Fan Yanguang
In 934, by which point Li Siyuan had died and been succeeded by his son Li Conghou, Liu was made the prefect of Xin Prefecture (忻州, in modern Xinzhou, Shanxi) as well as the director of the military storage on the northwest front, to help defend against the Khitan Empire. However, after Li Conghou was shortly after overthrown by his adoptive brother Li Congke, Liu was recalled to the capital in 935 to continue to serve as a general of the imperial guards. In 936, when Li Congke was facing two rebellions — one by his brother-in-law (Li Siyuan's son-in-law) Shi Jingtang the military governor of Hedong Circuit (河東, headquartered in modern Taiyuan, Shanxi) and the Tianxiong Circuit (天雄, headquartered in modern Handan, Hebei) officer Zhang Lingzhao () (who had mutinied and expelled the military governor Liu Yanhao), Li Congke sent the general Fan Yanguang to attack the Tianxiong mutineers and commissioned Liu Churang as the director of supplies for the army north of the Yellow River, to aid Fan's campaign.
