Hi, what is the best way to travel between Shenzhen Bao An Airport to Guanzhou Baiyun Airport.

First, you may choose to take a a long distance bus from Baoan Airport to Guangyuan Bus Station in Guangzhou and then take a taxi to Baiyun Airport.
Second, you may choose taxi or airport shuttle bus to Shenzhen Railway Station first and then take a high speed ride to GZ East Station and then take subway line 3 to reach Baiyun Airport.
