Story behind Olympic dancing man's seal of approval

One year after Beijing won the rights to host the Games, organizers launched a contest in a bid to find a special logo for China's largest public event.

Seasoned advertising man, Guo Chunning, beat 1,300 other professionals with his entry - a powerful seal, which drew from history and reflected China's modern progress.

Seal cutting is a time-honored art among the literati and dates back to the Spring and Autumn Period (770-476 BC). The Chinese character for a seal is composed of two words: zhua, which means hand, and jie, a tally issued by a ruler to generals or envoys as credentials.
