This essay treats "Fu 10" as a locus for these tensions: a code name for a place, a machine, or a phase of life where nocturnal wandering and deliberate repair intersect. Imagine Fu 10 as an old transit yard on the outskirts of a sprawling metropolis—once a hub for the early-morning freight trains, now half-retired, its tracks pocked with weeds and its signal boxes coated in graffiti. At night, Fu 10 is both refuge and crucible. It draws insomniacs, laborers finishing late shifts, lovers seeking privacy, and the occasional artist chasing the glow of sodium lamps. Each arrival carries a distinct history, yet the night equalizes certain elements: the clarity of starlight, the hum of refrigeration units, the distant throb of highway traffic.
