Several years ago, I visited the town of Yangshuo which is part of Guilin, located in Guanxi Province of southern China. Yangshuo is famous for its scenery, especially the karst peaks. Many visitors to Yangshuo come from Guilin by boat along the scenic Li River which is a great way to travel and enjoy the Chinese countryside.
In addition to the countryside scenery (and ripoff shopping experience if you're into that), another fun thing to do is attend an outdoor performance called Impression Liu Sanjie which was co-produced by famous Chinese film director Zhang Yimou. The performance is an incredible experience, with the audience seated in front of a river and mountain. Most of the show is acted out by about 600 singers and dancers on the water with the mountain providing the background.
Here's YouTube clip of part of the Liu Sanjie show
Yangshuo isn't one of the best known places in China and its quite a distance for most foreign visitors who stick to Beijing, Shanghai and other more northern oriented cities, but its certainly worth a short visit if you're in Guilin (which makes a nice sidetrip from Hong Kong or Shenzhen).
