《后汉书·列传·独行列传》
到职的第二年，派人迎接他的母亲和妻、子，快到郡了，经过柳城，碰上鲜卑一万多人入塞侵犯掳掠，赵苞的母亲及妻、子，被鲜卑劫持作人质，用车子载了攻击郡境。
以到官明年，遣使迎母及妻子，垂当到郡，道经柳城，值鲜卑万余人入塞寇钞，苞母及妻子遂为所劫质，载以击郡。
Two years after he assumed his new position, he sent someone to welcome his mother, wife and son. When they were almost at the prefecture and passing Liu Cheng, they encountered more than 10,000 Xianbei who had invaded and raided the border. Zhao Bao's wife, son and mother were taken hostage by the Xianbei, who then loaded them onto a cart as they attacked the prefecture.
