Hi, I'm planning to travel from Xi'an to Qianling Mausoleum for a day trip.

Understand that Tourist Line 3 is no longer in operation. I found that I'm supposed to go to Chengxi Passenger Transport Terminal 西安城西客运站 and take a bus to Qian County 乾县. I found some mix answers on the bus timings and is very confuse (one indicated once every hour, while another only states there's only one bus at 3pm per day). Anyone knows actual the frequency of the bus timings?

Also from Qian County 乾县, I'm supposed to take a Local Bus 2 to Qianling Mausoleum? Where can I find Local Bus 2?
