Are you sure this reply is really correct?
On this exact same page your information is:
Collect at airports. Foreign visitors usually arrive in China at the international airports in Beijing, Shanghai, and Guangzhou. Some airports have railway ticket offices inside the terminal buildings, and the staff there usually speaks English. A service fee of CNY5 per ticket is charged. This is available at the following airports:
• Shanghai Pudong Airport: B06 Room, Maglev Station; the connection area between Terminal 1 and Terminal 2. Office hour: 08:00 - 18:00.
This seems to suggest you can book the tickets on TCG, then collect the paper tickets at the bigger airports (as longs as you pay the extra fee there of CNY 5 per ticket).
I plan to do the same at Guangzhou airport based on above information. If this information is not correct, could you update it on the site? Thanks!
