Lan Wan masters her family's traditional wax-resist dyeing technique, an intangible cultural heritage, and returns to her hometown to establish a workshop that helps villagers increase their incomes. Ma Guixiang grows jealous and repeatedly spreads rumors and makes things difficult for her. She also profits from inferior chemical dyes that pollute the water supply. Lan carefully plans her moves, protects the natural dye-plant cultivation base, establishes a comprehensive traceability and anti-counterfeiting system, and gathers all the evidence needed to defend her rights through legal channels. Staying true to the spirit of traditional craftsmanship, she establishes fair profit-sharing rules and leads hardworking villagers in building an original batik brand. Their products reach international markets and secure overseas orders, allowing her to revitalize the entire village through honest craftsmanship and ingenuity.
