Rocky, I think you may have a slightly romanticized image of Sweden! Haha. Sweden is great in many aspects but it's not all goody gumdrops.
It's one thing to like ones country. But when to decide where to live there is more to it than that. Personally I don't have many friends left here, several have moved abroad and others have decided to stay in their home villages where we grew up. Since my family was reduced to half after an accident, I've felt an even stronger urge to move away. And as it happens, I like Asian women!
So for me there might be an escape tendency to it as well. I'm looking for a place where the bad memories do not occur. But China is special, I experienced it the first time. I thought it was just because I was away from home and that I needed to get away. But every time I arrive in China, it's the same feeling. The feeling of "coming home". It's really strange. Thailand is great but I never get the same feeling there. Or anywhere else. I'm still in my late 20's, if I move to China in a few years and don't like it, I guess I can move back again and start over.
Peter, the 6 months-6 months plan seems perfect! I wish you good luck with that, to experience the Swedish summer and not the winter must be amazing. The get the best from two worlds. :-)
