Cloud Cave Introduction: The Cloud Cave has a total length of 8.3 meters and the highest point is 3.5 meters. A hole suddenly opened in the cliff about one meter above the ground. The entrance of the hole is like a toad opening its huge mouth. Looking in from the hole, there is a huge stone in the middle that divides the hole into two parts, and each has its own entrance connected to the outside world. The cave entrance on the left faces the sky, and on the stone wall near the cave entrance are the words "Yundong" inscribed by Wang Tong.
