Weng Fen belongs to a generation of Chinese photographers whose principal subject is a China in the throes of physical, social, economic, and political change. His "Sitting on the Wall" series focuses on the elevated urbanism of cities such as Hai-kou, Shanghai, and Shenzhen. Many of these photographs feature schoolgirls with their backs to the camera, perched on a wall or precipice, staring at the landscape-adolescent figures on the threshold of personal transition looking out onto a landscape and a culture at a similarly transformational moment.
