Should I need to own the paper ticket when I get a free-transit?

I will go to HongKong via Beijing. So I get a ticket. I have now received a ticket to Beijing and issued a ticket to Hong Kong.
But I couldn't get a real ticket to Hong Kong in my hand. The ticket was delivered to the hotel in Beijing.
So, I can only prove by copied paper that I have the ticket.

In this situation, can I enter without china visa? or should I get a original ticket to enter the China?
