wow, it sounds like you've done alot already! Im impressed. China and Toyko are definitely on the top of my list of places of which i'd like to go to.
I love Germany i've already been to Berlin, infact i want to go back there again, but atfer i've visited other areas of Germany first!
yeah i was lucky as a child to get taken t fun and exciting placces on holiday often. then when i got into my late teens i started going places myself, certainly beats family holidays to spain that most of my friends went on. resort holidays arent really my thing.
since turning 18 ive been around the world, seeing loads of places, and spent a long time in australia. im now approaching my mid twenties and there arent many palces left to go. i will be honest i havent really explored south america fully, but caracas was so good i dont want to be dissapointed by rio or montevideo or any of the other places im recommended to go. would love to do something extreme like a everest climb or walk to the south pole. my ultimate dream is a moped/scooter tour around europe, maybe even the world lol.
go to hamburg or munich, great cities. oh and while you are in china you may as well go to hong kong, i still cant get my head around how big it is.
