Emperor Wen, Taizu of the Zhou (infant name Heita, a man of Wuchuan in Dai Commandery. His ancestry derived from the descendants of Emperor Yan. Yan was defeated by the Yellow Emperor, and his descendants fled to live in the northern wilds. There was a descendant named Puhui, who while hunting obtained a jade seal with three cords, inscribed: "Emperor's Seal." Puhui considered it bestowed by Heaven. In their vernacular, heavenly signs were called "yu," so they took it as their state title, Yuwen, and also as their surname. Later he deposed Qi and ascended the throne).
