Introduction to Qingyun Cave: Jizu Chengxian Cave is about three feet deep and runs north-south. The highest point in the cave is nearly 3 meters, and there are traces of manual shoveling on the cave body, possibly by ascetics. When the cave was discovered, simple living facilities and necessities left over from that time were still preserved deep inside the cave, such as a stone kang paved with stone slabs on the ground, pottery drinking utensils, and oil lamps.
