Yangshuo landscapes simply comes from another world. Going along the "Dragon" river is one of the best experiences I've ever had in my life.
The nature is surprisingly wild, after so many days of overcrowded life here there is just quite, from time to time there are little villages, or rather bunch of houses.
Watching and talking with farmers, and observing their lifes going on is really peaceful.
It's difficult to add any more comment, they would never get to the feeling you can experience there anyway. Just try and go there one day, you won't never regret it...
