One day in May Juche 40 (1951) President
The President instructed him that the KPA General Staff should take a prompt measure to recover their health and to improve the supply work for them. And he thought for a while and said that rest houses for soldiers should be set up at the war fronts.
He continued that combatants would be able to restore their energies better if they were sent to the rest houses and served nutritional foods for a few days after hard battles.
Thus, the war front rest houses never to be seen in the war histories of the world came into being.
