Jonathan Lindvall has been focusing intensively on China lately and recently gave a talk on the country here at our home. This talk, combined with the heavy emphasis on China in The World Is Flat, has heightened my awareness of this fascinating country.
The Great Wall is of course a classic symbol of China. (Wikipedia's article was a bit disappointing; the first time I've been disappointed by Wikipedia in a good while.) Anyway, I found this image and thought it very good and very appropriate.
