Accommodation for the layover of 15hrs 50mins at Guangzhou airport

According to my Qatar airways flight itinerary. I will arrive at Guangzhou airport at 15:30, Sep 11 and have to wait till 7:20 the following day (i.e 15hrs 50mins layover) for Shenzhen airlines to take me to Changzhou my final destination. Will i find a good place to lay my head at the airport there while i wait for my connecting flight pls?
