Despite all that natural beauty, I did not take many landscape pictures, because it was permanently hazy throughout our trip. Leading to very boring even grey images. There were a few exceptions, where the haze actually lent a beautiful atmosphere itself. The shot above is an example.
It was taken at the green arrow in the satellite image below. It's taken in South East direction, so you'll need to move the map to see the mountains it depicts.
On the map you can see the strange karst landscape in the highlands. Think Ha Long Bay without the water. Or, as far as I can judge from pictures, from the more famous karst in Yunnan, China. (The border to Yunnan is about 2mi away from this point.)
