Since those are the numbers from the website, it makes sense. Personally, I would just go to an agency in person. Flying in China is very, very different than in the US. Ticket issuance is pretty laid back.
E-long had an odd procedure last year - I put in that I would pay on their website with a CC, they called me, told me "pay cash, it's cheaper." I replied that I didn't have that much cash on me at the moment (something like 5500 RMB or USD, which since the largest unit of currency is 100 RMB, would be 550 bills... ). So they sent me an email with a form for me to fill out and fax back to their office.
Then, they sent me an email and said everything was OK.
A couple hours later, a man speaking in heavy Beijinghua dropped off my ticket from his motorcycle.
I was a bit confused by the process, but my credit card was safe, my tickets worked ok, etc., etc.
Would I do it again? No... I'd just deal with someone face-to-face. Far easier!
