There are a lot of buses going directly to Qipanjing, the terminus is the Wuhai Railway Station, the fare is about 10 yuan. Or take the No. 5 bus (the terminus is also at the train station) to "Hainan", the fare is 4.5 yuan. In Hainan, you can transfer to the bus in Qipanjing. It's very convenient.
If you do not understand, get on the bus and ask, people here are very honest.
Also there are a lot of cabs, which you can usually share. Lots of them in Hainan. There are also ones at the Wuhai train station.
What's not to worry about? Just ask. Every single person in Wuhai will help you. Oh.
