Is there a direct airport bus at Urumqi South Station? Where can I take it?

Yes, but not always. The first stop of the bus route to the airport is the South Railway Station, just in front of the self-service ticket vending machine in Little Square, where there are buses and Jinbei. If you happen to see a car when you go there, you can get on the bus and wait. This shows that you are lucky. If you find that there is no car (that is, it will be between two cars), then time allows you to wait for a while. If time is short, try to take a taxi. Remember to agree on a price of around 35. Although the management office has repeatedly stated that taxis are not allowed to wait for passengers there, there are also some black taxi drivers. So it depends. Oh, I tell you, the bus seems to be 10 yuan alone. I've been there several times, but twice I just didn't wait for the bus to carpool.
