Long 13 hours layover on Chongqing, can I leave the airport for a couple hours?

Hello I`m traveling from New York (JFK) transit in Chongqing (CKG) (13 hours layover) final destination Beijing (PEK), I`m from Ecuador traveling with a regular passport, we don’t need visa to visit China, my question is if I can leave the airport to visit the city in Chongqing and then come back to take my flight to Beijing, and if possible what is the procedure to do so?
