In AD 108, "the Kiang or Tibetans, who were then entirely savage and lived a nomadic life west and south of the Koko-nor, attacked the Chinese posts of Gansu, threatening to cut the Dunhuang road. Liang Kin, at the price of some fierce fighting, held them off." Similar incursions were repelled in AD 168-169 by the Chinese general Duan Gong.[6]
