Pizhou, China

With a population of over 1.4 million, Pizhou is a sprawling county-level city that offers little for the average expat. The region is relatively impoverished compared to the rest of Jiangsu Province, and bureaucratic hurdles are a persistent headache. While the city boasts the world's longest avenue of dawn redwood trees, stretching some 60 kilometers, the climate is not for the faint of heart. Ultimately, Pizhou is best suited for those with an iron constitution and a high tolerance for red tape.
