I will be arriving in Shanghai Pudong at 6.30 am Jan 20,2013,then to Zaozhuang.

Hi, you can take subway line 2 from the airport to Hongqiao Railway Station, where you can catch the high-speed train to Zaozhuang in about 3h.

Your arrival time will be during the Rush Hours, so the subway may be very crowded. In that case, you can also directly take Airport Shuttle Bus line 1 to Hongqiao Airport, from where you can walk around 10min to Hongqiao Railway Station to take the train to Zaozhuang.
