Two fraudsters posing as alchemists came to the remote Qingxi Village, exploiting the villagers' lack of awareness to swindle them out of money and valuables. Intelligent village girl Zhang Ruoyin teamed up with her neighbors to carefully gather evidence, and with the assistance of the local village security, exposed the scam and recovered the defrauded property. The fraudsters repented and accepted labor punishment. The villagers established a school, popularized knowledge, reclaimed wasteland for weaving, broke superstitions, and jointly built a new, hardworking, and kind-hearted countryside.
