带的城池无人看守。
义风一鼓，率士响同，威声既张，士卒效勇，师不崇朝，群狡震裂，殄逆鳞于函关，扫凶迹于秦土，非仰协宋灵，俯允群愿，焉能若斯者哉！
If I hadn't relied on the prestige of the Song Dynasty and obeyed the wishes of the people, how could I have achieved such great results? Today, the brutal regime in Pingcheng is constantly fighting against Rouran. It cannot take care of both the east and the west, and the enemy's forces cannot be united. Chang'an has become an isolated city, and the cities in Heluo area are unguarded.
