Route number is 4. Remember it—the number stays the same everywhere: on the stop display, in apps, on the vehicle itself. Look for 4 specifically. If you're not sure you found the right stop, just ask someone nearby: 'Does bus 4 stop here?'

This route serves the Nanjing (China) region. In larger metro areas, routes can pass through several districts or towns. To know for sure if it works for you, pull up the route map and check the key stops and direction.

Starting point is 新街口西站. Usually at the first stop there's a turnaround or layover space where drivers rest between runs. If you want to guarantee a seat, get on here—the vehicle is just starting out and still mostly empty.

Final stop is 银城东苑. Everyone gets off here, the vehicle turns around and heads back after a few minutes. Missed your stop? No big deal—just ride to the end and come back on the same route.
