Guang Xi, being the neighbor of Vietnam, is all the way in the south in China. Most of the time it's known probably for the Li River. However, the weather isn't that great except probably in fall, otherwise it's humid and/or hot and cloudy most of the time. The rice terrace in Longsheng is fairly nice, especially when it's full of water (unfortunately I went there a couple of weeks earlier before they water the rice terrace).
