Nianbo, China

The population of 240,949 may seem enticing, but life in this remote district of Qinghai comes with its challenges. Bureaucracy is a persistent headache, with Ledu District only recently being upgraded from a county in 2013. And the climate - well, let's just say the G6 Beijing–Lhasa Expressway is a lifeline in this harsh, high-altitude region.

For those seeking an authentic taste of rural China, Nianbo could be a rewarding experience. But make no mistake, it's no easy ride. This is a place for the hardy, self-reliant types who can navigate the red tape and bitter winters. The average city-dweller may find Nianbo a tough sell.
