Zhangjiagang, China

With a population of over 1.4 million, Zhangjiagang is a sprawling industrial hub, not the quaint riverside town its scenic location might suggest. The per capita GDP of $29,300 reflects the city's prosperity, but its rapid growth has come at a cost - many tributaries have been contaminated by chemical factories in the suburbs. Bureaucracy is a persistent headache, and the local dialect can be a barrier for outsiders. Overall, Zhangjiagang is a pragmatic choice for those seeking economic opportunities, but it lacks the charm and livability of other expat destinations in China.
