Putian, China

This city of 3,210,714 people is known for its thriving counterfeit economy and domination of private healthcare - not the kind of place for those seeking a clean, by-the-books experience abroad. The local bureaucracy is a persistent headache, with the notoriously corrupt courts protecting the counterfeit trade. And while the cuisine featuring fresh seafood may tempt some, the climate here is unremarkable at best. Putian is best suited for those looking to make a quick buck in the shadows, not build a new life in the sun.
