Can I stay in chaoshan airport overnight?

Hi, I have a long layover (from Feb 9 16:25 to Deb 10 08:25) at Shantou airport and I'm wondering if I can stay in the airport that night. I know it would be more convenient to stay at a hotel but I do not want to travel far from the airport and I want to save some money. Is there a hotel at the airport? Can I wait overnight in the airport terminal? What do you suggest I do?

Thank you! :)
