Introduction to Sanyi Stone: Jianglang Mountain is a typical Danxia landform in my country. The main peak, Sanyi Stone, is 824 meters above sea level. The three stone peaks are arranged in a Sichuan shape and are called Langfeng, Yafeng and Lingfeng respectively. The peak body is towering, shaped like a sky pillar. There are large and small alleys for access between the peaks and rocks. Among them, Langfeng Peak has an average slope of 88 degrees. There are more than 3,500 stone steps carved along the stone wall. It can be climbed up to about one kilometer in a zigzag way. Reach the top. Standing on the top of the peak, with smoke and clouds lingering at your feet, and a panoramic view of hundreds of miles of mountains and rivers, you feel like you have ascended to the sky, which is refreshing and refreshing.
