Sorry for not replying for so long, we just returned to China and I'm totally jetlagged.
Germany is indeed beautiful, and I think with questions like these, everybody is tempted to name one's home - because that's of course the most beautiful area ever!

I can tell you two things that I found really valuable advice when I came first to China: Try to find something that occupies you, and start learning the language. It makes everything just much more easier, the locals really appreciate if somebody makes an effort, and in Germany, while most young people will speak English, that might not be the case with the older generation. Do and explore a lot, start with the must-sees: Berlin, Munich (don't go and visit the Oktoberfest if you're averse to large crowds), Hamburg. If you visit Hamburg, go and see one or more of the islands in the North Sea! Go to the Black Forest and say hello to Freiburg for me (where I went to university and is a much nicer city than Tübingen or Heidelberg), and while you're in the area, go to Strasbourg or Colmar in France or Basel or Zurich in Switzerland which are just a stone's throw away. I could go on and on!
When are you leaving and in which area will you be living?
