Fan Yanguang
In 931, Zhao Yanshou was promoted to serve as Li Siyuan's chief of staff ("Shumishi"), serving with Fan Yanguang. However, as Zhao was replacing the long-time chief of staff An Chonghui, whose domination of the court scene eventually led to his downfall and death, both he and Fan feared the same fate and therefore avoided ruling on important matters. That allowed LI Siyuan's favorite concubine Consort Wang and the eunuch Meng Hanqiong to take control over much of the important affairs of state. While serving as chief of staff, Zhao also carried the military governorship of Wuning Circuit (武寧, headquartered in modern Xuzhou, Jiangsu).
