When I came to Yinziyan, I was shocked by the karst cave in an instant. All of this is really the work of nature. Yinziyan is a newly developed karst cave landscape in Guilin. It is named for its abundant crystals and glittering rocks like silver. The scenic spot has a beautiful environment, just like a huge natural bonsai, surrounded by mountains. The stalactites in the cave are as high as tens of meters, crystal clear. The stalactite containing quartz and calcite particles refracts silver-like light under the illumination of lamp, so it is called "silver rock" and is known as "wonder of world cave". Although everyone knows that this is the effect of Lantern making, but the visual effect is indeed incomparable, the magic of the creator is vividly reflected here. When you go in, one person issues a brand, which is inductive. Wherever a person goes, the brand begins to be introduced according to your location. This is a good one. You don't need a tour guide with this one. But the air quality inside the cave is not good, the air is not circulating, it is wet and the ground is slippery.
