China 2009

This is my experience in Beijing, China in the Summer of 2009. If you came to this webpage first, it's better if you start from the beginning of the story.

[Ivory Counter]

At Xi'an

This is another interesting object called an Ivory Counter. It is a calculating device used by the ancient Chinese for arithmetic. The description card isn't very clear how it works. I gather it works in a similar manner like the abacus but I don't see how.
