Some 200 million farmers have left behind their families and fields to forge a living in China’s booming cities. The phenomenon has been described as the biggest internal migration in the history of the world.
Wu Dexiu is one of these migrants. She and her husband, Tang Qiqing, left their village in Anhui province nine years ago to make money in Shanghai. Their two daughters stayed behind and live with their grandparents.
