Qiao Qinghe - the daughter of a wealthy businessman from Yuhang, the real "head of the Qiao family" behind the scenes
Appearance: A sickly legitimate daughter, gentle and harmless, who "recuperates" in her boudoir all year round
Reality: The actual operator of the Qiao family's business empire, while her two brothers charged outside, she was behind the scenes. Under the upbringing of Song Ruoyan (aunt/concubine) since childhood, she learned the Song family's way of life of "conquering strength with softness", and also learned the "taking advantage of the situation" mentality taught by her biological mother Song Xinyu before her death.
Core trait: Extreme sobriety. She never believed in love, only "value exchange" and "interest bundling". She chose Zhennanhou not because she was desperate, but because it was the best solution.
