How can I proceed REQUIRED TICKET COLLECTION in Booking Form??

I will take international train from Beijing to Ulan Bator in mid-May, 2015.
When I complete booking form, this required step below blocks my procedures.
I'm a Japanese traveler, so I don't have any address in China.

Could you tell me how to proceed this step?
