My brother and one of my friends come to visit me here (Beijing)

and we want to travel to Shanghai and Hong Kong by rail. My brother and one of my friends come to visit me here (Beijing) and we want to travel to Shanghai and Hong Kong by rail. The thing is I don't have their passports and I need it to buy them in a ticket office. So can I book it on your website? I'm not interested in the deliver service; just take it from the railway station or in your agency in China. Thank you in advance.
