Lucky Hajo, you're in Denmark! I was thinking about this, when the time is right, bring my love over on a tourist visa and get married in Denmark, it's really easy and saves a lot of paperwork as opposed to marriage in China ...
Another idea for free calling, I use a Windows mobile phone, so when in China or elsewhere in the world, I either use one of my SIP accounts to call home, or Skype out depending on how friendly the wifi network is, Skype always works as it doesn't use any particular protocol as opposed to SIP. There are so many free Wlans everywhere, even in Cn. I always get a China mobile SIM card, I think it's 100RMB and you can call ages on it, at least internally, and I tell people who need to know how to reach me the number.
I also have Sip phones at home and at work and there are many low cost providers to China, here in France, calling China and another 150 countries is actually free, or should I say included in the DSL subscription depending on the provider.
