《宋史·列传·卷七十一》
王韶夺取洮州，部族酋长木征逃离，吴充请求收回旧地，用官爵来加以安抚，让他们各自统领自己的部落，永远为外臣，不要建置郡县，耗尽财物和力量。
王韶取洮州，蕃酋木征遁去，充请招还故地，縻以爵秩，使自领所部，永为外臣，无庸列置郡县，殚财屈力。
Wang Shao captured Taozhou, and the tribal leader Mu Zheng fled. Wu Chong requested to recover the old land, appease them with official titles, let them each lead their own tribes, be foreign ministers forever, and not build counties and towns, which would exhaust their wealth and strength.
