The most interesting thing about Shuanglong Cave is that there is a huge rock covering the first-class clear spring between the outer hole and the inner hole. The channel is more than a foot wide, and the bottom of the rock is only about a foot above the water. In and out of the inner hole, people have to lie straight on the bottom of the boat. When the ship passed the water at the bottom of the rock, their eyes were dark. It seems that the surrounding rocks are all pushing towards them together, and the rocks almost wipe their noses. About twenty or thirty feet away, it suddenly becomes clear, which is called a spectacle. The inner hole is about 2000 square meters and the hole is deep. When the ship landed, it looked up and saw a blue stalactite pattern winding out from the ceiling of the cave in the northeast, and another yellow stalactite swooped down from the northwest. People call it "Shuanglong". The shape of the dragon is clear and vivid. Stalactites and stalagmites in the cave are grotesque and criss-crossed.
Hu Bingdong's cave faces the sky, with a depth of more than 40 meters. Looking down, the cold came and the hole was bottomless, so it was called "curling". Visitors can step on the stone steps and meander to the bottom of the cave. The waterfall in Hu Bing Cave pours down from the top of the cave about 15 meters high, and the sound of the waterfall is deafening. The entrance of Chaozhen Cave faces west, facing the deep valley in front and facing Qingfeng. Looking in front of the cave, the surrounding peaks stand upright, just like a hundred monks pilgrimage for truth, hence the name of the cave. Stalactites hang high in the cave and stalagmites are everywhere. One stalagmite looks like Guanyin and is called Guanyin. There is a "skylight" above the cave, which lets a beam of sunlight in, just like half a moon, also known as "the shimmer of the sky".
Shuanglong Cave is now a national forest park and a national scenic spot, which is famous for its vast forests, strange caves and famous Taoist mountains. Shuanglong Cave is located in the center of Shuanglong Scenic Area, which is the core and symbol of the whole scenic area. 1600 years, Shuanglong Cave has become a natural scenic spot. It is 520 meters above sea level and consists of outer hole, inner hole and ear hole. The outer hole is spacious, with an area of 1200m2. The annual cave temperature is about 15 degrees Celsius, which is warm in winter and cool in summer. At this point in summer, there is a feeling of "sweating up the mountain and getting cold in the hole". The inner and outer caves are separated by huge stone screens, and only waterways are connected. This waterway is more than ten meters long and three meters wide. The separation and communication between the inner and outer caves form the most distinctive feature of Shuanglong Cave. The ancient poem says, "There is a spring in the cave. If you want to find the source of the spring, lie in the boat." If you want to enter the inner hole from the outer hole, you must lie flat in the boat, wipe the cliff on your back and swim against the current. This is a surprise and full of fun. It is a unique way of sightseeing and has the reputation of "water and stone wonders". The inner hole is slightly larger than the outer hole. If the outer hole is "Dragon Hall", then the inner hole is "Dragon Palace". There are many stalactites and stalagmites in the cave, with unique shapes, clever layout and different colors. There are more than 40 kinds of landscapes, such as "Yellow Dragon Spitting Water", "Inverted Bat", "Colorful Clouds Covering the Moon", "Turtle Exploring the Sea", "Shouxing and Xiantao" and "Frog Stealing Fairy Grass", which make people dizzying.
Shuanglong Cave has a long and splendid history and rich cultural background. Since the Eastern Jin Dynasty, it has been loved by the world. The Tang, Song, Ming and Qing Dynasties were brilliant for several times, and literati poured in. Li Bai, Wang Anshi, Meng Haoran, Su Shi, Li Qingzhao and other historical celebrities all have excellent works. Traveler Xu Xiake wrote more than 4,000 words of travel notes. Modern writers such as Yu Dafu, Ye Shengtao, Guo Moruo and Ai Qing all wrote famous articles for Shuanglong Cave. Party and state leaders, Zhu De, Soong Ching Ling, Peng, and Peng Zhen also left footprints here. There are many famous Mo Bao in the cave.
Stalactites and stalagmites are composed of calcium aggregates. The lime in the cave dissolves in the water, and the lime in the water gathers up bit by bit, gradually forming an ice cone-shaped object at the top of the cave. This is called stalactite, also called stalactite (similar to icicles under the eaves in northern winter). The water at the top of the cave drops to the ground, and the lime gradually gathers and accumulates higher and higher, forming an upright bamboo-like column called stalagmite. Stalagmites are often opposite to stalactites from top to bottom. Over time, some stalactites and stalagmites joined together to form stone pillars. Stalactites and stalagmites have various shapes.
