Included in the exhibits popular among visitors were programs presented by teenage coders of the Hamhung Schoolchildren's Hall in South Hamgyong Province.

The programs are considered to be conducive to cognitive development of schoolchildren in different subjects like foreign language, mathematics and physics.

O Song Bok, a teacher of Ryusong Primary School in Central District, Pyongyang, said that those programs coded by the teenagers make everyone take an optimistic view of the future of the country which is growing stronger by dint of science and technology.
