Zhou Ying is sold to the powerful Shen family by her foster father, yet successfully escapes her childish master Shen Xingyi by sneaking into merchant Wu Pin’s palanquin. The Wu family agreed to take her in after witnessing her remarkable business acumen, and she ends up marrying Wu Pin. After Wu Pin's untimely death, Zhou Ying takes it upon herself to keep the family business afloat and take care of the Wu household.
On the other hand, Shen Xingyi has also decided to turn over a new leaf, and is now Zhou Ying's biggest competitor. Shen Xingyi's love for the heroine is initially unrequited, though Zhou Ying eventually acknowledges that she has developed romantic feelings for him. However, they both realise their personal affections are of little importance in the face of political upheaval, and Shen Xingyi joins the reformists advocating modernization of the Qing Dynasty after returning from an overseas education.
