Hi! I am planning to go Hong kong from Guangzhou by train.
- Is it possible to book the tickets online?
- Do I need to buy the train ticket 6 hrs before departure? I read it from somewhere else!!
- How many hours before should I be there in the Guangzhou East Station?
- Is there a direct bus where I can get to the Guangzhou East Station from Baiyun Airport?
- Is there any other ways to go Hong kong from Baiyun Airport?

Thanks a lot!
