In a year of famine, the roads of Lotus Flower Village are cut off and food supplies are exhausted, leaving the elderly, the weak, the sick, and the disabled of the whole village on the verge of death. Yaya's small pouch accidentally awakens, and it can actually take her shuttling to the material-rich modern world. From then on, Yaya travels back and forth between the two worlds, trading mountain goods and handicraft items for rice, flour, cotton clothes, medicine, farm tools, and books, leading the whole village to clear wasteland and farm, weave baskets to generate income, learn to read and study, eat meat every meal, and also joining hands with the village chief to get rid of the man-eating villains in the back mountain, revitalizing a barren village waiting to die into a Peach Blossom Spring with abundant food, warm clothes, and a heritage of farming and reading, becoming the backbone and living lucky star held in the palms of everyone in the village.
