Hi. Can you give me the daily bus schedule from Guangzhou to Yangshuo? Thank you

As I know, there are many buses in different bus stations from Guangzhou to YS.
For instance, from Guangdong Provincial Bus Station, the buses are at 08:30, 09:45, 11:30, 13:00, 18:30, 20:30, 22:00 and 22:50.
From Tianhe Bus Station, the direct buses exist, too, but for the detail information, I am not very clear.
