The novel uses the fatalistic daily image of "a thermometer dropped into the refrigerator - plummeting" as the core metaphor, depicting the survival picture of a middle-aged man Xiang Ming who suddenly plummeted from the peak to the freezing point after experiencing marital betrayal. The uncontrollable fall of the thermometer not only symbolizes the breakdown of the marriage relationship, but also heralds an extreme test about self-awareness, emotional resilience and life reconstruction.
