The year of his birth and death, as proposed by Wangwaljeong of the Cheong(淸) dynasty, was around 1200 and 1264. However, through thorough examination of the records and context along with the relation between Wanghogo(王好古) and his teacher Igo(李古)'s works, the author finds that Wanghogo(王好古) was born around the year of 1230, and died around 1308.
