The Marquis of Dingyuan returns victorious from battle, only to bring back a mother and daughter. He intends to take one as his co-wife and marry the other to his heir. After twenty years of enduring humiliation, the Marchioness, Shen Wan, finally comes to her senses. She seeks out her daughter-in-law, Wen Zhihe, who has likewise been betrayed by her husband. The mother-in-law and daughter-in-law secretly join forces, inventory their dowries, and cleverly set a debt trap. On the day of the wedding banquet, they sever all ties with the Marquis's household and set off together for Jiangnan. Facing pursuit, commercial rivalries, and revenge from people in their past, the two women rely on their ingenuity and embroidery skills to establish Huixin Pavilion and open a school for girls. From women confined to the inner chambers, they gradually grow into businesswomen who control their own destinies, while paving a new path to independence for countless other women.
