Airport change in Shangai, French passeport

I am a French passport holder living in Tokyo and travelling with my son to France via Shangai this summer. we have an airport change (i.e. Tokyo to Shangai Hongqiao and then Shangai Pu Dong to Paris) with 7 hours to go from one airport to the other in Shangai. Do I need a visa for the 7 hours between the 2 airports in China?
