Meng Nanzhi pretends to be a poor girl who was exchanged by her stepmother in the 1970s. She is about to marry the stupid son of the captain's family as soon as she opens her eyes. She didn't cry or make a fuss, turned around and got into the pig pen of the production team, and earned a living from a leaky earth house to a small red brick building by relying on her unique skills of treating pigs. The cold-faced veteran next door always came to help build the wall and drive pigs away. Meng Nanzhi thought he was warm-hearted, but later she found out that he was holding half a piece of paper in his hand with the whereabouts of her biological mother.
