A few years ago Supreme Leader Kim Jong Un visited the Chollima Tile Factory.
That day he made the rounds of the factory despite the sultry weather, praising the workers for their good workmanship and stressing the need to take measures for preventing damage from high temperature.
After seeing the workers packing the tiles for a while, he lifted a box of tiles weighing dozens of kilograms personally and asked the officials to calculate how much it would cost to automate the packing equipment.
The officials kept in their mind again his noble intention that nothing is more precious than the people, the essence of the country, and nothing is more sacred than their interests.
