I would like help booking my train ticket before i arrive in China.

I am trying to book a train from Beijing to Yantai, specifically the 2915 train departing at 19:00, but your form requires that i have a Chinese hotel address for ticket delivery. This would be impossible for me because I want to book my train before i arrive in China. I leave September 3rd for China and arrive September 4th at 16:00 and i want to take the train right after I am done with immigration. That is 7 days from now so if you could respond to me as soon as possible so i can meet your 6 day prior to departure requirement. Thank you for any help.
