I want to visit Xi'an Jiao Tong Uni at Suzhou from Pudong airport (07 am), how to proceed?

First of all, take long-distance bus from PVG to Suzhou Bus Station (North Square of Suzhou Railway Station). The earliest schedule is at 09:20. It takes around 3 hours on the way with the ticket fare is CNY84 per person. Then take bus No. Kuai2 to Nanda Yanjiushengyuan. After arriving, walk southeast around 350 meters to find the university.

There is no airport in Suzhou. Thus you need to back to SH first. Pudong and Hongqiao Airport both are ok.
