Caves, stalagmites, stone bridges... The beauty of nature's axe is beyond imagination. Standing in front of this green and shining cave, I not only thought of the scenes and pictures in the tomb notes. It is not the bizarre exaggeration written by the novel, but the experience limits our imagination! Seeing this green cave, I really believe that it is the porch leading to another world! After trekking in the cave, after more than two hours, we finally arrived at the legendary cave ladder. This is an artificial cave that is angled up at 45 degrees. Because the exit of Huangxian Cave is located in the underground dark river, it can only be found from here. It is said that in order to build this ladder, it took a huge amount of manpower and material resources. The ladder is divided into three sections, with more than 600 steps. There is a small platform between each section, which can be used for rest. This ladder is difficult to climb and climbs. It requires both hands and feet. Pay attention to safety when climbing.
