Woodcutter Lu Jingchuan meets a mysterious woman who helps him, and he uses her predictions to become the prime minister. His first wife, Su Wan, killed pigs and sheep and worked hard to raise money for him to study. However, after he became a noble man, she saw that he wanted to bring his sister-in-law Liu Yue'er and her daughter into the palace. Liu Yue'er once disliked the poor and loved the rich, hooked up with foreign men, and even killed Lu Jingchuan's younger brother. Su Wan was angry and blocked her with a butcher knife. Lu Jingchuan did not miss the old relationship and scolded Su Wan for being vulgar, preferring Liu Yue'er's "gentle and virtuous" character, and even wanted to divorce his wife. Su Wan exposed Liu Yue'er's true face and her efforts in public, but she couldn't get her husband to change his mind. In the end, she broke the love affair in anger, resolutely reconciled with Lu Jingchuan, and left with her daughter.
