Thousands of years of deposit, only for one encounter. Dazzling and strange, all over the Youao. Come to Yuhua Cave to explore the secret~ It's really beautiful. In the early morning of winter (about 9:50 into the cave), there are not many people, the itinerary experience is very good, after about an hour, see the wonders of nature~p.s. Guilin Reed Flute Rock, Fujian Yuhua Cave, Hangzhou Yulin Cave, Beijing Shihua Cave and called China's four major karst caves.
