Of the Seongju Yi clan, his art name was Do-eun (陶隱). He studied under Mogeun Yi Saek and Poeun Jeong Mong-ju, and, renowned for his outstanding prose and poetry, was counted as one of the "Three Recluses" (Sam-eun) of late Goryeo.
He served as Ye-ui Sallang, Yemun Eunggyo, and Munha Sain, and traveled several times to Ming China as an envoy. His splendid prose is said to have amazed the founding emperor of Ming.
During the founding of Joseon, he was put to death in his place of exile by Jeong Do-jeon's faction. His literary collection Do-eun Seonsaeng Sijip (陶隱先生詩集) survives as a Treasure.
