《汉书·传·张骞李广利传》
汉武帝认为张骞说得对，授予张骞中郎将的官职，率领三百人，每人马各二匹，赶着上万计的牛羊，随身携带价值数千万万的黄金和礼物，还有许多持节副使随行，出使乌孙。
天子以为然，拜骞为中郎将，将三百人，马各二匹，牛、羊以万数，赍金币帛直数千巨万，多持节副使，道可便遣之旁国。
Emperor Wu of The Han Dynasty thought Zhang Qian was right, so he awarded Zhang Qian the position of Zhonglang General, led three hundred men, each with two horses and tens of thousands of cattle and sheep, and carried gold and gifts worth tens of millions, as well as many envoys and deputy envoys. He sent them to Wusun.
