Can I apply for the free transit visa and which visa to apply for thai passport holder?

I am holding a thai passport travelling from Singapore (SIN) to Shanghai (PVG) with a stopover time of 10hr before the next departure from Shanghai (SHA) to Seoul (GMP). I have to travel between the airports. Can I apply for the free transit and which to apply? I will reach Shanghai at 10:05pm and depart 8:20am the next day? If I am able to go out to the city, is there any activities such as acrobatic shows/shopping or sight-seeing tour that you can recommend for this period of time?
