Her friend, Ignatius Ding, says of her: "She saw all of the dark side of human history. She was so sad and frustrated to see, day in and day out, what people could do to their fellow human beings. Those images hung over her all the time. Her room was like a shrine. This is where she had lived for the last ten years ever since I have known her. She cried a lot and was so depressed about the unfortunate past. Her study was just full of maps, pictures, photos. She posted all of it on the wall to keep track of the things she was writing. This is where she lived and it was like a shadow over her life all the time."
