A female teacher at the affiliated elementary school, around twenty-five years old. She is the mother of Yingying, who was conceived after Cheng Li assaulted her three years ago. She kept the child secret from her parents initially but later developed feelings for her daughter. She rejected Cheng Li's attempts to reconnect and refused his monetary compensation. She has a strong motive to kill Cheng Li, expressing relief at his death. She is described as plain-looking now but was once fashionable, as seen in an old photograph.
