We didn't learn about this until early in the school semester, when students were auditioning to be volunteers at the 6th World Choir Games in Shaoxing. They started on July 15th, '10. Now I'm not sure that I would have extended my stay in China by 3 weeks JUST to include the Games, but I would have considered it.
It is surely a spectacular event, as China does not do anything by halves. I've not had any reports from students, but I see this story made it to CNN. You will enjoy the video - click on the link.http://english.cntv.cn/program/cultureexpress/20100717/101175.shtml
