Sin Kwangsu

Sin Kwangsu (; 1712–1775) was a poet of the late Joseon Dynasty. Living in the time of King Yeongjo, he was unable to attain a position of rank because his family was aligned with the Southerners faction. He married the daughter of Yun Tusŏ and became associated with Silhak. At 39, Sin finally passed the higher exam of the kwagŏ and was sent to Jeju Island as an official. He wrote a description of the island. His famed words from later life include the Kwan sang yung ma and Kwansŏ akbu .
