宗楚客
Meanwhile, Wuzhile's subordinate Juechuo Zhongjie () was unwilling to submit to Suoge. Juechuo was, however, unable to prevail over Suoge, and in 708, at Guo's suggestion, he was set to give up his forces and go to the Tang capital Chang'an, when the Tang general Zhou Yiti () suggested to him the idea of bribing the chancellors Zong Chuke and Ji Chuna to launch an attack against Suoge. Juechuo did so, and Zong, after Juechuo's bribery, proposed to Emperor Zhongzong the idea of attacking Suoge in alliance with the Tibetan Empire, which Emperor Zhongzong agreed despite Guo's opposition. Suoge heard of this plan and acted first, successfully attacking several Tang outposts and then sending an envoy to Chang'an to demand that Zong be executed. Subsequently, Guo reported the facts of the situation to Emperor Zhongzong, which led to Zong's accusing him of treason. However, Emperor Zhongzong agreed with Guo and sent a peace envoy to make peace with Suoge and creating him Shisixing Khan.
