I am supposed to arrive in Tianhe International Terminal in 7:10PM(airplane arrival time)

In this early September, and I want to catch the long-distance bus to Xiangyang City, I know the last one is 7:50PM.

Is that bus station far away? How long by walk?
There would be only 40 minutes for me to checkout the customs and pick up my luggage, walk to the bus station and catch the bus.... do you think it possible? It's my best choice, otherwise I have to go to Hankou Railway Station.

Thank you!
