**The core resume of the protagonist of "Golden Needles and Grass Mustard"**
1. **Lu Mingyuan (Male):**
* **Previous life:** Doctoral student in surgery at a top medical school (psychiatric trauma emergency).
* **This life (in the southern provincial capital in the 1960s): ** A high-ranking official with a sick and weak son. Trapped in the "golden cage" of the compound, he possesses complete and advanced medical knowledge but is restricted by his weak body, the limitations of the times and the shackles of his identity. He is eager to break through the wall and apply what he has learned.
2. **Lin Xiaocao (female):**
* **Previous life:** A master's degree student in medicine/public health at the same school (emphasis on grassroots practicality).
* **This life (Southern waterside village in the 1960s): ** An orphan girl from an extremely poor peasant family. Struggling against the shackles of hunger, labor and illiteracy, the sporadic knowledge of modern medicine and herbal medicine in her mind was her only weapon. Protecting the health of the family with local methods in the quagmire is the germ of the "barefoot doctor".
**Core Conflict:**
* **Golden Needle and Grass Mustard:** The ultimate contrast between the cloud (resources/knowledge) and the quagmire (survival/scarcity).
* **Shackles of the Times:** We face political storms, material deserts, and backward concepts.
* **Knowledge Dilemma:** The ivory tower pearl fell into the technological desert. The concept of sterility vs. Dirty environment; awareness of antibiotics vs. Herbal remedies.
* **Southern Brand:** The water network breeds the threat of schistosomiasis/malaria (which is difficult for Lu to understand, and Lin is trapped in it); moisture and heat are susceptible to wounds; rich medicinal herbs are Lin Xiaocao's vitality.
