《北齐书·列传·卷十六》
这时韶突然在军中病倒，由于内城还没有攻下，他对兰陵王长恭说： 此城三面是深涧，没有退路，只有东南一处可以与外面沟通。
时韶病在军中，以子城未克，谓兰陵王长恭曰： 此城三面重涧险阻，并无走路，唯恐东南一处耳。
At that time, Shao suddenly fell ill in the camp and, as the inner city had not yet been taken, he said to the Prince of Lanling Changgong: The city has chasms on three sides and no way to escape; only the southeast side can be used to communicate with the outside.
