Introduction to Diaoyan Cave: The cave is composed of a mountain wall and a boulder. The boulder is the top, one side is embedded in the stone wall, and there are three rocks under the boulder as supports. The cave is in the shape of a crack, with the highest point about 6 meters, the width about 10 meters, and the deepest point about 15 meters. Since the mountain vegetation is better, there are more vines at the entrance of the cave, which cover both ends of the cave entrance. Therefore, the cave entrance looks round from the outside and is integrated with the mountain, making it difficult to find. The entire cave tilts and shrinks inward. The entrance is large but the inside is small. The area inside the cave is about 50 square meters. The inside of the cave is humid, the ground is uneven and tilted, and there are sand and stones on the ground. There is a stone platform built during the artificial period on one side of the cave, covering an area of about 5 square meters and with a flat surface. It is said that it was the place where the Red Army slept. There is a stream at the bottom of the cave, which turns around and passes through the corner of the stone platform before slowly flowing out of the cave. Because the Red Army lived in this cave during the Anti-Japanese War, it was also called the Red Army Cave locally.
