Ren Huan
Ren Huan became a chancellor in Li Siyuan's new administration. As he admired Li Yu, he repeatedly recommended Li Yu as a chancellor as well to Li Siyuan's powerful chief of staff An Chonghui. However, An's ally Kong Xun was then trying to plant his allies in the administration, and at Kong's recommendation, Cui Xie was made a chancellor instead of Li Yu. Shortly after, Li Yu was put in charge of the imperial examinations, and at a later point made both the deputy minister of defense (兵部侍郎, "Bingbu Shilang") and chief imperial scholar (翰林學士承旨, "Hanlin Xueshi Chengzhi"). Early in Li Siyuan's "Changxing" era (930-933), Li Yu was removed from those posts and given the largely ceremonial post of minister of worship (太常卿, "Taichang Qing"). However, shortly after, then-chancellor Zhao Feng was removed from his chancellor post, and Li Yu was made "Zhongshu Shilang" (中書侍郎, deputy head of the examination bureau) and given the designation "Tong Zhongshu Menxia Pingzhangshi" (), making him a chancellor, replacing Zhao. He was also later given the additional title of grand scholar at Jixian Hall ().
