Ask for bus line in Guangzhou

You can take the airport shuttle bus line 5 to reach Haizhu Plaza and then take a taxi to reach your apartment.
Or you can take the local subway line 3 to reach Jiahewanggang station and then change to line 2 to reach Haizhu Plaza Station and then take a taxi to reach your hotel.
It is highly recommended to take the shuttle bus, because it is fast and more comfortable than the subway.
