周德威
Subsequently, Liu Shouguang, hearing of Later Liang's defeat, was considering claiming imperial title himself. He sent messengers to Wang Rong and Wang Chuzhi, suggesting that they should honor him as "Shangfu" (尚父, meaning "imperial father," a highly honorary title that was rarely bestowed and only on highly honored senior officials). When Wang Rong informed this to Li Cunxu, Li Cunxu, pursuant to suggestions that his generals made that making Liu more arrogant would cause him to push himself into doom, signed a joint declaration with Wang Rong, Wang Chuzhi, as well as three other military governors under Li Cunxu (Li Cunxu's cousin Li Sizhao, Zhou Dewei, and Song Yao () honoring Liu as "Shangfu". Faced with this, the Later Liang emperor tried to keep Liu at least nominally a vassal by offering him the title of "Caifangshi" (). Liu thereafter nevertheless declared himself the Emperor of Yan.
