Western Regions
In 107 CE, the Western Regions in modern Xinjiang province rebelled against Chinese rule. Ban Yong was appointed as a Major (Jun Sima 軍司馬) and, with his elder brother, Ban Xiong (班雄), went to Dunhuang to meet up with the Protector General of the Western Regions, Ren Shang, who had replaced Ban Chao as Protector General in 102 CE. The Chinese had to retreat and, following this, there were no Chinese functionaries in the Western Regions for more than ten years until Ban Yong returned in 126 CE.
