贵州深山竟发现一个天下第一高洞，垂直高度高达215米，太壮观了！︱The world's highest cave in Guizhou is 215 meters high.

Deep in the mountains of Qunshan County, Huishui County, Guizhou Province, there is a wonder called the world's first high-altitude cave water, the Yanzidong Cave. The vertical height of the cave is 215 meters, and the width is more than 50 meters. It's like a gap that the sky and the earth tear apart. The cave is divided into three layers, the space is narrow, the underground river is winding, and the depth is unimaginable. Standing in front of the cave, you can't help but feel the smallness of human beings. You feel that you will be swallowed by the darkness in the next second. Every spring, hundreds of thousands of swallows come back naturally to nest in the cave. In autumn, with the new swallows, the total size can reach nearly a million. However, if you really want to walk into this Yanzidong Cave, and feel the magic of nature, it's not easy. You have to walk about two kilometers in the mountains first, then cross an iron bridge. Because of the flood, there are only two iron chains left. This is like a test to the fate. Every step makes people's hearts beat faster. Every look is full of admiration. This is not only a geological wonder, but also a land of life. It is a treasure given to Guizhou by nature. Let's follow our camera to walk into this secret cave and feel the natural miracle that only belongs to Guizhou. Hello, everyone. I'm Xue. Now we are near Yanzidong. The car can only stop at the bridge opposite us. If you want to come here, you can go straight to Guizhou Huishui Yanzidong Scenic Area. From here to Yanzidong, it takes about two kilometers. It's our first time here. Let's follow our camera to have a look. This is a very beautiful walking route. There are no tickets for now. There is a river next to us. Wow, look. The ecology here is really super good. The river is green. This river is called the Bawang River. Its water source flows from Yanzidong. We can find Yanzidong just by following this river. Walking in such a forest, I can hear the sound of insects and birds. The forest cover is very dense. The air is very fresh. Being in such an environment, even breathing is a kind of enjoyment. There is a stream here. The water flows down from the mountain. Although the mountain is higher in Guizhou, it never cuts the water. Wow, the water is so clean. It's crystal clear. I really want to swim in this weather. This is a forest. It's really cool to walk in here. A cool breeze is blowing. There are some belts on the trees. I think they are for outdoor runners. Look here. There is a raft here. If you come out of Yanzidong and don't want to walk, you can take this raft. It will save a lot of energy. There is a sign here. It's 10 yuan per person for today's travel. It's 10 yuan to Maoli Bridge from Xilong Cave. It's quite cheap. Maoli Bridge is where we first came from. Our car is parked next to Maoli Bridge. Wow, look. This is the first cave we met on the way. It's called Xilong Cave. There are two paths to choose from here. One is to cross the Xilong Cave. But the water is a bit deep today. It's impossible to walk on this waterway. There is a small path next to the Xilong Cave. But we have to take a detour. There seems to be no other choice. We can only take this path. The Xilong Cave is a passage. We can see it clearly from this angle. There is sunlight outside the cave. There are monsters in the cave. Actually, we really want to go through this cave. You can see that the water level is very high. And the path is not easy to walk. So, for safety, we still take this path. There is a small path here. This path leads to the Xilong Cave. When the water level is low, people often take this path. Oh my god. It's so beautiful here. In front of us is the Swallow Cave. But now we are on the side of the Swallow Cave. We can only see a little bit of the entrance. We still have to walk from here to the valley. Then we have to walk through an iron bridge. We have to walk a long way to get there. Now let's go down. Wow, there is a small cave here. There is water everywhere on the mountain. The water is so cold. The clean water can be used directly. The water quality here is also very rich. Now we have reached the location of the suspension bridge. These two girls are walking in front of us. They don't dare to go there. Have you passed by? No. Don't imitate us easily. Because we can swim. This suspension bridge was originally paved with wood. But the wood was washed away by the water. We have to go through this one by one. Otherwise, both sides of the suspension bridge will collapse. We have reached the middle. I feel that this side of the suspension bridge is very narrow. The water here is a little deeper. I feel that every step I take is a step. This is a little more shaky than the previous one. And the water level here is a little deeper. I have heard the sound of my heart. Oh my god, I'm finally here. The narrow heart has finally fallen. These two girls have been hesitating for a long time. They are determined to come here when they see me. You have to take a big step first. Then you have to lie down. Her feet are shaking all the time. This girl has finally arrived. How do you feel? I don't dare to look at the water. You don't dare to look at the water. I feel dizzy when I look at the water. I don't dare to look at the water. Me too. I don't dare to look at the water. I feel a little dizzy. I don't dare to look at the water. I feel a little dizzy. We have all come here. The two girls have also come here. Now we are going to the swallow cave to explore the cave. Oh my god, this is so spectacular. This kind of red is less common. This kind of yellow is still rare. In fact, just now, when I came here, If we come from the other side, we can also come here. The water here is relatively shallow. The vertical height is 215 meters. Its width is more than 50 meters. It is the highest cave in the world at present. It also holds the title of the world's first high-altitude cave. I feel so small when I stand here. I can't feel the water from the river directly. The water flows from this cave. It's the first time I've seen such a big river flow out of this cave. It's so spectacular. We have arrived at the entrance of the swallow cave. Look at the water dripping everywhere on this cliff. It's like a rain. These stones are flushed out by the river. We have to climb up from here. Can you see the yellow things on the ground? Isn't this you? This is the face of the swallow. We have to climb up from here. The reason why this cave is called the swallow cave is that In the spring of each year, 400,000 to 500,000 swallows will come here to graze. Do you see the stairs on the cliff? This ladder was built by an entrepreneur. They built it for the convenience of picking swallows. There are swallows' feces on the ground. There are a lot of feathers on the ground. We can keep going inside. Let's explore the cave. Oh my god. There are swallows' feces in this cave. It's piled up like a mountain. It's so smelly in here. There are more inside. Have you been to the deepest part? No. I'm a little scared. There are more inside. What is the bag for? It's for swallows' feces. Two girls told us that if we go straight from here, there is a cliff. We have to go down from here. This cave is divided into underground cave, mid-level stone wall, and high-altitude cliff. It's full of rubble. I don't know if we can go there. The ditch on the stone wall is made by the water. It looks strange. I went up there and looked inside the bag. There are swallows' feces in the bag. Maybe some people need the feces to feed the swallows. We can't go up there. It's too steep. Let's see if we can go there. The cave is full of rubble. The feces are accumulated over the years. It's a very thick layer. I can't hold the wall. No matter where I hold it, it's all dead. I'm afraid the swallows' feces will fall on my head. It's really terrible. Actually, I don't need to say more. You can feel it. You can feel the smell. It doesn't smell bad. How can I put it? It makes your nose uncomfortable. You can't breathe well. I have to admire the great work of nature. Look at the cave. It's so strange. It's amazing that such a big dark river flows out of the ground. This is the cliff. We can't go there. Because we are not professional cave explorers. This is what it looks like. Look at my feet. It's a thick layer of rubble. Let's go out now. It's really hard to say. There's rubble everywhere. Oh, my God. It's really high up here. Look. It's at least 100 meters. We've already visited it. Overall, it's pretty good. It's worth a visit. The scenery here is really beautiful. The photos are also very good. You can come here and feel the great work of nature. It's really amazing. Of course, except for the swallow's nest. Because this place is not developed. So if you come here to play, you must pay attention to safety. Okay, that's it for today. See you next time. Bye. Bye.
