In ancient times, the Lin family of a poor rural village struggled to make ends meet, their thin fields yielding barely enough to keep hunger at bay. The eldest son, Lin Yan, knew his herbs well and discovered that the back hills were covered in medicinal plants he could sell. He took his younger brother up the mountain to gather them, and their first sale brought in money and grain—enough for the whole family to eat their fill. At first the villagers didn't understand and even mocked him, but Lin Yan paid them no mind and eagerly taught his neighbors how to identify and harvest the herbs. He struck a long-term supply deal with the town's apothecary, and his income climbed steadily. One by one, the family added household goods, repaired their crumbling thatched cottage, and put their fields in order, balancing farming with herb gathering. Once they were better off, the Lins never forgot to do good—they helped the village's elderly and childless, and inspired the whole village to earn more by gathering herbs. The community's spirit turned toward kindness, and everyone worked hard and honestly.
