Shen Qingci, the legitimate daughter of a wealthy merchant in the south of the Yangtze River, married into the run-down Xuanping residence with a generous dowry to make up for the shortfall and take care of the family. Unexpectedly, after the Lu family gained a foothold, they married Liu Waner as their concubine in order to cling to the powerful, and forced her to give up her seat to serve tea at the wedding banquet. Shen Qingci, who couldn't bear it anymore, slapped her in the face with her backhand, flipped the table to fight back, angrily withdrew all the dowry, and cut off the Lu family's source of income. Faced with the Lu family's greedy calculations and poisonous schemes, she was cautious at every step.
