Laojunmiao, China

With a population of 137,736, Laojunmiao is no tourist haven. The oil town's bureaucratic headaches and stark natural conditions make it a tough sell for all but the most intrepid expats. While the region boasts abundant mineral resources, including significant nickel deposits, the locals endure a heavy tax burden and persistent environmental challenges like desertification. For those seeking an off-the-beaten-path experience, Laojunmiao may hold some appeal, but it's hardly a destination for the faint of heart.
