It was said that Ren Huan was handsome in appearance and capable in speaking. There had been an occasion when false accusations were laid against Li Sizhao to Li Keyong's son and successor Li Cunxu (who then ruled the domain as the Prince of Jin after Tang's fall). Whenever Ren served as emissary from Li Sizhao to Li Cunxu's court, he would explain on Li Sizhao's behalf, to keep the communications open and friendly. When Ren's mother died, Li Cunxu, in the name of the emperor of the fallen Tang, recalled him to governmental service, serving as Li Sizhao's judicial officer in his role as governor of Zhaoyi.
