Predawn Logistics Envelope at Xian Sorting Belt

Amber firelight warms the metallic surfaces of an industrial sorting belt in a Xian warehouse during predawn darkness. A weathered paper envelope labeled with route mileage sits centered on the moving conveyor, its rough texture catching the low glow. Beyond the envelope, the facility hums with organized hardware separating intermodal bookings from freight accounting tasks. Cold window light slices across the floor, creating sharp contrasts against the warm machinery tones. Leading lines of the conveyor system draw the eye deep into the facility where automation maintenance stations stand ready. The envelope's edges are frayed, showing signs of heavy use before the daily rush begins.
