1) I missed out to check one thing. I'm heading to LiuHua Hotel Guangzhou straight after reaching Shenzhen Airport. I'm checking the train schedule from Shenzhen Railway station to Guangzhou Railway Station. Since I'm staying in LiuHua hotel, which destination in ur website that i should click the "From" and "To" (Because i saw many options of Shenzhen and Guangzhou). Which one should I select, from "Shenzhen" or "Shenzhen West"? To "Guangzhou" or "Guangzhou North"?

2) Can the bullet train ticket be purchased online? Or it has to be purchased in Shenzhen Railway Station? Does Airport sell train ticket please?

Thanks.
