What “cosen” means
WikipediaJoseon, officially Great Joseon State, was a dynastic kingdom of Korea that existed for 505 years. It was founded by Taejo of Joseon in 1392 and replaced by the Korean Empire in 1897. The kingdom was founded after the overthrow of Goryeo in what is today the city of Kaesong. In 1393, Korea was retitled and the capital was moved to modern-day Seoul. The kingdom's northernmost borders were expanded to the natural boundaries at the rivers of Amnok and Tuman through the subjugation of the Jurchens.
