《后汉书·列传·虞傅盖臧列传》
史官评论说：曹操包围张超于雍丘，臧洪感慨愤激到了极点，想见他赤脚号泣、整顿戎装、请兵救援的情状，真是可怜啊！
论曰：雍丘之围，臧洪之感愤壮矣！想其行跣且号，束甲请举，诚足怜也。
The historian commented: When Cao Cao besieged Zhang Chao in Yongqiu, Zang Hong was extremely moved and lamented, thinking of him crying barefoot, tidying up his military uniform, and asking for troops to come to the rescue, which was really pathetic!
