《三国志·魏书·武帝纪》
徐荣见太祖带的兵虽少，但都能齐心奋战，坚持了一天，认为酸枣不易攻克，也领兵返回。
荣见太祖所将兵少，力战尽日，谓酸枣未易攻也，亦引兵还。
Seeing that although the First Ancestor led only a small number of soldiers, they all fought unitedly and persisted for one day, Xu Rong believed that Suanzao would not be easy to conquer, and he also led his troops back.
