It is estimated that there are around 60 million left-behind children in China. According to the data from the Institute of Psychology at Chinese Academy of Sciences, 34% of these left-behind children have suicidal thoughts, 9% of them have attempted suicide, and 70% of them have some kind of psychological or mental problem. In March and April of 2015, freelance photographer Liu Feiyue went to Longnan, Gansu Province twice for his visual profile series on left-behind children. CDB has re-published the photos and translated their captions with the permission of the photographer. We divided the photos into three series. This series on left-behind children – called “Childhoods of the Left-behind children” (留守的童年) – was originally featured on Tencent News (link here).
