Do I need a entry visa?

I have a nationality of Finland and I'm planning to be 34 hours in Shangai PVG. My route is BKK - PVG - HEL. (Every flight in the same ticket). Do I need to get an entry visa?? Beforehand, at the airport or do I need to do that at all? Timatic says that nationality of Finland can transit 144 hours.

Just to be cleared it says: "Visa required except for nationals of Finland with a confirmed air ticket to a third country within 144 hours, starting from 00:01 on the day following the day of entry. This facility applies in the following location: PVG Pudong airport." Who says that it's 72 hours?

Is this true? And can you specify what is a Departure / Arrival Card?

Thank you
