From Han Yangling to Xian Airport

Hello, I would like to visit the mausoleum before taking a flight. Do you know if I can easily find a taxi at the mausoleum to drive me to the airport after my visit?
I will arrive to this place with public bus, but then I know that there is no bus from this place to the airport. That is why I am thinking about a taxi.
Thank you for your answer!
