Because the early Jurchens had no written records, the story of Hanpu was first transmitted orally. According to the "History of Jin" (compiled in the 1340s), Hanpu arrived from Goryeo at the age of sixty and settled among the Jurchen Wanyan clan. Other sources claim that Hanpu was from Silla, the state that had ruled the Korean peninsula but was annexed by Goryeo in 935. The same story recounts that when Hanpu left Goryeo, his two brothers remained behind, one in Goryeo and one in the Balhae area. Because the Jurchens considered Hanpu to be the sixth-generation ancestor of Wanyan Wugunai (1021–1074), historians postulate that Hanpu lived in the early tenth century, when the Jurchens still consisted of independent tribes, or sometime between the founding of Goryeo in 918 and its destruction of Silla in 935.
