Her affection for the Mangyongdae revolutionary family members helped them grow up to be true revolutionaries with love for the country and the nation.

After the demise of Kim Hyong Jik, an indomitable revolutionary fighter, she said to President Kim Il Sung: "Jungson (grandson), you will have to take over the burden your father was carrying now. You must pick up the cause where he left off and win back the country, come what may. You may have no chance to take care of me or your mother, as is your filial duty, but you must give yourself heart and soul to the cause of Korea's independence."

He was deeply impressed by her words and gained great strength therefrom.

It was her temperament and spirit not to submit to any coercion and injustice.

When the Japanese imperialists forced Koreans to change their names to Japanese ones, she did not respond to the demand but resisted stubbornly their pernicious colonial rule, thus demonstrating her ardent patriotism.

She held fast to the principles as the mother and grandmother of great revolutionaries when the Japanese imperialists made desperate efforts to attain their heinous aim while concentrating all "punitive" forces on the headquarters of the Korean People's Revolutionary Army and launching "surrender campaign."

She said, "You may take me along by force, but I won't help you. Instead, I will look around Mt. Paektu and Manchuria where my grandson is fighting against you, just to see who will be the winner."

Whenever the enemy poked her in the back with a rifle butt to make her call out her grandson's name, she retorted, "I don't know how to blabber wild nonsense like that. Anyway, do you think you can kill me and get off scot-free? Go ahead, kill me if you want to end up with my grandson's bullet in your skulls!"

Finally giving up on their attempts, the enemies who mobilized her to the "surrender campaign" were compelled to send her back to Mangyongdae.

She was not a professional revolutionary. And she neither attended school nor received any revolutionary education in an organization. But she strongly resisted the enemies and behaved sturdily.

President Kim Il Sung writes about it in his reminiscences that the tradition of the Mangyongdae family and the revolution turned her into such a heroic woman.

Even after the liberation of the country, she led a simple and upright life till the last moments of her life though she was the grandmother of the head of state.
