Don't trust at all for the direction information. Because the line 2 yet still on progress without any notice but already show on in the ticketing where if you go to buy the ticket and you will never get it untill you asking the other.
The subway route is limited, but it gets you to most of the good areas. It is excellent if you want to get across town quickly. Running from the East Train Station to the Fancun Bus Station, it is very convenient if you need to get a bus in Guangdong or a train out.
metro or subway in Gz has 5 lines, very convenience and cheap to go around.
Pic is only to show the atmosphere of the metro station
This city is served by two modern and efficient underground lines.
Line 1 - Guangzhoudongzhan - Xilang
Line 2 - Sanyuanli - Pazhou
