I will reach Shanghai pudong at 20:30,can u suggest some hotel, next mrng i have to go to nanjing by train

I suggest you find a hotel at the city center area(Nanjing road, People's Square area) so that it is easy for you to take subway to the railway station the next morning. Motel 168 of An Yuan Road, Shanghai at No. 678 An Yuan Road, Jing An District,Shanghai may be PK.
