Never thought about someone would ask me this question? Basically I do not know the answer at all, the only thing I can think of is that most of Taiwanese is friendly and kind. However, I do not think this could be the main reason. I also do not consider the economic factor as a major reason either. It may be a reason to bring you to taiwan but not a reason to make you stay.
For my perspective, I only can explain what attract me to stay in where I live now. I never think I will go back to live in Taiwan. For a while, I even thought it would be a nightmare if I had to live in taiwan for the rest of my life. I think there is nothing wrong about Taiwan, it is probably I am from there, I do not find things happening around me are interesting at all. I met some people from France, Germany and Greece while living in UK. They all wanted to stay in UK after finishing their studies. I asked myself what the hell they want to stay in this bloody country for (Sorry for the English out there, the weather in UK is just far too bad). As I start wondering why they want to stay in UK and why I do not want live in my own country, I realize that it is the attraction of culture difference. So sometimes it probably does not matter where you actually choose to live as long as it adds some excitements and adventures in your life.
However, I do feel tired after living in a place for too long, so I consider the culture difference can only be a short term attraction. Currently I am living in bay area California. I love this place! It has everything I want to have expect everything is damn expensive down here. It is a place I can see myself to live for the rest of my life. So what is it special about California for me then? This is kind of question I know how to answer.
- The culture diversity, one of major things I want to have in my life. There are people from Taiwan, India, Europe, etc. around this area.
- Clean air and environment, not so crowded everywhere (opposite from Taiwan).
- Free and well-constructed public facilities, basketball courts, tennis courts, free Wi-Fi access (opposite from Europe).
- Great weather allows you to do a lot of outdoor activities
I may be able to understand why foreigners want to stay in Taiwan for a short period of time. However, it is hard to understand why someone stay for 10 or 20 years or even forever.
Oh…well… this may be a bit long and off topic… it is supposed to be a topic of why a foreign wants to live in Taiwan instead of why a Taiwanese does not want to live in Taiwan. : )
