Hi..This is my first time at Nanning.Im going there on 29 Oct 2018 - 3 Nov 2018.

But we only have 2 days to explore there which is 30 Oct and 2 Nov 2018.

We would like to go to Detian waterfall, Mingshi scenic area and Sanmenhai National Park for 2 days we had.
We dont want to stay overnight outside the city

Is it possible to go to those places?
Do you know any tour guide agent at the city?
How much price normally?
