Lin Wanxing, a girl from Loess Slope, lost both her parents when she was young. She was raised under the fence by her uncles and aunts as cattle and horses. She was despised and bullied by her fellow villagers. Even her marriage contract was maliciously tampered with, making her the laughing stock of the whole village. When she was falsely accused of stealing, beaten and driven away, and fell into a desperate situation with all her thoughts lost, she met Granny Su, an expert who lived in seclusion in the mountains by chance, and received her compassion and guidance. Not only did she learn the true skills of medicine, treatment, and housekeeping, but she was also inspired to change her character, lose her cowardice, and develop a tough edge. After that, Lin Wanxing was reborn from nirvana, exposing the evil deeds of her uncle and aunt step by step, clearing her own grievances, using her skills to save her neighbors, establishing a reputation, breaking worldly prejudices, turning from an orphan who could be bullied by everyone, to a strong person who is respected by others and can control her own life. In the end, she lived her own light, and gained warmth and redemption.
