From where does the bus leave Wudangshan and at what times to go to Xian on Friday July 6th please?

We would also like to know where the bus from Wudangshan will stop in Xian because we are being picked up there by our private tour guide. So what is the name of the bus terminal in Xian where we will get off please?

Thank you very much for your help
