Бань Чао
For more than thirty years Ban Chao worked in the Western Regions until he was seventy, when he retired and returned to Luoyang. Ren Shang succeeded Ban Chao as the Protector General of the Western Regions in 102, but as he was unkind and harsh toward the local people, they rose against him, plunging the region into disorder. The Han court soon recalled him in 106, and replaced him with Duan Xi. On July 29, 107, the Han government abrogated the protector generalship, and recalled Duan Xi back under the escort of General Wang Hong.
