In October 2000, Madeleine Albright, secretary of State of the United States, visited the DPRK.
At a banquet attended by Chairman Kim Jong Il, she set a puzzle to the participants.
How was it possible to make 16 with your ten fingers?
A deep silence fell over the banquet hall.
The silence was broken by Kim Jong Il, who came up with the solution. Saying that it was quite easy, he extended his ten fingers with both thumbs overlapped to form a cross, expressing 4×4.
All looked at him in admiration.
Albright was the first to clap her hands.
