It's not just because it's "nice". I am very fascinated by the silk road but the problem ist the temperature in January. That's why I asked if you have other suggestion to visit in China.
I know that even if I fly China Southern I may not credit the miles on Air France/KLM but they have the best price and the best connections as well.
Ctrip is a great site. I didn't know it. I found a good fare there (a little bit more expensive than the one on China Southern website).
Thanks for the replies!

Sao Paulo ist a great city. But the coast of Sao Paulo is even more beautiful if you do like beaches =)
