history

Cao Cao's underground military transportation road, with Dayu head as the center, extends to all sides and reaches the outside of the city respectively. The whole tunnel is crisscross, the layout is mysterious, the three-dimensional distribution, the structure is complex, and the project is huge. With a length of more than 4000 meters, Yunbing road is the earliest and largest underground military battle road ever discovered. In July 1986, it was announced as a key cultural relics protection unit by the provincial government. According to historical records, Cao Cao used tunnel tactics many times to win the war. The ancient underground road in Bozhou was the underground military defense road built by Cao Cao in his hometown. He secretly sent a small number of soldiers out of the city from the tunnel, and then drove into the city from the outside. He repeatedly bewildered the enemy and won by surprise.

structure

There are three types of existing ancient tunnels: civil structure, brick soil structure and brick structure. There are four forms: one-way road, turning Road, parallel double road and two-story road. The tunnel is generally two to four meters away from the ground, with a maximum depth of seven meters, a height of about 1.8 meters, a width of 0.7 meters, and a "t" shape at the corner. The distance between the two parallel roads is 2-3.5 meters. There is a square communication hole in the middle, which is deep and winding. There are military facilities such as cat hole, shelter, barrier voucher, barrier wall, trip leg board, trap and other ancillary facilities such as air vent, communication hole, lamp niche and so on.

There are many relics unearthed in the road, such as bullets, swords, lanterns, bronze mirrors, pottery, porcelain, inkstones and so on, which are of great significance to the study of ancient Chinese military architecture, military tactics and Cao Cao's military thought.

Scenic spots

ShuoLong border underground Great Wall

ShuoLong "underground Great Wall of Frontier" was originally an underground artillery fortification, later renamed "underground Great Wall of Frontier". It is located on ShuoLong street, ShuoLong Town, Daxin County, about 12 kilometers east of the famous scenic spot, Detian waterfall. Built in the late 1970s, the "underground Great Wall at the border" is made of reinforced concrete, which is hidden several meters deep underground around ShuoLong street. The engineering design is scientific, the layout is reasonable, the tunnels crisscross, and connect with the surrounding mountains, niling boundary river, and civil buildings, which has the functions of air defense, artillery defense, and avoiding war. The whole project took thousands of migrant workers to dig tunnels and caves. It took several years to complete.

Walking into the entrance of the underground Great Wall at the foot of the mountain on the left side of ShuoLong street, the tunnel is arched, about 2 meters high and 1.5 meters wide. The wall of the tunnel is solid, smooth and dry. Walking about 20 meters inside, you can see a stone step. You can climb up to the highest part of the mountain, and you can see the tunnel's lookout tower. The view here is very wide. You can see all the roads across the Guichun River and into ShuoLong street. Every corner of ShuoLong street is also within your sight. If there is an enemy of invasion, it will be completely exposed, even if he has no return.

Walking along the winding tunnel, you can see the tunnel sentry posts which lead to the ground not far away. They are scattered and very hidden. Inside, you can clearly observe the situation outside, but it is difficult to find these entrances from the outside. Further on, there is an "exhibition room for pictures of defending the border and defending the enemy in the past dynasties.". Along the way, there are weapons and ammunition depot, military supplies room, wartime underground hospital and other facilities, as well as a relatively spacious wartime residential room, which is a safe place for local residents to escape the war. What's more ingenious is that some underground residential rooms are connected with the rooms on the ground. They enter the tunnels during the war and go to the houses after the war. They are flexible, safe and fast. The exits of the tunnels extend in all directions. Some are at the foot of the mountains, and some are in the streets. It's very secret.

Guangxi underground Great Wall

Pinggangling underground Great Wall was built in 1889. It was a military defense system built by Su Yuanchun, Guangxi frontier commander in the late Qing Dynasty, when he supervised Guangxi frontier military affairs. According to the terrain of pinger River, which is the boundary river between China and Vietnam, it built two artillery turrets in the north and south of pinggangling, with one German Krupp cannon and several small guns. In 1921, Beitai artillery was moved to "Zhenning fort" in Nanning by Guangxi warlord Lu Rongting. Between the north and South battery connected by the grand underground passage, and straight to the river, more than 1000 meters in length, so it is called "underground Great Wall". Pinggangling Fort left a brilliant page in the war of resistance against France, the war of liberation and the war of aiding Vietnam and resisting the United States.

In February 1950, the 134th division of the 45th army of the people's Liberation Army intercepted the remnant troops of the Kuomintang in pinggangling and pingerguan. After two days and nights of fierce fighting, it completely annihilated the remnant troops of Bai Chongxi in Guixi and 6715 people in the 100th army, 19th division and 197th division of the Kuomintang. This was the last battle in southern Guangxi in the war of liberation, which was called pingerguan battle in history.

Hebei underground Great Wall

Zhangjiakou has 1476 kilometers of the great wall of the Warring States, Qin, Han, Northern Wei, Northern Qi, Tang, Jin and Ming Dynasties. It is the provincial city with the largest number of Great Wall preservation in China and is known as the "Great Wall Museum". What is more precious is that there is an underground Great Wall at the north end of Zhangjiakou City, which is the same as the great wall of Ming Dynasty, becoming a beautiful scenery of the mountain city outside the Great Wall.

The underground Great Wall is a civil air defense project with a total length of more than 10 kilometers, starting from dajingmen in the East and reaching Wanquan County in the west at the north end of Zhangjiakou City, which is in the same direction as the Ming Dynasty Great Wall on the West Taiping mountain. This project was built in the 1970s under the situation of "digging deep, accumulating grain extensively, not seeking hegemony". Like the Great Wall on the ground, it is also a military defense project. Civil air defense project is the foundation of national defense

As a part of the project, relying on the civil air defense project to carry out national defense tourism is a new idea, which not only adds new highlights to the tourism industry of Zhangjiakou City, but also helps to maintain the civil air defense project.

The underground Great Wall is a mountain tunnel project. The projects with development and utilization value mainly include:

Dajingmen cinema. Located in the underground of the mountain root on the west side of the memorial archway in Mingde North Street, it is nearly 30 meters away from the street, with a total area of 1968.8 square meters. The main project is 82 meters long and 14 meters wide. Some parts of the project are reinforced by shotcreting, and others are burrows. It is a class III civil air defense project. The Northwest can lead to entrance 12 of dajingmen gate on the north side of Xitaiping mountain, the south to the city's first command post, and the west to Cuiping temple. It has high development and utilization value.

Yuanbaoshan grain depot. Located in ciergou, Yuanbaoshan, dajingmenwai, with a construction area of 5150 square meters and three entrances and exits, it is a wartime grain and oil storage depot with a storage capacity of 7.5 million kg. The project is equipped with diesel generator set and ventilation equipment. The engineering level is grade 3. It is ranked as the highest in North China by provincial civil air defense. It has the conditions for development and utilization.

West Taiping mountain evacuation road project. It runs through the main mountain range of West Taiping mountain, reaching Chaoyang cave in the East and Cuiping nunnery in the west, with a total length of 10814 meters, a building area of 30659 square meters and a usable area of 22840 square meters. There are 12 entrances and exits, with a width of 2 meters and a height of 2.5 meters. All of them are covered with brick concrete structure. The engineering level is grade 3. In particular, the shotcreting method is mostly adopted in the project from entrance 7 to entrance 8 of Cuiping nunnery, which fully reflects the original nature of the cave and is the most ideal for characteristic tourism.

The relevant departments of the municipal government attach great importance to the development and utilization of the underground civil air defense project of dajingmen, and have made plans and seriously implemented them. A stone road will be built at the peach blossom Yingcui stone of jellyfish palace to reach the entrance of the underground Great Wall. At the entrance of the underground Great Wall, a great wall like gate was built. The underground Great Wall is engraved on the boulder at the entrance of the cave. The cliff above the entrance of the cave is engraved with four characters of "underground Great Wall". The underground Great Wall is divided into sightseeing area, leisure area and exploration area.
