Germany (Constance, Munich, Düsseldorf, Frankfurt am Main, Hamburg, Berlin, Leipzig, plus some other smaller cities, towns and villages.)
Switzerland (Zürich, Basel... etc; and only around the German-speaking regions)
France (Strasbourg for 1/2 day! :embarass: )
Belgium (Brussels and Brugge)
Great Britain (London, Manchester and Leeds... it was more a football trip.
I visited the grounds and saw some games!
China (only the very south of it: Guangzhou and somewhere near Zhongshan)
Singapore (only the airport!
Thailand (again, only the airport in Bangkok!
... not many places, but considering that my younger brothers and parents never have the chance to be anywhere out of Asia; and my father and I are the only ones who travelled by aeroplanes before. I feel lucky.
