Hi,
I am landing after midnight at the Guangzhou Airport and I want to go to Hongkong.
I heard that the fastest and cheapest way is to take train to shenzhen and then from there the subway to Hongkong. Could anybody confirm this? Or advise me an other way?

Because I arrive this late, I guess that there is no train or bus driving, even to Guangzhou city, doesn't it?

Thank you very much
