Shen Qinglan, a 51-year-old inheritor of the intangible cultural heritage of traditional snake-catching techniques, has spent years mastering ancient methods of processing snakes for medicinal use. She quietly cared for her family for years, but because her traditional skills were misunderstood, she eventually returned to her hometown alone. After rescuing an orphaned girl, she draws on her family's time-honored expertise to legally collect shed snake skins and extract snake venom under proper certification, researching medicinal raw materials. By chance, she meets Mr. Lin, who has devoted himself to the domestic pharmaceutical industry. When foreign companies offer exorbitant sums to buy out core medicinal-material technologies and competitors maliciously suppress her, she remains true to her original purpose, protects the domestic pharmaceutical supply chain, and refuses to let foreign technology hold the industry hostage. She establishes the standardized Yunling Snake Industry Base, creates jobs and increases incomes for local villagers, offers intangible cultural heritage classes, develops educational tourism projects, and revitalizes the rural economy.
