Hwang Ji-u Hwang Ji-u was born in Jeollanam-do in 1952. He studied Aesthetics at Seoul National University and Philosophy at Sogang University. Hwang Ji-u is a native of Haenam at the southernmost tip of the Korean Peninsula. He developed a deep interest in poetry while majoring in aesthetics and philosophy at college and graduate school. While active in literary circles in college, he participated in several anti-government protests and was forcefully drafted into military service. After being discharged from the army, he was expelled from university for his involvement in anti- government activities and was subjected to imprisonment and torture. The agonies and passions of his younger years are demonstrated in undertones throughout his poems, and artistically, if also painfully, sublimated against the background of the political conditions of his era. Hwang has worked as a Professor in the Department of Creative Writing, Hansin University.
