Hello to Travelchinaguide Team!

I have a return ticket from Vienna to Shanghai (via Paris)
FLY THERE: 8.5.
FLY BACK: 14.5.
and a return ticket from Shanghai to Tokyo in the middle
FLY THERE: 12.5.
FLY BACK: 13.5.

Could I possibly obtain the 72h transit visa (or 144h)? Am I considered as a transiting traveler?

Your answer will be much appreciated.
