The 72hrs free visa has restricted airports in Shangai?

Good day,
In the 144hrs free visa says: " Shanghai: All air, sea and railway ports, including Pudong Airport, Hongqiao Airport, Shanghai Port International Cruise Terminal, Wusong Passenger Transport Center and all railway stations."
Im planing an arrival at Pudong airport, but just staying at Shanghai for less than 72 hrs. Does the 72 hours free transit aloud me to arrive & depart from Pudong airport or just the 144hrs free transit let me use that specific airport that I need?
