At the age of 7, the little girl Lanxin collapsed from hunger at the village entrance and was saved by the lonely elderly woman Li Xinju, who gave her a steamed bun. The girl kowtowed and begged to be taken in; although the old woman had the heart, she refused with tears due to her inability to raise her. Lanxin followed all the way, taking care of the sick old woman with her frail body and warming the old woman's lonely heart with her sincere heart. Li Xinju, who had a sharp tongue and a tofu heart, finally let go of her concerns and adopted Lanxin. The old woman and the child depended on each other for survival, guarding and healing each other through the years, supporting a home with love, and writing the most touching grandparent-grandchild affection.
