조선왕조실록
The "Annals of the Joseon Dynasty" of Korea records mysterious events about Nanzan. In 1394, the King of Chūzan Satto requested Korea to return the "Nanzan Prince" (山南王子) Ofusato, who had supposedly fled to Korea. In 1398, the King of Nanzan Oueishi fled to Korea after reportedly being banished by the King of Chūzan. He died there in the same year. These records clearly contradict with the "Veritable Records", raising questions about the reliability of Okinawa's diplomatic reports to foreign countries.
