Lin Yue, raising three sons alone in a rural village, encounters a lost little girl while digging for wild vegetables on the mountain, takes her in, and names her Xiaobao. This child seems exceptionally fortunate; ever since her arrival, the Lin family's circumstances have steadily improved. Facing everyday frictions, Lin Yue spends her days solidly with the children, living a stable and smooth life. Later, the village suffers a severe drought with crops generally failing, yet only the Lin family has an abundant water supply and crops growing in prime condition. Xiaobao not only helps take care of the household but also cultivates rare medicinal herbs alongside the villagers, turning the village into a renowned medicinal herb production hub and becoming a beloved little mascot for the whole village.
