The line is identified as 4. You can find this designation on metro maps, signs in passageways, platform information boards, and transport apps.

This metro line runs through Shanghai (China). Metro lines typically connect several parts of the city — from residential neighbourhoods to business districts and the city centre. To find out whether this line suits your journey, open the metro map and check the station locations relative to your destination. Sometimes one transfer is more convenient than searching for a direct route.

The first station is 宜山路. At terminal stations, trains typically wait a few minutes before departing in the opposite direction, so this is a convenient place to board — you have time to find a seat without rushing. If you are travelling during peak hours and want to avoid the crowds, boarding at the terminal is one of the best strategies.

The last station is 宜山路. All passengers must exit here, after which the train departs in the opposite direction. If you accidentally miss your stop, don't worry — simply ride to the terminal and return in the right direction. This takes a little extra time but does not require an additional fare.

On metro maps, this line is shown in #5F259F. Colour coding is the primary navigation aid in metro systems — it helps you quickly identify the right direction on signs, maps, and information boards.
