You have to take a bus from Taicang to Kunshan Bus Station, and then transfer to Zhouzhuang Bus Station. When you arrive at Zhouzhuang, after leaving the station, there is a Zhouzhuang Hotel diagonally opposite the station (a little farther, at a T-junction). Wait at the gate of that Zhouzhuang Hotel for 888, which is a town bus and can go directly to the School of Applied Technology of Soochow University.
