This book tells the story of how three good people pushed each other into an abyss of eternal destruction in the way they thought was right. Li Gang, Wei Xiaomei, and Fang Xue, they are all kind, sincere, and believe that they are doing the right thing - because of this, this tragedy is irreversible. If there were bad guys in it, the story would be easier to handle, but the most cruel thing about that era was precisely that: the system did not leave a way for "good guys" to survive, and everyone's good intentions became part of the noose. Li Gang's retreat is kind, because he is afraid of dragging Wei Xiaomei down; Wei Xiaomei's persistence is kind, she thinks love can overcome everything; Fang Xue's watchfulness is kind, she thinks companionship can bring about sincerity. Three kinds of good thoughts entwined with each other, twisting into a rope that got tighter and tighter, and finally hung the three people's lives.
