In the southeast of Houzhen, Chicheng County, Zhangjiakou City, Hebei Province, there is a skyscraper more than 600 meters high. In history, it is known as "the first peak of secluded swallow", "the first stone in the world" and "the largest Danxia in the north".
Danxia landform belongs to red bed landform and is a horizontal structural landform. The rock wall is named "Red Cliff" because it is red, and there are often caves along the horizon on the wall.
Refers to isolated peaks and steep rocks formed by long-term weathering, stripping and water erosion of red sandstone. It is the general name of various Danxia peaks developed along vertical joints in thick red sandstone and conglomerate layers.
The development of Danxia landform began with Himalayan movement in the Late Tertiary. It is mainly distributed in China, the western United States, Central Europe and Australia, among which China is the most widely distributed and Danxia Mountain in Guangdong is the largest, with the most typical development, the most complete types, the most abundant forms and the most beautiful scenery. This terrain is the most typical in Danxia Mountain in northern Guangdong, so it is called Danxia terrain.
Houchibi, adjacent to Yanqing, is about 140 km away from Beijing. It is the closest Danxia landform to Beijing and is known as the third largest rock in the world and the first in Asia.
The local villagers call it Changyu (a long and high mountain), commonly known as "big stone". It is steep on three sides, sharp as a knife and magnificent. It stretches for more than 40 miles from south to north. The peak is flat, with the highest altitude of1330m. Sunrise and sunset, the mountains are crimson, so it is called "Red Cliff".
In recent years, Houcheng Chibi has gradually become a punching place for online celebrities who drive, ride and hike in western Beijing, which has driven the nearby tourism market.
Today, I will focus on the Great Wall site here. After leaving Beijing via Baihebao in Yanqing, the Great Wall is divided into two branches in Houzhen area. One branch line goes directly from Houzhen to Zhangjiakou in the west, and the other branch line goes north along Longmen Station to Dushikou. Then he turned a big bend at Dushikou, returned to Chongli and joined another branch of Zhangjiakou. In this way, this section of the Great Wall is a triangle in Chicheng County.
Chicheng has been an important military place since ancient times, and there have been wars in history. The Yuan Dynasty became the main post road connecting merchants and metropolises, and the Ming Dynasty was called the "Gyeonggi Barrier" to protect Beijing. Zhangjiakou is commonly known as the Great Wall Museum. According to historical research, the Chicheng section of the Great Wall in the Northern Wei and Northern Qi Dynasties is about 690 Li, accounting for 1/4 of the Great Wall in Zhangjiakou.
In addition to the Great Wall, there are ancient castles scattered in various canyons. 40 kilometers north of Houchibi is the famous extended bunker. The expanded bunker is located in a dangerous place, in a deep valley between the inspection department and Ningjiangbao. It is a transportation hub from Dushikou to the Great Wall on the East Road.
The "Luzhenlou" on the west side of the canyon is the commanding height of the whole extended bunker, where you can observe the enemy's situation in all directions. When you climb upstairs, you can see a panoramic view of the whole long beach. The castle is divided into two cities, the northern city is the garrison area and residential area, and the southern city is the school military field.
As for the origin of the levee, it is said that in ancient times there was a military commander named Chang who guarded this place and was invincible. This fortress is impregnable, and it is called the land of constant victory. Later, it was mistaken for a long paragraph.
Houcheng Chibi westbound, passing Dongxing Fort, Diaoe Town and Sanchakou to Longguan Town. You can see the ruins of the Great Wall during the Warring States Period.
Dongxing Fort is an important gateway for Mongolians in the north to go south in Ming Dynasty. Therefore, not only the Great Wall has been built in this area, but also castles are scattered in key places of the pass. All the walls around the castle are generally located in the valley.
According to the survey data,
In view of this, the Ming Dynasty built a section of the Great Wall between the north of Longyong and the south edge of Dushi Road. This section of the Great Wall starts from dishuiya, the back town of Chicheng today, and connects with Diaoe, Sanchakou, Longmen Pass and Qiansuo in the west, and reaches Dajianshan and the newly-built city wall in the north. It was built on the site of the Great Wall in the Northern Wei Dynasty, about 169 Li Long.
Further west is Qingping Loukou, which is one of the passes of the Foreign Minister's City in the Ming Dynasty. It is reported that this section of the Great Wall is made of stone. The bottom of the wall is 3 meters wide and the highest point is 3 meters. Most of them have collapsed. Now there are cornfields on both sides of the Great Wall.
At the entrance of the Great Wall of Qingping Building, there is a bluestone tablet, which stood in the winter of the 11th year of Guangxu (1885) and recorded the repair of the entrance of Qingping Building at that time.
The Great Wall of the Ming Dynasty was not built much in the Qing Dynasty, but the Great Wall at the entrance of Qingping was built once, leaving a monument, which is really precious. Now this stone tablet splits in two and falls under this pine tree.
A hollow enemy tower on the top of the South Mountain in Qingloukou is square, with a side length of10m, a height of10m and a base height of1.25m.. It is made of stone, and its body is made of brick.
There is an arch at the bottom of the enemy's east side, and there are two brick carvings 0.2 meters square embedded in the middle of the four sides of the platform. A stone tablet was originally embedded in the forehead of the North Building, but now it has fallen off.
Standing on the top of the mountain, you can see the continuous Great Wall winding up along the ridge. Although it is just a pile of rubble, it still looks like the Great Wall from a distance.
