Born in Kyongju, North Kyongsang Province of south Korea, he longed for learning from his childhood.

He hoped for a teacher. His parents made every possible effort to provide him with an opportunity to learn. He also delivered newspapers but only went to night training school.

His hope remained a dream in the south Korean society where money decides everything. It was not until he came to the embrace of the DPRK after the war that his dream came true.

He graduated from Kim Il Sung University under the care of the country and became its teacher.

He took part in the struggle for the reunification of the country during which he was imprisoned in south Korea for decades. He defended his faith to the last in prison, looking far into the future when he would become a teacher of a reunified country. He finally came back to the fold of the socialist country.

He suffered from heart disease but recovered his health under the care of the state.

He authored several textbooks and books including "Chinese Study through Conversation" and "English Everyday Life Conversation" conducive to the education of the rising generation.

He presented "World Origins and Commonsense Dictionary" to the State Book Exhibition for celebrating the 65th anniversary of the Workers' Party of Korea last year. He was awarded the DPRK doctorate in science of history shortly ago.
