Where do i go down at shanghai city proper

Hi,

My flight is arriving at 23:45 at Pudong International Airport, i assumed i will step out at Pudong at around 12:30 midnight. How do i go to Shanghai City proper by bus? I'm saving money and does not want to take a taxi. Are there schedules on midnight and where do i go down if my hotel is in wusong road near the bund (Hengsheng Peninsula International Hotel). Please help.

Thanks you,

Jordan
