How to travel to Haikou from Kaiping/ Zhuhai by public bus or express ?

It is suggested to travel from Kaiping to your destination by direct bus at 09:30 and 18:00 every day from Kaiping General Bus Station at No. 28, Xijiao Road, Changsha District, Kaiping. The bus' duration is around 8 hours.
From Zhuhai, the direct buses also exist at 14:15 and 16:15 from Gongbei Long-distance Bus Station.

Thank you very much for your reply. But I like to travel shorter hours to reach my destination. So is maoming to my destination possible by public bus or train?

From Maoming to your destination may take less time by train, but you still need to transfer from Kaiping/ Zhuhai to Maoming by bus.
From Kaiping to Maoming, the bus takes around two hours, while the bus from Zhuhai takes around 3 hours.
So in total, it takes similar time.

Thank you for reply ! I have read the transportation page in your website but it is not specific and detail enough.
if we are to break our journey from Kaiping to my destination, which town is interesting and near to my destination that travelling time to haikou would and how to get there, pls. not be more den 3 hours.

Yanfeng Village Culture Themed Park, about 16km, from the Haikou city is suggested and you are suggested to hire a local car to reach directly.
