In the seventh year of the Republic of China, Shanghai was in the French Concession. When Shen Huaijin, the third concubine of the Nie family, was given hairpins, the eldest wife Lin Peizhen deducted her monthly report for half a year in public, saying that her "life is too precious and needs to be suppressed." The concubines in the hall laughed at him, and his aunts rejoiced in his misfortune. Shen Huaijin knelt down and took the halved red envelope, but the corners of her mouth were slightly raised - last night she had "accidentally met" the president of the French Concession Chamber of Commerce with her auspicious destiny, and won a shipping order for the Nie family that could not even negotiate a big house. The next day, the old man of the Nie family personally asked about the matter, and the eldest lady's face was ashen. Shen Huaijin took the opportunity to propose taking over the accounts of Sanfang, on the grounds that "my daughter is destined to be rich and will bring good fortune to Sanfang." The eldest wife was riding a tiger and couldn't get off, so she had no choice but to agree. No one knows that this is just Shen Huaijin's first step. She used her "auspicious" persona to deal with each house: helping the second house avoid a strike crisis, helping the fourth house solve the supply shortage of textile raw materials, and even asked Aunt Su, who had been suppressing her, to take the initiative to ask her for help. Every time she helped, she quietly gained a piece of power - warehouse keys, shop ledgers, and concession network. When the eldest wife finally realized that something was wrong, all the shopkeepers and clerks in the third room only listened to Shen Huaijin's orders, and half of the ship owners at the shipping dock recognized her as a direct descendant of the Nie family. The eldest wife teamed up with the fourth aunt to organize a Hongmen Banquet, but Shen Huaijin produced ironclad evidence of Nie Zhenbang's private sale of family property in front of the whole family and turned the army against him. "What's the difference between direct concubines and concubines?" Shen Huaijin picked up the tea cup and smiled calmly, "The family law of our ancestors only says that those who are capable should take over. Madam, it's time to hand over the little power you have."
