《论衡·卷十九·恢国篇》
当今哀牢、鄯善、婼羌投降内附服从汉朝统治，匈奴经常侵扰，派遣将领防御讨伐，活捉俘虏以千万计。
方今哀牢、鄯善、诺降附归德，匈奴时扰，遣将攘讨，获虏生口千万数。
Today, Ailao, Shanshan, and Ruoqiang surrendered and obeyed the rule of the Han Dynasty, but the Huns often invaded, and we dispatched generals to defend against and punish them, and captured prisoners numbering in the millions.
