Wow. As an aside, this BBC clip, below, talks about some town near Tibet that I've never heard of. It has a population of 10m. That's amazing. China's "other" towns, you know, the little ones we've never even heard of, are as large as our largest city. It reminds me of a story my old boss, Ted Stevens, used to tell (yeah, I worked for Stevens almost 20 years ago now, get over it). He tells how he had a meeting with the then-leader of China, Deng Xiaoping, and how Stevens asked what the population was of China. Deng said "around a billion, give or take 20%." Stevens replied, "Mr. Premiere, do you realize that your rounding error is the size of our entire population?" Deng replied, "yes, Senator, but do YOU?"
