Keyan in Shaoxing is famous for its stone scenery. In particular, a piece of stone called "cloud bone", straight into the sky from the ground, wide and narrow, only 4 meters at the bottom, called a must, known as "the world's first stone." The history of Ke Yan can be traced back to the Han Dynasty. About 1800 years ago, it was still a quarry. The quality of Shaoxing's stone is good. Now there are several scenic spots in Shaoxing developed on the basis of quarry. From the beginning of the Three Kingdoms period and more than 400 years later, a large mountain of Keshan was dug up. This is a scenic spot dug by hand. During the reign of the Tang and the Tang Dynasties, the three generations of stone granules of the grandparents and grandsons have been excavated into a strange stone "cloud bone" and a carved Maitreya stone Buddha. Today is the most eye-catching attraction in the Keyan scenic spot. Puzhao Temple is a Tang Dynasty-style temple built on the mountain, just beside the cloud. With the embellishment of natural landscapes and the involvement of religious culture, coupled with the narration of literati and ink, in the Qing Dynasty, the famous "Keyan Eight Scenes" has been formed. Keyan mountains and rivers reflect each other, the forests are lush all year round, and the stone bridge boats are beautiful, with the unique beauty of Jiangnan. The lake is slowly strolling on the awning boat. The ancient stage in the water is the most lively place in the ancient Shaoxing festival. Lu Xun has many descriptions in the novel.
