Transit

Hi, i have a plan to return to Indonesi
My itinerary: (Russia - China - Indonesia)
Vladivostok - Dalian (transit in Dalian 7 hours 20 minutes)
Dalian - Shanghai (transit in Shanghai 19 hours 10 minutes)
Shanghai - Jakarta
I will not exit the airport in Dalian during the transit, but I plan to explore Shanghai during my transit. Could I transit in China with that itinerary without visa?.
Thank you
