Su Wanzhao was abandoned by her mother-in-law Li because she had not given birth to a son in three years. She returned to her natal Sujia Village with her three-year-old daughter Xiaotao. However, her brother Su Daqiang drove her to a broken house outside the village on the grounds that "the married daughter threw water". Relying on the cooking skills and knowledge of herbal medicine taught by her grandmother, she planted mugwort, mint and other medicinal herbs in the wasteland next to the dilapidated house, and used the wild vegetables from the back mountains to make medicinal meals and sell them to passing merchants. By chance, he rescued the exiled scholar Shen Huaijin, and the two worked together to improve the soil and expand herbal cultivation, and their medicinal diet business grew bigger and bigger. When her former husband's family saw her fortune and came to ask for reconciliation, she slapped her in the face with a divorce letter. When her mother's brother came to ask for money, she used a deed to prove the ownership of the land, causing him to leave in despair. In the end, Shen Huaijin was cleared of wrongdoing and reinstated. The two opened a big restaurant in the village and lived a stable and happy life.
