Philippine Passport holder travelling DXB-CJU with 21:55 hr long-wait connection from Shanghai

Hello! I am travelling to Jeju Island from Dubai with a stopover of 21:55 hours in Shanghai. Will I need to apply for a transit visa if I want to go out of the airport and have a sight-seeing while waiting for my connection? My return flight to Dubai has another stopover of 16:10 hours again in Shanghai.. please let me know.

Thank you very much.
