i am reaching Pudong airport on 30th Evening 4.30 I need to go to Huaian city by Fast train or Bus

Take airport shuttle bus line 5 to local main Railway Station, from which you can walk to the General Bus Station. There you can easily take a direct bus to Huaian.

Ticket of shuttle bus can be bought onboard and the bus ticket for Huaian needs to be bought at the bus station.
