She, who was born into a poor peasant's family before the liberation of Korea, had faithfully worked at the Munphyong Refinery as an innovator for decades out of her desire to repay President Kim Il Sung and Chairman Kim Jong Il for liberating Korea and making her enjoy a worthwhile life.

She brought her descendants up to be soldiers and socialist builders.

Since becoming a pensioner, she has done the patriotic work conducive to the economic life of the country.

She likes soybean dishes and keeps herself civilized and optimistic, cultivating kitchen garden.
