In the 1970s, ten-year-old Nan Nan suffered a sudden change: her mother fell off a cliff and was seriously injured. Her grandmother forced her to sign a deed for a meager reward and sent her to Wang Hu's family as a child bride. The mother tried her best to protect her daughter, but was injured by Wang Hu and passed away. Before her death, she gave Nannan a seven-leaf and one-branch silver hairpin, a Miao medical token, and asked her to flee to Miaoling to join her grandmother.
Nan Nan fainted from hunger during her escape and was rescued by her grandmother, a reclusive Miao doctor. Wang Hu led people to chase him, but his grandmother used Miao medical skills to force everyone back. From then on, Nan Nan followed her grandmother to learn the essence of Miao medicine's "Two Cardinal Principles and Five Classics" and "Treatment of Cold Diseases and Hot Heat", but she was repeatedly harassed by Wang Hu. Nan Nan's grandmother was seriously injured in order to protect her. Nan Nan made a vow to learn Miao medicine well to protect the people around her, and to pass on the skills of Miao medicine.
Purpose: Nannan sticks to her original aspiration in the face of adversity and becomes an apprentice to learn Miao medicine. The path of growth and counterattack shows the unique charm of Miao medicine culture, interprets the benevolent love and perseverance of doctors, and writes a moving chapter of the inheritance and development of Miao medicine.
