Can I take a bamboo raft from Guilin to Yangshuo? How long does the journey take and how's the fare?

I'm afraid you can only take a ship to enjoy the scenery from Guilin to Yangshuo. The whole journey takes about 4.5 h. And it costs about CNY 210 per person.
As for the bamboo draft trip, it operates between Yangdi, Yangsho County and Xingping. You can enjoy it for about 1 h. And it costs about CNY 100-120 per person.
