She had to go out to work in order to pay off the debt and medical expenses. One day, when Yi Wang took his 8-year-old daughter Yifei to buy a birthday gift, she saw him. Yi Fei believed that Ye Xuan was a doll and clamored for Yiwan to buy it for him. Yi Wang, who always obeyed his daughter's advice, discussed it with Ye Xuan. In the end, Ye Xuan became Yi Fei's "baby" by working part-time.
One day three months later, Yi Fei went out to play alone. While crossing the road, a car hit her.
