I don&;t suggest that you take a bus to Qingyuan and then transfer to Fogang, because it takes an hour for Baiyun Airport to go to Qingyuan and more than an hour for Qingyuan to go to Fogang. I suggest that you take a bus or take a taxi directly to Huadu Bus Station after getting off the plane (Guangzhou Baiyun Airport is in Huadu District, not near Guangzhou), and there is a direct bus from Huadu Bus Station to Fogang, which is about an hour.
