how much distance between Guangzhou airport and Metros line 3?

Oh, I remember that the distance is about 220 yards. There are detailed English signs in the airport. You can find the metro station easily. :-)

Hi, Mir Wali. Actually, the subway station is just located inside the airport, linked through to the arrival lobby. When you get to the arrival hall, there are clear signs in English showing the direction to take the metro. The esclators and special passage will lead you to the subway station level easily.
