The people who went to the Qingming Dynasty from the back of the mountain were very few and the air was fresh. After arriving at the natural cave, more people began to grow. The cave is very cool and not fully developed. But it is still spectacular. We should pay attention to safety. Some small black holes are not marked, so it is troublesome to step in. Out of the cave to the front of the mountain, a lot of people, good scenery and many mountains have water and stairs.
