In 1981, peasant woman Shen Xiulan and Dashan picked up 4-year-old Yaya in the mountains. Taking the opportunity, the mother-in-law made trouble and separated the three of them to live on their own. Disregarding public criticism, Xiulan treated Yaya like the apple of her eye. Yaya was naturally sharp-eyed and had a great memory. When following Xiulan up the mountain, she could always recognize the precious herbs Xiulan taught her, and even follow pheasant footprints to find nests of wild eggs. Relying on Yaya's "divine assistance", Xiulan pickled mountain goods and made medicinal meals, expanding her business to the county town. When Yaya's biological parents found out, they attempted to attach themselves using blood ties, but Xiulan stepped forward, making the son-preference biological parents watch their own declining household collapse in regret.
