Introduction to Qiyun Cave: Qiyun Cave is a natural stone cave, about 3 meters high, with a narrow mouth and a wide inside, dim light, and many inscriptions from different dynasties. It is a treasure house of Chinese calligraphy art. There is an ancient well called "Chengxin" in the cave. The spring water is particularly sweet and delicious. If used to brew "Seven Realms Green Tea", the aroma will overflow and refresh the spleen and lungs. What is even more valuable in the cave are the bluestone statues of the 18 Arhats, which vary in height and size, but all have simple and rough lines. On the Buddhist platform dedicated to Arhats, there is a message: "The bhikkhu who lives in the mountain has a good heart and wishes to recruit ten nine Tanana seats. Each of them gave up seven coins to make a second statue of Guanyin Bodhisattva, and eight eight seats were placed on the living Arhat platform to enshrine and support him. At the age of Wushen On the 12th day of the 9th month of the 8th year of Chunyou, the stonemason Chen Zengyuan made the inscription. The eighth year of Song Chunyou's reign is 1248 AD, which is 750 years ago. It is said that there were only 16 Arhats before the Tang Dynasty, and "Venerable Qingyou" and "Venerable Bintulu" were added in the Song Dynasty.
