Information PEK - PVG

Hello,

I booked the flight with e-ticket 9991602355088-089, I've got an Italian Passport.

As you can check, my return flight will be on 25th of August with the following flights:

1) TOKYO HND - BEJING PEK
2) BEJING PEK - SHANGHAI PVG
3) SHANGHAI PVG - MILAN MXP

I'll make two stopovers in China, but I don't intent to leave the airports and the stops will be very short also (less than 24h).

Do I need a visa for BEJING PEK - SHANGHAI PVG?

Thank you for the quick answer.
Have a nice day,
