Jiaxing, China

With a population of 5,400,868, Jiaxing is no quaint backwater. As a major industrial hub in eastern China, this prefecture-level city is a bustling commercial center, but one with a persistent bureaucratic headache. The Grand Canal of China runs through Jiaxing, making it an important transportation node, while the city is also a renowned textile and leather goods producer. However, the reliance on heavy industry means air quality can be a concern. Overall, Jiaxing offers ample economic opportunities, but the grind of city life may prove draining for those seeking a more laidback lifestyle.
