Since then, the day comes to be a significant occasion for KCU members along with the parental loving care shown by the peerlessly great men for them.

On June 6, 1961, Kim Il Sung personally attended the Joint National Meeting of the Korean Children's Union Organizations held on the occasion of its 15th founding anniversary and enjoyed the whole day together with schoolchildren, saying that June 6 is not only a big holiday for KCU members but also a joyous occasion for adults.

And he sent a congratulatory message to the participants in the 5th KCU Congress and had a photo session with them on June 6, 1994, the last year of his life.

Leader Kim Jong Il took measures to organize the splendid celebrations of the 20th founding anniversary of the KCU, personally examined the schedule of celebrations and gave instructions for shooting fireworks in Pyongyang on June 6, 1996.

The respected Supreme Leader Kim Jong Un, who carries on the noble outlook of Kim Il Sung and Kim Jong Il on the rising generations, made a congratulatory speech at the Joint National Meeting of the KCU Organizations for celebrating its 66th founding anniversary and enjoyed an art performance together with over 20,000 participants.

He also attended the 7th KCU Congress on June 6, 2013 and visited Mangyongdae Revolutionary School to congratulate its students on June 6, 2014.
