The mother of his daughter-in-law said she would only stay three days, yet she brought her whole family, took over the master bedroom, moved their household registration, and stole the property deed. Worse still, she joined forces with Gu Mingzhu's son to drive Gu Mingzhu out of the house. Everyone thought she was just a poor fish-selling mother-in-law.
