This production was created with AI assistance. He Jiangyuan brings together traditional pickling skills, courses, markets, homestays, and jar painting to establish an educational tourism base featuring authentic production processes and transparent records. The team improves safety measures and batch management, but encounters problems when vegetables become damp and moldy. Abnormal test results lead to canceled contracts and investment pressure. He Jiangyuan publicly addresses the issue, while Wen Yanxian suspends the problematic batch. Zhao Shoutan discovers clues about moisture exposure during transportation in old notes, seals the raw materials, and supports refunds and rescheduling. The base upgrades its moisture-proof and traceability procedures, publicly discloses testing and rectification records, and rebuilds trust. It is shortlisted as an industry demonstration site, jar painting wins an award, and the integrated model of educational tourism, markets, and homestays takes shape.
