How to get from Guilin Airport to Yangshuo after 20h00

Hello,

We will be landing from Shanghai at 20h15 and I am wndering if there is a way to get to YS with public transportation still at this time.
Some website show the last bus leaves at 22h30 but you mention that the last one is at 20h00. Does the coach company has a www page to double check the schedules?
Thank you
