Guilin is a city in North Guangxi, China. Guilin is a scenic town and one of the best-known tourist destinations in China. The town center is surrounded by two rivers and four lakes and studded with sheer sided karst mountains. What makes it special is its proximity to many picturesque limestone mountains and formations. http://wikitravel.org/en/North_Guangxi
Yangshuo is popular among tourists for its karst peaks, rivers, caves, and temples as well as its laid back cafes and bars. The main reason people stop in the town is to explore the local countryside by bike, try their hand on the world class rock-climbing sites or take a bamboo raft down the river, viewing the famous ¥20 scene in the process. http://wikitravel.org/en/Yangshuo
