《资治通鉴·汉纪·汉纪二十九》
匈奴单于栾提知，当初曾因夏侯藩要求割地而说过拒绝汉朝的话，后来因为向乌桓索取贡品而没有得到，攻击劫掠乌桓百姓，中国和匈奴从此产生裂痕。加以印文改换，所以对中国怨恨。
单于始用夏侯籓求地，有拒汉语，后以求税乌桓不得，因寇略其人民，衅由是生，重以印文改易，故怨恨。
When the Xiongnu chanyu Ruoti heard that, earlier on he had said that he would refuse the Han Dynasty because Xiahou Fan had requested that he cede territory, later because he failed to get tribute from the Wuhuan, he had attacked and plundered the Wuhuan people, this created a rift between China and the Xiongnu. In addition, the seal had been changed, and so he was resentful towards China.
