Locals sit around a table as they have drinks at The Shelter nightclub, a former bomb shelter in Xuhui district, Shanghai June 2, 2012. The Shelter is one of a handful of former bomb shelters finding new life as commercial venues, ranging from clubs to clothing shops and even wine sellers. Hundreds of thousands of bomb shelters were built across China in the 1960s and 1970s to prepare for possible air raids from the then-Soviet Union amidst a souring relationship between the two communist countries.
