Gui Er goes out to learn the craft of planting osmanthus flowers, and returns to the barren Osmanthus Village. The southern slope behind the village has been abandoned for years, with villagers only growing coarse grains and relying on heaven for food. Gui Er proposes planting osmanthus flowers, which is opposed by Uncle Gui, who believes there is no market or way to sell them. Gui Er insists on test-planting, and together with A Shi and Da Niu, clears the slope, cuts cuttings for seedling raising, prunes branches and thins buds. After going through pests and prolonged rain, they finally harvest osmanthus flowers, scenting tea, brewing wine, making pastries, and boiling paste, which opens up sales channels and leads the entire village to turn the barren slope into an osmanthus garden, filling the mountain village with the fragrance of osmanthus.
