Bus Service to Guangzhou Airport from Shenzhen?

Now Shenzhen   |   August 27, 2021

Can anyone tell me if there is a bus service in Shenzhen which can tkae me to the Guangzhou Airport directly? I know the train system which will take me to the Guanzhou train station but then I will have to taxi to the airport. But I prefer to take the direct bus to the airport if available. Thanks
