Jiangmen, China

With a population of nearly 4.8 million, Jiangmen is a sprawling industrial hub in southern China's Pearl River Delta. The manufacturing sector dominates the local economy, though the city's plans to develop tourism have resulted in some environmental protections. Bureaucracy, however, remains a persistent headache - the city once faced public backlash over a proposed uranium processing plant. Overall, Jiangmen caters more to seasoned expats and adventurous investors than families seeking an easy relocation.
