Lin Xiaoyou, a doctor of modern agriculture, accidentally traveled to the northern countryside in 1953 and became a newly widowed young daughter-in-law of a poor peasant family. Facing the complex environment of famine, the end of land reform, and the emergence of cooperatives, she relied on modern knowledge to lead the villagers to improve farm tools and promote planting techniques, while balancing personal emotions and collective interests, writing a chapter of struggle in the tide of the times.
