Sang-nu, like his father, was from the Biryu-Bu of Goguryeo. His last name and ancestry is also unknown, but it is known that he and his father possessed a considerable amount of power over the nobles. Sang-Noo was the first Prime Minister to have inherited the position of Prime Minister from his father.
Very little is mentioned on this figure. This lack of mention in historical records may signify that Prime Minister Sang-nu was an excellent government official, or an incompetent one. This cannot be known. Sang-nu died in the year 294, during the 3rd year of the reign of King Bongsang, and was succeeded by Chang Jo-ri.
