The story begins on the winter night of 2023, when 78-year-old Lin Guifang froze to death in a bridge hole. Before she died, she heard the voices of her children in the family: "The old lady is finally dead, let's keep the funeral simple." What made her vomit blood even more was that her husband Zhang Jianguo's Bai Yueguang and Liu Meilan came with their illegitimate children and taunted her: "Sister, you have raised my children for me, it's time to give up."
