Chen Xi is my college classmate. I think if I hadn't met Shen Zhi, she would still be dragging three or two dark-skinned children in the small ditch where she was born, like her childhood companions, working at sunrise and resting at sunset, living the most ordinary life of a peasant woman. She herself could not have imagined that she would have traveled to several countries by the time she was thirty, all because of meeting Shen Zhi.
