Shen Zhiqiu watched helplessly as her husband Cheng Yanzhi took the blame for his brother-in-law and was imprisoned, just so that he could go to a key high school. She endured it for three years, until she discovered that her mother-in-law, Cheng Wu, had used a tampered genealogy to erase her husband's identity as a direct lineage, and she completely collapsed. She smashed the shrine in the ancestral hall, burned the family tree in public, and revealed the hypocrisy and orthodoxy that three generations of people had paid for with blood. The silent return of the husband, the tears of the furnace keeper, the hypocrisy of the brother-in-law, and the quiet appearance of the new member of the Discipline Inspection Commission, all make this revenge more than just a family fight - it is the strangulation of human nature by the old patriarchal system, and the starting point for a woman to be reborn from the ashes.
