Transfer from Xian airport to Angsana Lintong

Hi! My name is Clara and I will be arriving in the airport from Shanghai on Sat 27 Aug around 1 pm. I need to go to Angsana Lintong to meet with some friends. Which is the cheapest way to get there? I am not in a hurry but checking on the Google map it might take up to 7 hours... with public transportation. Many thanks for your reply, Clara
