I want to get to Ganzhou from Guangzhou. I land into Guangzhou airport at 18:20 and miss the last train I think. I have heard that there are buses from Guangzhou to Ganzhou every hour until 9pm. Can somebody please confirm this is true? and which bus station this bus departs from in Guangzhou? Other info on how long it takes and how much it costs would be very helpful as well. How can I get from Guangzhou airport to this bus station?

Many thanks for anyone who can help:)
