Kaitong, China

With a population of 62,537, Kaitong is no quaint village. The tax burden is heavy and bureaucracy a persistent headache. While the city's ancient cash coins may fascinate numismatists, the average expat is more likely to be frustrated by the opaque regulations governing day-to-day life. Kaitong is best suited for those with a high tolerance for administrative red tape and a penchant for uncovering obscure historical artefacts.
