    Guilin is in Guangxi Zhuang Autonomous Region, China, famous of its mountains and waters. I went here last summer and stayed for five day. During that time not only I enjoy the fascinating scenery like the unique mountains and clean rivers, but also I try the traditional weaving of Zhuang people. That impressed me most was the amazing folk-song-singing competition on the Li River, which attracted thousands of visitors or locals. Guilin enjoys a worldwide fame for it beautiful scenery, so it's well worth visiting. I am strongly recommend you to visit it. I believe you will have a wonderfully time.
