Jinzhong, China

This prefecture-level city in east central China is home to over 3.3 million people, but the reality of living here is far from idyllic. The harsh climate, with frigid winters and stifling summers, is just one challenge. Bureaucratic headaches are also a persistent problem, as the city was only recently upgraded from a county-level area. And while the historic architecture is touted as a cultural draw, the urban core is increasingly blending into the sprawling Taiyuan metro region. In short, Jinzhong is best suited for those hardy enough to withstand its practical difficulties.
