I need to go to Zhenjiang, Jiangsu University from Pudong Airport. Please help. Thanks.

No direct public transportation is available for this route You are suggested to take airport shuttle bus line 5 to SH Railway Station. There you can take a bullet train to Zhenjiang. After arriving, you can take bus no. 19 to Rushan Station. Then walk to the university directly. Or you can just take a taxi to the campus. The taxi fare is about CNY 25.

Thanks so much.....Question.....Why SH Railway Station? Why not Hongqiao Railway Station?? whats the pro and cons??
Btw, I am carry 2 baggage weight 27kg...

Actually, both railway stations can be ok, but the SH station is much closer to PVG.

It's ok for you to take a train to Hongqiao Railway Station.
You can take direct airport shuttle bus line 1 to the Hongqiao Train Station.

How about take line 2 direct to Hongqiao?

Subway line 2 from PVG to Hongqiao takes 90-100min.
