My foolish Third Aunt is a kind-hearted country woman. An illness in her childhood left her with an intellectual disability, but she has a good heart. At home, her mother-in-law looks down on her, her sisters-in-law scorn her, and people in society laugh at her. Yet her kind nature and sincere personality bring her happiness. She gives birth to a clever son, who successfully gets into university, making everyone in the village see Third Aunt in a new light.
