Please help on how to get to Huangpu District from Pudong T2.

Hi, Huangpu District covers a large area, so I can just give you a general direction.
The central place - Nanjing Road, is at this district. So you can walk from T2 to the Aiport MTR Station to take subway line 2 to East or West Nanjng Road. Then you can easily catch a bus to your certain destination.
