Gwanggaeto Stele
According to legend, Jumong is the child of Haemosu and Yuhwa, daughter of Habaek, the god of the Amnok River or, according to an alternative interpretation, the sun god Haebak (). However, Hae Mo-su does not appear in older Chinese records or on the Gwanggaeto Stele that describe Goguryeo's founding. It is thought that Goguryeo integrated the founding legend of Buyeo after the former conquered the latter.
