Baoji, China

With a population of over 3.3 million, Baoji is no sleepy backwater. This industrial powerhouse in western China controls a strategic mountain pass and has been a major transport hub for centuries. However, newcomers should brace for some bureaucratic headaches - the city's metro system is still in the planning stages, and the climate can be harsh, with the Qin Mountains surrounding the city on three sides.

Overall, Baoji is best suited for those seeking an authentic Chinese industrial experience, rather than the glitz and glamour of the east coast megacities. The city's long history and cultural sites provide plenty to explore, but day-to-day life is likely to involve more red tape than scenic vistas.
