高行周
The new Later Zhou emperor formally took the throne in spring 951, and most Later Han military governors formally submitted to him as emperor, including Gao Xingzhou and Murong Yanchao. (The main exception was Liu Chong the military governor of Hedong, the younger brother of Later Han's Emperor Gaozu (and father to Liu Yun, who was executed by Later Zhou), who declared himself the new emperor of Later Han, but whose state was subsequently known historically as Northern Han and not traditionally considered part of Later Han's history.) Murong, however, was apprehensive under Emperor Taizu due to his status as Emperor Gaozu's half-brother, so he gathered soldiers and food, considering a rebellion, and was in communications with Northern Han, Liao, and Southern Tang. To try to assuage concerns that Emperor Taizu may have about him, he repeatedly sent his attendant Zheng Lin () to Kaifeng to claim loyalty and to also spy on the imperial court, while submitting letters that he claimed were written by Gao in which the writer defamed the Later Zhou imperial government and offered an alliance with Murong. Emperor Taizu, however, did not believe that Gao had written these letters, and sent the letters to Gao. Gao responded by submitting a petition thanking the new emperor. Murong subsequently rebelled against Later Zhou, but his rebellion was put down by summer 952.
