At Guangzhou Baiyun airport, can you get a train (bullet or high speed train) to Dongguan station?

Hi there

1) I wanted to know whether it was possible a direct train from baiyun airport to Dongguan station or would I need to go to GZ east railway before getting a fast train to Dongguan?

2) Is it possible to get a transportation smart card from the baiyun airport? Can I top this up and use it on high speed trains?

Many Thanks
