Provincial capital expert Lin Yuqing took her father to Daniu Village for three years of free clinic services, charging no consultation fees and only charging cost prices for medicine, once revered by villagers as a living Bodhisattva. Villager Liu Wei brought unverified low-priced medicine for price comparison, inciting the crowd to block the door and force her to refund thirty thousand in price differences. Lin Yuqing left the health records and chose to leave. When heavy snow sealed the mountains, she still entered the mountain as a healer to save people. Later, Liu Wei gullibly believed a free clinic scam, causing losses to the villagers. After going through twists and turns, Lin Yuqing no longer fought alone, driving multiple villages to establish long-term mobile clinic and chronic disease management systems.
