On google map there is Langdong Bus Station Ticket Office at You'ai S Rd, Xingning Qu, Nanning.

And the other is Langdong Bus Station Qingxiu, China.
If i want to purchase the bus ticket to Detian Waterfall, which station should i purchase it at? And what is the difference between two areas as they seem to be quite far apart from each other.

Hopeful for quick answers! thank you in advance :)
