The quickest way is to take the subway, which takes about one hour.
Take the subway from Baiyun Airport, take three stops, and arrive at Jiahe Wanggang Station-note that it&;s only three stops, so don&;t miss it.
Transfer to Line 2 (this is the starting station, so you don&;t have to worry about taking the wrong direction), take 17 stops, and you will arrive at Dong Xiao South Subway Station.
