Li Yingjun, the owner of a high-end residential complex, held his son's wedding. After the owners forced his neighbors to pay 8,888 yuan in gifts, provide vehicles to pick up the bride, and choose bridesmaids, but "I" refused, they teamed up with family members and relatives to continue harassing and retaliating, including smashing doors, making noise, puncturing tires, spreading rumors and slandering, and other evil deeds. "I" could not bear to be disturbed, so I joined forces with my neighbors who were also oppressed, and enlisted the help of my cousin Gu Ze, who had mania. I treated him the same way as he did, and used cockroaches, thumbtacks, etc. To fight back. Finally, his evil deeds were exposed at the wedding scene. With sufficient evidence, Li Yingjun was taken to court, and he was sentenced to three years in prison, successfully driving the family out of the community.
