Introduction to Tianquan Cave: The famous poet Wang Zengqi wrote in a poem: "The spring comes from outside the sky, and the sky is at the bottom of the cave. There are all kinds of strange things, how can it be here?" This is the peculiarity of Tianquan Cave. The front entrance of Tianquan Cave is located under the northern cliff of Mei Ling, and the rear entrance is halfway up the cliff on the east side of the funnel of Xiaoyan Bay. There are seven connected halls in the cave, each with an area of more than 10,000 meters. They are tall, spacious and magnificent. It is the largest tourist cave in my country in terms of space and length.
