The word "Shuanglong Cave" on the west wall of the cave was written by the Tang people. The word "Dong Tian" on the East Wall is Mo Bao of Wu Lin, a calligrapher in the Song Dynasty. The five characters of "36 holes" were written by Yu Youren, a veteran of the Kuomintang and an outstanding calligrapher in modern times. To get into the cave, you must pass through the toad's mouth against the current. The hole is about 3 meters wide and 12 meters long, and the water surface is about one foot from the top of the hole. When visitors enter, they must lie flat on the boat and slowly send them into the cave, with their faces only a few inches from the top of the cave. Strange is fun, and fun is adventure. "There is a spring in the cave, and I want to find the source of the spring and lie on the boat." "The water on the thousands of feet beam is low, and the canoe is lifted up and returned to the stream." This is the unique charm of Shuanglong Cave.
When the boat arrived at the cave, it suddenly became clear. The area of this cave is about 200 square meters. The bottom of the cave is rugged and the top of the cave is undulating. Stalactites on the stone wall and stalagmites on the ground are criss-crossed, grotesque and varied, like figures and objects, with their own styles. Therefore, they were named Huanglong Spitting Water, Frog Stealing Fairy Grass, Camel with One Peak, Tortoise and Snake Born, Longxing Xiantao, Colorful Clouds Covering the Moon, Inverted Bat, Riding on the Sky, Golden Rooster Spreading its Wings, Dragon Tailong Account and Dragon Forest respectively. Among them, "Yellow Dragon Spitting Water" is appreciated by Yu Dafu, a master of modern literature, and is called "Bonsai Waterfall". When Xu Xiake, a great traveler and explorer in Ming Dynasty, visited this cave, he wrote in his travel notes: "The middle is heavy, the land and water are strange, and the secluded and bright are different."
After swimming in the inner hole, turn back to the outer hole, you can go out from a small hole named "Dragon's Ear" in the southeast corner of the outer hole, then turn to the northeast to climb the stairs, and go to Hu Bing Cave via Song Chiting.
