Hi, I want reach Yuangshuo from Shenzhen with a sleeper bus. Do you have the tickets?

Well, about the sleeper bus, there are only two schedules from Futian Bus Station in usual time. One is at 16:30. The other is at 18:40. The ticket fare is CNY 263 per person. Maybe the schedules will be added during the Golden Week. It's suggested to keep close attention on the schedule before leaving.

But the online booking website doesn't have English version. If you have Chinese friends, you can ask help for them. Otherwise, you need to arrive at the bus station early and buy the bus tickets.
