Passengers go to the Nanchang railway station in eastern China in February 2014, at the end of the Chinese New Year holiday. In the past, it was often the only time of year that migrant workers were able to return home. Now, economic pressures on factories in coastal China has led to a reversal of a decades-long migration of workers from inland to the coast.
Over the past couple of decades, a river of labor poured out of China's interior to its coasts as hundreds of millions of people traded farm for factory. Most improved their lives, but they paid for it in other ways, leaving behind families for a sometimes lonely existence.
