Wuzhishan, China

This "city" is more like a vast county, sprawling across over 1,100 square kilometers with a population of just 112,269 people. The reality is that Wuzhishan is an isolated, highland region, not the vibrant urban center you might expect. The local bureaucracy is a persistent headache, and the tropical climate can be draining.

If you're looking to escape the crowds and live close to nature, Wuzhishan could be a viable option. But for most, the remoteness and lack of amenities will make this county-sized "city" a tough sell.
