《资治通鉴·汉纪·汉纪十六》
从此，皇曾孙以许广汉兄弟和祖母娘家史家为依靠，又跟随东海人中翁学习《诗经》。皇曾孙聪明好学，但也喜爱游侠之事，斗鸡走狗，所以对下层社会的奸邪丑恶和官吏的好坏得失了解得十分清楚。
曾孙因依倚广汉兄弟及祖母家史氏，受《诗》于东海澓中翁，高材好学；然亦喜游侠，斗鸡走狗，以是俱知闾里奸邪，吏治得失。
From then on, the great-grandchild of the emperor relied on Xu Guang Han's brother and his grandmother's family, the Shi family. He also studied the Book of Poetry with Zhong Weng, an Eastern Sea native. The great-grandchild of the emperor was clever and eager to learn, but he also enjoyed chivalrous adventures, such as fighting cocks and dogs. Therefore, he understood very well the evil and ugliness of lower-class society and the gains and losses of officials.
