Du Xiaoqin returns to her hometown to build a house, confidently assigning the workers and hoping to save the wages of hiring Old Zhou, an experienced master builder. But once construction begins, problems keep piling up: the equipment gets moved, relatives show up in droves to help, material costs exceed the budget, and the ground beams bulge out of their formwork and encroach on the neighbor's property. The construction site falls into an impossible predicament. Comparing Old Zhou's seasoned experience, careful advance planning, and contingency preparations with the chaos unfolding on-site, Du Xiaoqin finally realizes that a schedule on paper cannot control the uncertainties of reality. Building a house is not just about calculating materials; it also requires understanding human relationships and the realities of village life.
