杨国忠
The novel is set in the Tianbao era (742–756) of the Tang dynasty during the reign of Emperor Xuanzong. The emperor appoints the incompetent Yang Guozhong as chancellor because his cousin, Yang Yuhuan, is the emperor's favourite concubine. Nepotism and cronyism prevail as Yang Guozhong places his relatives and supporters in high-ranking posts in the Tang government, which becomes increasingly corrupt over time. The power-hungry barbarian An Lushan wins the emperor's trust through flattery and gets promoted to the position of "jiedushi" (military governor) of Fanyang. An Lushan wields great power in his hands and secretly builds up his military forces in preparation for a rebellion.
