what is the procedure to get this lounge at Beijing Capital Airport?

I will travel from DXB to MNL on 23 Dec 2010 and MNL-DXB on 15 Jan 2010, both trips will have a 9-10hours stop over on Beijing Capital Airport on the next date of the respective dates that I mentioned. I saw here that there is a hourly lounge inside the airport, if may I ask, what is the procedure to get this lounge? do i need to pay per hour or is this free? Kindly tell me the details. Thank you.
