He was entrusted by his cousin as the commander of the Pyongyang Regional Military Command.

Biography
Wang Sing-nyom was the son of Wang P'yŏng-dal. In 918, he was appointed as the commander of the Pyongyang Regional Military Command. He would be promoted to junior vice councilor.

After the death of his cousin, King Taejo, Wang Sing-nyom partnered with his nephews, Wang Yo and Wang So, in the struggles for succession. In 945, Wang Kyu, a father-in-law of both Taejo and the then reigning King Hyejong, attempted to enthrone his maternal grandson, Prince Gwangjuwon. Military forces from Pyongyang under Wang Sing-nyom's command were able to stop and eliminate Wang Kyu. He later died in February 7, 949 and was posthumously honoured with the name of Wichŏng.
