Few hours in Quanzhou, can we take a short visit?

Hi! We have a few hours to spend in Quanzhou before moving to Shanghai. We arrive in Quanzhou Airport on Oct 11 at around 12:30pm. We plan to book a flight to Shanghai the same day at around 11pm. What are the best places to visit given our limited time? Also, what is the quickest way to get in and out of the JJN airport? How bad is the traffic and how much time should we allot for travel?
