“Psychological Emptiness” typically refers to a subjective experience characterized by inner emptiness, a sense of meaninglessness, emotional detachment, and skepticism or denial toward the value of one’s existence and the surrounding world. It is often associated with psychological traits such as a lack of core values, difficulties in selfidentity, diminished life purpose, and mental fatigue. In recent years, a growing number of young military personnel in grassroots units have exhibited similar symptoms. Due to the unique demands of military environments and missions, cases of “psychological emptiness” among young service members demonstrate distinct features shaped by military contexts. The development of this phenomenon is influenced not only by individual factors—including cognitive development, personality traits, and mental health status—but also by external factors such as family upbringing, educational experiences, and military management practices. Moreover, it reflects deeper societal roots and zeitgeistdriven characteristics. This paper examines a case study of a new recruit, Xiaolin, to analyze the unique manifestations of “psychological emptiness” among young military personnel and proposes strategies for intervention and prevention.
