How can I take metro, bus... from Xianyang International Airport to Holiday Inn Xian Greenland

I'm afraid the MTR is not available. I suggest you take shuttle bus line 3 to Gaoxin (Hi-Tech Development Zone), which is around 5km from your hotel then. Upon your getting off there, you can take a taxi to reach the hotel exactly or walk to Gaoxin Road Station to take bus Gaoxin Line 1 to Jinye Road. After that, you can easily walk to your hotel.

The shuttle bus costs you CNY26 and the bus fare is CNY1. If you plan to take a taxi from Gaoxin to your hotel, the taxi fare is around CNY15.
