Guo Ziyi
When Guo arrived at the Uyghur's camp, he did not reveal his identity and appeared to be a messenger who had been sent to tell them that Guo Ziyi was coming to see them. The Uyghur chieftains, many of whom had joined the rebel side in the An Lushan Rebellion, were surprised and panicked to hear that Guo was alive, deciding that they had to meet with him. Guo laughed at them and asked them why they would want to face Guo Ziyi again after their defeat at his hands during the An Shi Rebellion. The Uyghur chieftains replied they had been told that he was dead, but if they met with him and saw he was alive, they would retreat. Guo, however, insisted that Guo Ziyi did not seek their retreat but instead wanted them to join him against the Tibetans. The Uyghur chieftains, saying they had been deceived by the Tibetans about Guo's death, agreed to break the alliance with them. They even claimed that shamans had foretold that a great man would lead them to victory and that they now believed this man must be Guo, and agreed to join forces with the Tang.
