How to get to Ibis Xian Heping by bus or taxi. How much for taxi after 22:00 hrs.

Either can be ok.

By taxi, it costs CNY120 at that time.

By bus, you can take shuttle bus line 2 to local railway station. Then transfer to take a taxin to your hotel with the taxi fare of CNY10. As I know, the last bus of line 2 leaves the airport at 22:30. Hurry up and you may catch that.
