南京大屠殺
The subject of the Nanking Massacre entered Chang's life again almost two decades later when she learned of producers who had completed documentary films about it. One of the producers was Shao Tzuping, who helped produce "Magee's Testament", a film that contains footage of the Nanking Massacre itself, shot by the missionary John Magee. The other producer was Nancy Tong, who, together with Christine Choy, produced and co-directed "In The Name of the Emperor", a film containing a series of interviews with Chinese, American, and Japanese citizens. Chang began talking to Shao and Tong, and soon she was connected to a network of activists who felt the need to document and publicize the Nanking Massacre.
