At the end of the Jiang Dynasty, the third daughter of the Shen family, Shen Yaoshu, was stuffed into a sedan chair to marry the sick second young master of the Gu family on behalf of her sister. On the wedding night, her husband Gu Jingxing coughed up blood and said, "You keep your spare room while I take care of my illness." Shen Yaoshu squeezed her wedding dress tightly, lowered her head and smiled. The next day when tea was served, the eldest sister-in-law threw her tea cup and said, "Does a concubine's daughter deserve to be in an official kiln?" The second sister-in-law falsely accused her of stealing the jade bracelet. Her mother-in-law slapped the table and asked her to kneel down in the ancestral hall. Shen Yaoshu knelt on the green bricks, pinching her fingertips into her palms - That night, she knocked on the door of her eldest sister-in-law's room and handed over an anonymous letter. Three days later, the eldest sister-in-law's private account was posted on the wall of the dining room. The second sister-in-law's bracelet was found from the bottom of her box, which became irrefutable evidence that she "directed and acted on her own". The mother-in-law was trembling with anger, but she held the newly brewed tea and smiled tamely: "My daughter-in-law wishes my mother well." No one knew that the words of the three hundred slaves in the back house had already woven into her web. It only took her seven days to go from being a frustrated concubine to being a feared opponent. But Gu Jingxing suddenly visited late at night, coughing and threw a piece of divorce paper to her: "The fiancée who studied abroad is back. You give up the throne." Shen Yaoshu clutched the piece of paper and raised her eyes to look at him: "Second Young Master, the rules in this house - you never have the final say."
