Jiaozuo, China

With a population of 3,521,078, Jiaozuo is a sprawling industrial hub in Henan province. The city's economy has shifted away from its coal mining roots, but the bureaucratic headaches linger. Winters can be bitterly cold, with temperatures dipping as low as -22.4°C. While the tourism industry is growing, Jiaozuo remains a pragmatic choice for those seeking job opportunities in manufacturing or machinery - not an idyllic escape.
