This city is on the UNESCO list, along Hue, Lijiang and Dali, but from all I definetely like it the most. It is small. There are 3 main streets running parallel with the river. Yes, they looks like shopping alleys, but still it is interesting. There is a covered japanese bridge and few old trade houses beautiful maintained. The river along the city is actually picturesque a coupe of kilometers downstream. It has a very relaxing atmosphere.
