Introduction to Xiguang Cave: The name of Xiguang Cave was written by Wang Liang of the Qing Dynasty. The cave is small and shallow, less than 3 meters high. It can only accommodate a few people, and the cave is relatively dark, which is not enough. Watch. However, there are two cracks at the top of the cave, one of which runs in the east-west direction. Whenever the sun sets, a beam of afterglow shines into the cave through the stone cracks diagonally facing the west. It is brilliant and brilliant, so it is called the Sunset Cave. At the top of the cave, there are two uneven boulders in the shape of conical towers hanging upside down. The tops of the towers face the ground, which are called "upside down twin towers". When looking up at the stone tower, there is an overwhelming and crumbling feeling. Whenever the setting sun slants and the light falls on the top of the tower, it is a spectacle.
