In the autographic letter Kim Jong Un wrote that the Workers' Party of Korea embraces more closely and puts forward those who have a bruise of mind.

Mothers feel pain in mind and readily give their flesh and blood when their children suffer from pain and need them, and they are happy when they see their children rise to greatness and regard it as the biggest pleasure in their life, he wrote in the letter, adding that that's why the people call the WPK a mother party.

He wrote that he was also happy when he read the sentence describing her happiness at her eldest son Ri Chol Ho's admission to the WPK which he wished even in his dream.

Kim Jong Un continued that the party will help Ri Chol Ho so that he can do his work well, extending thanks to Rim for invariably trusting and relying on the party.

Rim sent a letter to Kim Jong Un on Dec. 1.

She wrote that even though she was Japanese, she was given the same treatment as Koreans and care was shown for her family on holidays and birthdays so that she would not feel loneliness. She added that during the Arduous March she was provided with satisfactory living conditions including salaries.

She also wrote that her eldest son Ri Chol Ho has a career of having committed a crime against the country for which he underwent legal punishment for three years. But he was put forward as an official of primary organization of the Kim Il Sung Socialist Youth League and was invited to attend the celebrations of the 60th anniversary of the League as a delegate. After graduating from Wonsan University of Agriculture, he has been working as a chief of a workteam, she added.

Shortly ago, he was admitted to the WPK on the 59th anniversary of President Kim Il Sung's field guidance to the Hamhung Sericulture Center under the Sericulture and Silk Guidance Bureau, she wrote.

She extended thanks to Marshal Kim Jong Un for the great loving care he has shown for her family and the great trust he put in it although he was busy looking after the state affairs.
