This work contains AI-assisted content, and its story is a fictional dramatization. After retiring from office, the elderly Marquis Xie Yannian relinquishes his authority and returns to his hometown. There, he faces a host of problems, including old disputes over riverside farmland, missing public grain allocated for dike construction, and illegally altered land deeds. Rather than using his noble title and authority to intimidate others, he insists on relying on evidence, contracts, account books, and on-site inspections. Working alongside the county magistrate, craftsmen, and villagers, he clarifies the facts, establishes joint management of the public granary, resolves the flood crisis, and uses his years of experience to assist his neighbors before completing the handover of responsibilities. He demonstrates that returning home does not mean stepping away from the world.
