I don't think you understand the pride each participant of this opening ceremony has. This is not about claiming personal fame, this is about collectively showcasing the best of what we have to offer the world. Even the artists who lost their bids to Zhang Yimou as director of the show later selflessly worked with Zhang as assistants. I don't think they will get too much credit for it, they did it because they want to be part of something great. If you don't understand that, you will never understand why China came such a long way in such a short time.
