Panamanian with student residency in South Korea

Hi this is a follow up to the question above by Lill. We would like to leave the airport and see a bit of China during a long layover. The layover is just a bit over 24 hrs. Can a Panamanian with a South Korean student visa get a free transit to visit china outside of the airport. Or can only change plans in PRC and must stay in the airport. Thanks for the clarification.
