Back from City to Harbin Airport by bus

Hey, can you tell me where are you exactly? Or I cannot tell you how to go.
BTW, you can buy the bus ticket in the place where you boarding the bus.

Hello Frank. Thanx for your answer. But I´m still back in Beijing. The Bus stop to the Airport was excatly opposite the last busstop, where i left the bus at Jingweig Street, not far away from Shangzhi Street. It was line 3 I took from the Airport and back.
I bought the ticket in the Bus during the last stop into the direction to the Airport. A woman came in and collected the money..
To find a Airport Bus Stop for foreigners like me isn´t not so easy, when you cann´t read chinese. At the blue sign is a small Airplane in the left corner.
