When Lin Fan returns to his village to buy shrimp, he offers 22 yuan per jin at the pond. Zhao Qingfeng accuses him of taking advantage of familiar faces, citing the higher price of 26 yuan per jin in the county town. He Maosheng chooses to sell to settle his workers' wages, but Zhao Chunmei and others hold out for a higher price and buyers, only to discover after a cold wave that a high asking price does not guarantee a sale. Faced with payment demands, impersonated deliveries, and falsified inspection records, Lin Fan insists on inspecting the shrimp, keeping written records, and settling accounts, making each person accountable for their own actions. Later, he partners with He Maosheng, Sun Deshun, and He Xiaochuan to buy shrimp, dividing contributions, labor, and risks fairly. Over six months and 24 transactions, they prove that a lasting business depends on clear rules and shared responsibility.
