 Hae Buru led his followers and some of Bukbuyeo people to the city of Gaseopwon, a city near the Sea of Japan (East Korean Sea).In that same year, Hae Buru founded another Buyeo, which he named Dongbuyeo, due to its position east of Bukbuyeo.According to the Samguk Yusa, Aranbul, a minister of the Buyeo court, had a dream in which the Heavenly Emperor told him that Buyeo was to make way for the descendants of Heaven, and believing that the dream was a sort of omen, he advised his king Buru to move the capital.
