Xi'an Airport to Hantang House (near Xincheng Square)

1. You can choose either Main Railway Station Line or East Street Line. By either of them, you can get off at the terminal station. Then your hotel is within 2.5km away. Take a taxi to reach with the cost of CNY9-10.
2. I suggest you take a taxi to local Main Railway Station with CNY9. At the east square of the rail station, take tourist bus line 5 (no. 306), 914 or 915 to the museum directly.
