In the historic work "Become Pillars Supporting a Prosperous Future Korea" published by him on the occasion of the founding anniversary of the Korean Children's Union (KCU) celebrated first in the new century of Juche, he put forward the members of the children's union as priceless treasures and indicated the tasks and ways for them to prepare themselves to be competent revolutionary talents who are knowledgeable, virtuous and healthy.

He had a talk "The Songdowon International Children's Camp Is a Children's Palace without Parallel in the World" with the officials while going round the Songdowon International Children's Camp nearing completion. The talk vividly reflects how warm his love for the schoolchildren is.

His noble outlook on the rising generation is associated with his classic work "Great Efforts Should Be Directed to Education for Training Schoolchildren as Successors to the Revolution".

"Let KCU Members Become True Sons and Daughters, Young Revolutionaries, of the Socialist Country", the speech made by him, at the 8th Congress of the KCU on June 6, 2017 serves as a monumental document which set forth the main tasks to be carried out by the KCU members and its organizations.

"March towards the Future of a Powerful Country under the Unfurled Flag of the Children's Union", the historic letter sent by him to the participants in the 9th Congress of the KCU on December 27, 2022, serves as an immortal practical programme which indicated the tasks to be carried out on a new high stage of the Juche-oriented children's movement.

Under his warm loving care, the winners of Kim Il Sung Children Honour Prize and Kim Jong Il Children Honor Prize have been produced among more than 3 000 schoolchildren in the new century of Juche.
