Yinziyan is an exemplary karst landform, running through twelve peaks and containing stalactites from different geological ages, all shining like pillars of silver. There is a saying that goes, "Once you've been to Yinziyan, you'll never want for money again." The beauty of this site attracts waves of visitors every year. The underground space is divided into a lower cave, an upper cave and a grand hall between them. As one walks through the cave, the view gradually opens up to hundreds of sparkling silver lights, and the sight becomes even more impressive and unforgettable.
