The charity granary in Qingwu Town is forcibly seized by Qian Shirong and his son using forged deeds and fake seals. Lu Shoucang, the granary's keeper, presents wooden plaques and account books to defend the truth. County magistrate Gu Changsong examines the deed and seal, exposing the fraud. A genuine deed is then retrieved from a stone chest, revealing Lu Shoucang's true identity as Lord Huai'an, the founder of the charity granary. Qian Shirong confesses and is brought to justice. The granary reopens, and the duty of protecting it passes from one person to the entire community.
