Recently, Nanjing's bus line 503 has embraced a dual role with the innovative integration of a 'Little Blue Whale SF Half-Day Delivery Warehouse' at the rear of the vehicle. Commencing each day at 15:30, this bus embarks from Liuhe North Station, not only carrying passengers but also transporting agricultural products, fresh food, and other express deliveries to the heart of Nanjing. Serving as a vital link between Liuhe District and the city's core, bus line 503 traverses a daily route from Liuhe North Station to Drum Tower Bus Terminal, stopping at over 60 stations along the way.
