This is the first time I have seen such a well-preserved ancient Shiju site carved out of extremely hard granite."Guyaju" has not been accurately recorded in historical records and is a mystery that has never been found in China. The largest cliff ju site has been discovered so far. It is low-key hidden in the canyon at the foot of Haituo Mountain in the west of Yanqing District, Beijing City, about 20 kilometers away from Yanqing District. Haituo Mountain is also the second highest peak in Beijing at an altitude of 2241 meters. The drizzling rain that day was just suitable for exploring the ancient world. The tranquility of the mountains seemed as if the two of us were the only ones in the scenic area. Not only was the impact of the epidemic, it seemed that there were some small groups. The Internet celebrity card didn't reach here.

The scenic area is clean and tidy in the green shade, and the tour route signs are clearly positioned to point to the "meter" unit. The temperature in the valley is a few degrees lower than that in the city and is very cool. The ancient stone houses are distributed on a cliff of 100,000 square meters and are divided into three areas: front, middle and back. Almost every area seems to be created on a huge piece of rock, and it follows the direction of the original joints of granite. It also appears to be scattered and scattered, and I admire the magic and majesty of the ancients fighting against heaven and earth for survival and reproduction.

How to choose a place to live is suitable for survival and avoid risk invasion."Ancient Cliff Residence" occupies a hidden, sunny, leeward and has a water source. There are 137 stone chambers in total. Each stone chamber has a different spatial structure, has a public passage and is relatively independent. The indoor functional area is designed to have kitchens, bedrooms, and stables. Large and small niches dug on the walls should be used to store objects. The amount of work required to dig on hard rocks is huge. With the excavation tools at that time, it was time-consuming and laborious.

There are parallel suites and unimaginable duplex two-story floors. During the tour, I found a hole that looked like a window but had no door. When I entered, I found the "upstairs and downstairs" with flat walls. It was not easy to pay attention to it. The largest three-bedroom apartment was 7.45 meters wide and 3.5 meters deep. It was already luxurious at that time and you could go in and see what happened. Some grottoes still supported metal shelves inside for long-term preservation.

In the community, you can also see a relatively independent household with doors and corridors. The layout is like a suite with privacy. It is estimated that it is a tribal leader or a large household. There is also a separate stone ladder in front of the door leading directly from the bottom of the cliff. The separation is more obvious, and different from other rooms adjacent to it. Although we don't know the social living structure at that time, there will also be classes.

The height and width of the door of each stone house seem relatively cramped. Perhaps the height of the ancients was far less than that of modern people or other defense needs. There are also several holes that open to the outside and should be places for public activities. For example, the door of the shanzhai is engraved with "Chaoyang Cave","Chunyin Tea House" and the like, or it is used for reception or rest. The shanzhai door has not been preserved.

There are some hypotheses that this place may be cultural relics of ancient ethnic minorities. The most influential one is the theory of "Xi People". The "Xi People" were a northern minority in ancient China and a branch of the Donghu Xianbei tribe. Therefore, the appearance of the preserved "Xi Palace" looks even more beautiful. The inscription is the largest and most complex cliff residence in the area. It is likely a place for discussion, gatherings, and sacrifices. In today's words, it is the "government office" and is protected by fences. It is not allowed to enter and visit.

There are also "wind erosion niches" on the rocks, which are different from artificially dug caves. The shape of the edges is naturally formed and has no direction or arrangement. The ancient well is the source of water for life and production in the whole village. There are also "Longquan" and "Elephant Spring" that use water sources. During the mountain climbing, there was a stone carved with "Elephant Spring" at a corner, but the location of the spring hole was not found. Perhaps it was buried deep. Birdsong Mountain is more secluded. You can often encounter small squirrels scurrying in and out of the canyon, and their cries are very green. I heard squirrels chirping up close for the first time, and I saw that there were no other birds around me that I was convinced that it was singing without scruples, how peaceful the ecology is.

Standing high on Qianshan and leaning against the railing, I can see a cluster of red-roofed villas outside the pine forest, a church and the Guanting Reservoir in the distance, which is like a quiet lake. It is a picture of modern living in groups, but the clarity of the photos taken in the light rain is not very high. In sharp contrast to the ancient tribes of stone caves, it is either like a different generation, or it is already a different generation.

The "Ancient Cliff Residence" can be visited in more than an hour, and the relatively concentrated steps in the front, middle and back areas are completely won out by the leisurely and leisurely construction of the steps. Tickets are 54 yuan/person, and 60 years old (inclusive) are free of charge. We enjoyed them properly. The scenic area was really difficult. It seemed that the tourists were just us at that time. The parking lot is relatively large and convenient in front of the ticket office. The parking fee for small cars is 10 yuan/car without counting. I suggest that it is 28 kilometers away from the Badaling Great Wall, so you can take advantage of a day's trip.
