Narrated from the perspective of Chen Zhixia, a writer documenting the intercity migration history of the Yangtze River Delta, this story unfolds through a vintage 1987 “Shanghai-Suzhou” train ticket, unveiling the poignant emotional legacy of her grandparents within a specific historical era. Utilizing a “time-traveling” narrative technique, the novella reconstructs the literary contrast between the cramped, bustling “green-train” platforms of 1987 and the modern, standardized Suzhou Industrial Park Station. It explores how “non-places” within industrial civilization serve as repositories for personal memory and nostalgia. Centered on the “magnolia flower” as its core imagery, the work symbolizes the grandparents’ unwavering and sincere devotion amidst life’s trials and historical upheavals. Through her quest for family secrets, the protagonist undergoes a psychological transformation in her perception of twin-city spaces, from “sterile transit hubs” to “emotional vessels,” profoundly reflecting the hardships and tenderness of intercity migrants during China’s urbanization process.
