On November 10 Juche 35(1946), President Kim Il Sung visited the Sariwon Textile Mill, busy as he was with state affairs.
As he looked round different production processes, he reached a floss-unreeling workshop which was filled with the bits of floss.
Declining the mask offered by the manager of the mill, he said anxiously that as the workers were working in the dusty place, a measure should be taken to frequently replace their masks with new ones.
And as he went round the dust-covered workshop, he asked the workers whether the job was hard and how many hours they worked a day. Deeply moved by his noble traits, the manager felt guilty as he had never entered the workplace without mask.
