Do I need transit visa? I hold a Paraguayan Passport.

I hold a Paraguayan Passport an I have Japanese resident visa as well.. I am traveling from Tokyo-Paris-Tokyo ( its a round trip) and I will stay for 5 hours at Pu dong airport in Shanghai on my way to Paris and 2 hours when I comeback to Tokyo using China Eastern Airlines .. So I want to know if I need a transit visa for that trip.
