Su Jinli, the concubine of the Marquis of Jing'an, married into the Shen family of merchants as her eldest daughter-in-law. She thought she would be able to live a stable life, but she encountered a partial mother-in-law, greedy uncles and sisters, and a cowardly husband. The Shen family's shop was eaten away by side branches until it was nothing but an empty shell. Without a golden finger, she only relied on a pair of discerning eyes, a certain amount of ruthlessness, and a certain amount of calculation to start from revitalizing a silk and satin shop that was on the verge of bankruptcy. She exposed her uncle and sister-in-law's conspiracy to misappropriate money, forced out her mother-in-law's selfish selfishness, and woke up her wavering husband. She entered the business world as a woman, fought against profiteers, broke monopolies, and built trade routes. She brought the Shen family back from the brink of ruin and took control of the family step by step. When the relatives of the Hou family tried to cling to blood, she tore up their hypocritical masks with her backhand and made all those who had bullied her surrender. This is a business war without gunpowder, and it is also a family ethics drama of gratification and grudges. Su Jinli uses her own skills to carve out a unique path for her to be the owner of the business in the ancient business world and the family.
