An autumn rain disrupts Kaoshan Tun's grain-selling plan; wet grain is rejected, villagers are anxious, and a grain dealer seizes the opportunity to lure them with high prices. Chen Qingchuan withstands the pressure, leading everyone to spread the grain out for drying, manage it in zones, conduct public testing, and use transparent accounting, turning a crisis into an opportunity to rebuild order. The villagers also transform from being in a rush to sell grain to taking the initiative to follow the rules and protect their harvest. The story demonstrates the power of rural mutual aid, honest management, and down-to-earth effort. When the grain is thoroughly dried and hearts are at ease, life truly has something to look forward to.
