Eighteen years of parental care cannot compete with a single university admission letter. Lin Xiuzhi studies hard and earns a place at university, but her adoptive mother, who favors boys over girls, publicly tears up her admission letter just to save money for her son's wedding. Eighteen years of family affection come to an abrupt end. Enduring the whole village's ridicule, Xiuzhi grits her teeth and retakes the entrance exam, becoming the county's top liberal arts student, only to end up studying animal husbandry by a twist of fate. After graduation, she gives up a secure government job in the provincial capital and returns to her village to establish a sheep farm. Despite her father-in-law's malicious poisoning and relentless rumors, her husband, Chen Jianjun, and her companions give her their full support. Together, they build a modern standardized sheep farm from the ruins and lead their neighbors onto the road to prosperity. Along the way, a secret about her birth that has been buried for twenty-two years finally comes to light.
