I personally think that a separate city is actually not very meaningful, to have people in this city, it will be meaningful. When one day in the future, in this city, there is a good oil (sister), there is the other half of the time, this city will become meaningful, and at that time even if there is no room, perhaps you will have a sense of belonging, because there are people here. My manager once told me that three years is a bump in the road in a city. He and some of his classmates came to Shanghai together after graduating from Beijing, but a lot of people left behind, and only a few stayed in Shanghai. The ones who stayed did so because they had a family or a significant other, or because they had established strong and solid relationships here and couldn't leave. Now the manager's chain of friends is almost all in Shanghai, and his family is also here, and he has taken his parents over, so he definitely won't leave Shanghai, and as for whether he has a sense of belonging, only the manager may know.
