Ancient cliff dwellings were caves dug on steep cliffs by an unknown group of ancestors. There are 147 stone chambers preserved here, divided into three parts: front, middle and back, hanging on a cliff of about 100,000 square meters. The stone chambers are either facing each other or adjacent to each other, high or low, scattered and well-arranged. The stone chambers are either rectangular or square, the large ones are about 20 square meters, and the small ones are about 3 to 4 square meters. Some are single rooms, and some are connected by 2 to 3 rooms; some suites are parallel, and some are two-story. All the stone chambers are distributed in layers, and there are stone steps, stone ladders and plank roads between the layers. These stone chambers have complete living facilities such as doors, windows, kangs, stoves, mangers, closets, flues, and storage rooms. The windows are generally 2 to 3 square feet, and the doors are large and small. Some can be entered and exited freely, and some can only be climbed in; symmetrical axis holes are chiseled on the top, bottom, left and right of the doors and windows. There are often water chutes chiseled on the front eaves, and the chutes go directly into the room, which may be used to collect water. These stone chambers have different functions. Those with kangs seem to be for living, those with horse troughs seem to be for raising horses, and those with kitchen stoves seem to be kitchens. There are also two types of stone kangs. One is a kang platform carved on granite with no smokeway at the bottom, and the other is a curved road with a back dragon style, on which stone slabs or adobe can be laid. A stone stove is carved on the side of the stone kang, and there is a smokeway under the stove that leads to the kang. It winds around for a few circles and leads to the outside of the stone chamber through a hole in the wall. It looks like a fire kang, and its width can sleep two people. One of the stone chambers is a typical "three-bedroom" layout. The middle room is larger and has a door, which is considered the main room. The room on the right is the kitchen, which has a stone stove and smokeway, which is considered the kitchen, and the room on the left has a closet. The "official hall" is a representative of many stone chambers. It is located in the middle of the mountain beam and is similar to an ancient palace. It is not only tall and spacious, but also has excellent lighting conditions and fine carvings. There are 4 stone pillars in the stone chamber to support the cave ceiling. In the middle of the 4 pillars is a wide Buddhist niche, and 2 small rooms with kangs are carved symmetrically on both sides. The stone chamber of Guyaju has a complex structure and ingenious design. There is no exact record of its excavation age, history, background and purpose in historical books, and it remains a mystery to this day, with experts having different opinions.
