At a night General Secretary Kim Jong Il set forth a bold goal of the 70-day campaign. Foreseeing that the cargo shipment would increase, he instructed an official by phone that he should take measures for it beforehand.

He asked him how many derrick cranes for port could be made. Saying that 10 derrick cranes were too small to do work, he stressed that about 50 derrick cranes should be manufactured in a month at any cost.

Surprised by the exorbitant figure, the official did not speak for a moment with the handset in his hand.

After fathoming his mind, the leader said to the following effect: I thought you are a man with grit as you are an official of working class background but you seem to be not that kind of people. A revolutionary should be broad-minded. Only then, can he go through difficulties without hesitation to make a breakthrough and vigorously advance no matter what difficult work the Party and the revolution may be faced with.

He encouraged the official to carry out the task in a bold way as he would positively back it, saying that the mental preparation was important in any work.

Under the bold and energetic leadership of Kim Jong Il about 50 derrick cranes were installed in major ports in east and west seas of the country in a month.
