I would like to have informations about Guilin-Yangshuo bamboo raft

Hi there guys, I would like to have informations about how to get to the dock where taking the bamboo raft from Guilin to Xingping village on the Li River?
I am at present in Guilin city, but I don't know how to get to the dock where taking small bamboo rafts (not big tourists one). I know that is around 1 hour drive from Guilin. Should i go in the train station first and ask for that? which number or name of bus, stop, etc... thanks a lot!
We'll be 2 persons and we prefere travelling this way! ;)
