Again, to answer the question about the standard of living, we often have to refer to or rely on Chinese statistics for economic growth and development. By those measures, it's quite clear that economic standards of living have risen across the board.
Our reporting would suggest that this economic development over the last 30 years, or even less, has been unequally distributed. As I mentioned, there's a bit of a closed economic loop that happens there. I think, related to that, there's the issue of migration, the inward movement. Yes, I think even the Chinese population statistics would acknowledge that there has been an influx of Chinese citizens from other regions of the country, primarily ethnic Hans, moving into Tibet.
It's also difficult to determine exactly the numbers, too, because there's been a history of even government officials spending part of their time—their summers—in Tibet, in Lhasa, and then moving and having their families reside in Chengdu, in Sichuan, in the plains, where it's a completely different climate and situation. It's difficult to determine, according to the statistics, exactly how much in-migration there has been.
