We had a free pass to the airport lounge in Guangzhou from a promotion linked to our credit card. In total our Paris stopover was 6 hours and we were allowed to spend 3 hours in the Guangzhou premium lounge.
In the lounge you will have access to a hot shower with towels, hot food and drinks, deserts, a snack bar, WIFI, a recliner area for sleeping, many power outlets to charge devises and a common lounge area when you will probably spend most of your time.
After 3 hours exactly we had the hosts at the lounge come and tell us that our time is up. I am not sure how they knew it was us that had to leave but they were very anal about the schedule.
It was a nice lounge with good service and everything you need in one place. If traveling through that way again I will definitely use them again.
