hello, i want to go from baiyan airprort to pazhou exibition centere, from where i can get train and ticket?

Hi, according to the guiding signs at the airport, walk to Airport South MTR Station to take subway line 3 to Kecun Station first. Then transfer to subway line 8 to Pazhou Station. Upon your getting off, you can easily walk to your destination. You can get the subway tickets at the corresponding MTR stations.
