《宋书·列传·卷七十四》
后来臧质又留恋宠姬爱妾，丢下军队，一个人回到襄阳，把雍州府仓库的现钱用了六七百万，被有关部门弹劾，文帝没有追究这些。
质又顾恋嬖妾，弃营单马还城，散用台库见钱六七百万，为有司所纠，上不问也。
Later, Zang Zhi missed his favorite concubine and left the army to return to Xiangyang alone. He used 6 to 7 million yuan in cash from the Yongzhou government warehouse, and was impeached by the relevant departments.
