Explain in detail one of the four famous caves in China: Jiangle Yuhua Cave.

Karst caves that we seldom see are usually full of mysterious colors. The beauty of caves in China's famous scenic spots is very attractive, which is always presented to people with incredible beauty under the ingenious nature. There is a Yuhua Cave in Fujian, which is known as the "Pearl under Wuyi Mountain". Let's have a look.

Yuhua Cave Scenic Area is located at the foot of day order Mountain, 7 kilometers south of Jiangle County. The total length of the whole tunnel is 10 Li, and the main tunnel is 5 Li Long. It is the longest and largest limestone cave in Fujian Province, because the rocks in the cave are as smooth as jade. There are two passages in Yuhua Cave, which are divided into six sects: Why, Leigong, Guo, Yuan and Baiyun. There are three springs in the cave: Shiquan, Jing Quan and Lingquan, which are sweet and gurgling. There are Dharma side walls, immortal fields, underground Dragon Palace, and? What? There are more than 160 scenic spots, such as fruitful and even changing days. Many cliff stone carvings since the Song Dynasty have been preserved in the front and back caves and the rock walls in the caves. Shi Yang, a famous Neo-Confucianist in Song Dynasty, and Li Gang, a national hero, have been to this cave. Xu Xiake, a geographer in the Ming Dynasty, praised that "this cave is dazzling, ingenious and secluded, revealing layers of jade and clouds."

Import is a "wind", and the wind never stops. The mountain pass is a "five-watch day", and you can appreciate how dark it is to turn into dawn. There are two energy channels in the cave, which are divided into six sub-caves: five grains, fruit, yellow mud, Leigong, Xiyuan and Baiyun. There are three streams in the cave: Shiquan, Jin Quan and Lingquan, which are as clear as a mirror. There are also Qionglou Yuyu, Kelong Drinking Water, Penglai Diecui, Chaotian Xiao, Eagle Independence, and the wind drifting with tears, all of which are special hall scenery formed by limestone dissolution. Among them, the images of immortal field, litchi column, blast furnace, black dragon going out to sea and boy worshiping Guanyin are the most realistic.

The road in the cave is flat, the hall is spacious, the stone steps are built on the slope, the small bridge crosses the stream, and the path is winding, which is amazing and unpredictable, just like a maze. The temperature in the cave is about 10 degrees, which is warm in winter and cool in summer. Shi Yang, a Neo-Confucianism scholar in the Song Dynasty, and Li Gang, a famous scholar who resisted gold, once praised "this cave is wonderful and secluded" and "there are layers of jade and clouds in the dew". On the rock wall at the entrance and exit of Yuhua Cave, there are many cliff carvings in the Song Dynasty. The path, creek bridge and stone steps in the cave have been trimmed and widened, and colored lights have been installed to illuminate the cave, which is completely new.

The deep Yuhua Cave is a "natural hospital" for implementing cave therapy. The temperature in the cave is kept at 18 degrees all the year round, with cool breeze and fresh air. Its front hole is low and narrow to the northwest, and its back hole is high and wide to the southwest. In hot summer, the air in the back hole sinks and ejects from the front hole. In winter, the cold air in the front hole rises and ejects from the back hole. The wind force in the front hole reaches level 4, which is a famous "wind".

Yuhua Cave is not only a natural "cave oxygen bar" with pleasant scenery, fresh air and a small amount of microorganisms, which is close to the clean air of the forest. In the long years, ancient caves have experienced many strong crustal movements, and every time the crust rises, new caves are formed. 1997, when experts from the Ministry of Construction visited Yuhua Cave, they pointed out that Yuhua Cave is a young limestone cave, which is in the period of growth and development, thus showing the tourism value of this ancient cave.
