if i take train from the beijing to harbin..which station i will be arriving?

This depends on the ride you choose. All the high speed rides stop at west station. Most normal rides stop at Harbin railway station, a few use west station.

ooi see..i will ride on the first class seat..so it wil arrive at west station right? about the transportation..what will the taxi fare from the station to ibis hotel? and how long it will take? any bus from the station to hotel? tq

If you take first class, you will arrive at West station. You will stay in ibis Harbin Shangzhi, right? Which is located in No. 92 Zhaolin Street near Near Saint Sophia Church? If yes, the taxi fee is about 30RMB, and will take about half an hour. You can also take bus No. 64 at east square of the West station, which will take you about 70 mins. Hope it helps.

thank you so much! another one..how i can i go to dao wei? taxi?bus or train?

Do you refers to Daowai Distric? The distric covers an area but buses and taxis can be used for transfer.
