Dongkan, China

With a population of just 72,789, Dongkan is hardly the bustling metropolis some might imagine. The reality is a small town where bureaucratic headaches and a punishing climate are persistent issues. Winters are brutally cold, with the record low reaching a bone-chilling -53°C. Summers offer little respite, as Dongkan bakes in temperatures that can exceed 40°C. Navigating this weather extremity is only half the battle - the local government is also notorious for its Byzantine red tape. Unless you're an adventurous soul willing to brave the elements and administrative hassles, Dongkan is best avoided.
