Introduction to Caiyun Cave: Caiyun Cave is a very deep, peculiar and colorful underground cave beside Huashan Lake. "Crystals flow into waterfalls, jade piles into mountains, rocks freeze into ice, and emeralds form curtains" is a true portrayal of it. The cave is about 3 kilometers long, with a spacious cave body and various side caves. It is generally 20-30 meters wide and high, and is naturally divided into 6 different scenic spots by stalactites. The first hall is relatively spacious and is mainly made of stone curtains and stone waterfalls; the second hall is divided into several layers, with each floor looking like a forest of bamboo shoots and dragon pillars; the third hall is mainly made of stone flowers and stalactites, such as There are many criss-crossing streets, with ten views at a time; the cave in the fourth hall is narrow and eerie; the fifth hall is also known as the Coiled Snake Cave, where there are many python-like things coiled and twisted together, some big, some small, some long, some short, and even There are also snake scales, which are suspected to be python fossils; the stalactites in the sixth hall are as dense as a forest. The rocks in Caiyun Cave are of various colors such as red, white, yellow, black, black, purple and so on. They are colorful and wonderful. There is a spacious hall whose top wall is covered with dark stone stalactites of various sizes and shapes. Between each stalactite is a layer of white minerals. Looking at the reflection of the cave roof from the pool on the ground, it looks like a precipitous tower. The steep peaks are covered with dark vegetation, and the vegetation is covered with mottled white snow, forming a realistic "forest and snowfield" spectacle. The uncanny workmanship of nature is really amazing here.
