On a holiday in October Juche 55(1966) President Kim Il Sung visited the Educational Books Printing Plant.
While looking round a production building, he saw textbooks in sacks piled up in the corridor.
After asking why the textbooks were put in the sacks, he said that textbooks should be wrapped in packing sheets like corrugated or Kraft papers, not in sacks, adding only then can the textbooks be sent undamaged to students.
Many people saw and handled the textbooks in sacks, but no one ever thought that it would damage the textbooks.
Only the President who cherished warm love for the coming generations was much concerned on the problem to which all others were indifferent.
