Su Wanhe meticulously cared for her seriously ill adoptive mother Li Dongmei for ten years. After the elderly woman passed away, her biological children Su Wanping and Su Qingfang not only failed to fulfill their filial duties, but also grew jealous of the tens of millions in assets left by the elderly woman, such as the mutual aid association. They forged a will, caused trouble at the door, and spread rumors online, slandering Wanhe for defrauding the inheritance. Faced with the extortion, harassment, and public opinion attacks from the two siblings, Su Wanhe produced the elderly woman's hospital admission records, handwritten account books, and true will, exposing their lies one by one. She successfully was elected as the president of the mutual aid association, safeguarding the elderly woman's hard work, yet she always remained puzzled about the reason behind her aunt's coldness and bias toward her during the last ten years.
