《资治通鉴·汉纪·汉纪三十五》
于是车师前王国、鄯善国、焉耆国等十八国，同时派他们的王子到洛阳充当人质，奉献珍宝。等到晋见皇帝刘秀时全都痛哭流涕地叩头，希望汉朝再派西域都护。
车师前王、鄯善、焉耆等十八国俱遣子入侍，献其珍宝；及得见，皆流涕稽首，愿得都护。
So eighteen countries, including the kingdoms of Cheshi, Shanshan, and Yānqí, sent their princes to Luoyang to serve as hostages at the same time, offering treasures. When they met with Emperor Liu Xiu, they all wept and kowtowed, hoping that the Han would send a Protector General to the Western Regions again.
