《后汉书·列传·班梁列传》
月氏从此受到极大震动，每年都向汉朝进贡。永元三年，龟兹、姑墨、温宿都投降了，朝廷任命班超为郡护，徐干为长史，立白霸为龟兹王，派遣司马姚光护送他。
明年，龟兹、姑墨、温宿皆降，乃以超为都护，徐为长史。拜白霸为龟兹王，遣司马姚光送之。
Yuezhis was greatly shaken from there on, and paid tribute to the Han dynasty every year. In the third year of Yongyuan, Qiuci, Gumo, and Wensu all surrendered, and the imperial court appointed Ban Chao as the protector of the county, Xu Gan as his assistant, and established Bai Ba as the king of Qiuci, and dispatched Sima Yao Guang to escort him.
