First of all, nature is magical. First of all, Taotao River of Qingjiang River gathers into a narrow and swift river in Tenglong Cave and flows into the mountainous area. What we often see is water on the ground. This time, we saw the river flowing underground. How did so much water flow underground? Are there any discomforts or changes when fish and other creatures enter the ground? Where will the river flow out? Wait, my heart is full of questions and I need to find answers from nature. Second, we marvel at the size of Tenglong Cave, which is warm in winter and cool in summer. It is said that helicopters can be parked at the entrance. Now there is a hot air balloon at the entrance, and tourists can pay for it. The inside of Tenglong Cave is like an underground city, criss-crossing, with a high ceiling, and you can take a battery car. There are many kinds of lanterns nowadays. Walking in them is like entering a fairyland. It can be seen that there are many caves that have not been explored by people. Will there be more strange mountains and rocks in it? What did ancient people do in caves? What's it like to explore a cave? Because it cannot be explained, is it a myth? Thirdly, there are two performances in the cave: "Laser Show" and "Biography of Yi Shui Li", which romanticize the mythical love story about Tenglong Cave mainly through the characters and stories formed by the laser on the sprayed water, making it more magical to watch in the cave. Yishui Lichuan performed the ethnic customs of Enshi Lichuan through singing and dancing in the cave.
