The Supreme Leader visited the Rungna People's Pleasure Park under construction in a day of May Juche 101 (2012) and instructed to arrange a recumbent place in the water park.

Saying that if the area around the water tank is covered with tiles or paving stones, there would be no place to lie after playing in water, he instructed to make a lawn or beach in the space between bathhouse and water tank.

He added that people would like to lie down on the beach better than lawn, stressing the need to make the beach with sand from Monggumpho.

Monggumpho, a scenic spot in the beach of Ryongyon County, South Hwanghae Province, is famous for its white sand.

Thanks to his love for the people, the famous beach of Monggumpho appeared at the Rungna Water Park.
