Loushanguan, China

The population of 80,344 might sound sizable, but the reality is that Loushanguan is a remote mountain town with a notoriously difficult pass to traverse. Crossing the Loushan Pass, with its long, winding path and three high peaks, is a strategic challenge that has inspired poets like Mao Zedong, but for the average traveler, it's a persistent headache.

Bureaucracy is another hurdle, as Loushanguan sits in a contested region that saw fierce battles between the Red Army and Kuomintang forces during the Long March. While the town's history is fascinating, those seeking an easy, carefree relocation abroad would be better off looking elsewhere.

Loushanguan may appeal to the adventurous few drawn to its rugged landscape and literary legacy, but for most, the combination of logistical hassles and security concerns makes it a poor choice as a long-term destination.
