范延光
Li Siyuan died in late 933 and was succeeded by his biological son Li Conghou the Prince of Song. In early 934, his chiefs of staff Zhu Hongzhao and Feng Yun, not wanting Shi Jingtang, who was then the military governor of Hedong, to become entrenched there, issued orders transferring Li Conghou's older adoptive brother Li Congke the Prince of Lu from Fengxiang Circuit (鳳翔, headquartered in modern Baoji, Shaanxi) to Hedong, Shi from Hedong to Chengde Circuit (成德, headquartered in modern Shijiazhuang, Hebei), and Fan Yanguang from Chengde to Tianxiong Circuit (天雄, headquartered in modern Handan, Hebei).
