In 77 BCE, the Chinese envoy Fu Jiezi was sent to kill the Loulan king, named Changgui or Angui (嘗歸 or 安歸), after several Han envoys were kidnapped and killed. He arrived on the pretext of carrying gold and valuables to the outer states and intending to give a presentation to the king, but stabbed the Loulan king to death while he was drunk. The king's younger brother Weituqi (尉屠耆) was then installed as the king of Loulan by the Han ruler, and the kingdom was renamed Shanshan.
