free cross-terminal shuttle bus between T2 and T3 of Xian Xianyang Airport.

we will be arriving at the airport at 11.15pm at T2 and we need to go over to T3 for our next flight. Above information says the free cross-terminal shuttle bus runs from 8.30am to 8.00pm.
May I know how much does a taxi cost to T3. Thank you
