Chengxiang, China

With a population of 89,080, this small Chinese city is a far cry from the glittering metropolises that captivate most expats. The bureaucracy is a persistent headache, and the climate can be a grind. But if you're seeking an authentic, off-the-beaten-path experience, Chengxiang may be worth considering - just don't expect the comforts and conveniences of a global hub.
