Liu Yuru, the daughter of a cloth merchant, encountered the dilemma of her biological mother being seriously ill, her concubine's mother being unkind, and her father not paying attention to her. She had to be cautious and had been a model lady for more than ten years. Unexpectedly, her family arranged for her to marry Gu Jiusi, a well-known playboy in Yangzhou, who had longed for marriage. Gu Jiusi misunderstood that Liu Yuru married him for the purpose of clinging to the powerful, and sneered at her. Liu Yuru suddenly realized that her fate could not be tied to her marriage or to others, so she decided to follow Gu's mother to learn how to do business, so as to truly, independently and wonderfully realize her self-worth. Through hard work, Liu Yuru gradually became proficient in business, and in the process, she discovered Gu Jiusi's pure, kind, passionate and sincere side, and the two of them got closer and closer. However, at this time, the Yangzhou Jiedu envoy acted perversely, causing the people to be displaced, and the Gu family had to flee with their whole family. Gu Jiusi watched thousands of refugees grow up overnight. In order to end the chaos and let the people live in peace, Gu Jiusi started as a fast catcher, from the official to the Minister of the Ministry of Household Affairs, and worked with like-minded people to clean up the accumulated evils and reduce taxes and corvees. Liu Yuru built philanthropic halls internally and commercial exchanges externally, which made the supplies prosperous and the people healthy and healthy. The two wrote a prosperous story together.
