李林甫
In 752, Geshu began to become part of the central government's intrigue, in the power struggle between the chancellor Li Linfu and Yang Guozhong, the second cousin of Emperor Xuanzong's favorite concubine Consort Yang Yuhuan, as both he and the chancellor Chen Xilie corroborated accusations that Li Linfu had friendly relations with Li Xianzhong (), an ethnically Tujue general who had been forced into rebellion earlier that year. This facilitated Yang Guozhong's aggrandizement of power and the reduction of Li Linfu's influence.
