Shuangfu, China

With just under 48,000 residents, Shuangfu is a small and relatively unknown Chinese city. The local religious movement, the "Three Grades of Servants," has drawn the ire of the government, which has denounced the group as an "illegal organization using the name of religion." Bureaucratic headaches are a persistent issue, as authorities crack down on unapproved spiritual activities. Overall, Shuangfu offers little to recommend it for the average foreign expat - this is a city best suited for those with a high tolerance for navigating China's complex religious and political landscape.
