China's excavation of the "underground Great Wall" has not been discovered for 700 years, and it is all military secrets.
In ancient times, various regimes often built landmark buildings in order to protect the world, including some structures of military significance. It's like Qin Shi Huang built the Great Wall to defend against the Xiongnu. These buildings are now well-known tourist attractions and attract tourists. When people are surrounded by these ancient buildings, they cannot help but feel awe of the wisdom and achievements of their ancestors. Despite the lack of modern advanced technology and large machinery, the ancients were still able to accomplish some incredible feats.
In addition to the Great Wall of China, which winds its way to the surface, there is also a section of the Great Wall underground, which has been hidden underground for 700 years. The reason for this is still unknown, but who built this section of the Great Wall?
China has a long history, and its historical sites are numerous, such as the Forbidden City, the Temple of Heaven, etc. Since the founding of the People's Republic of China, these above-ground buildings have been regarded as national key cultural relics protection units, and have been carefully repaired and protected.
However, the discovery of some historic buildings has been quite tortuous. Just like Cao Cao's military transport road, it has been used since the Eastern Han Dynasty and has not been completely forgotten. The latest discovery has been a twist and turn. In 1969, in response to the call of the first generation, people dug underground air-raid shelters one after another, and unexpectedly saw the figure of Cao Cao's troop transport road.
In Jin Yong's ** "The Condor Heroes", the tomb of the living dead in Zhongnan Mountain is famous for its dense mechanism, and the ingenious design of Cao Cao's military transport road is comparable to it, making it almost impossible for people who enter it to get out, which can be called equally terrifying.
When it comes to Cao Cao, I'm afraid everyone knows about it. As an important character in "Romance of the Three Kingdoms", he is as cunning as a fox and has excellent military talents. Having spent most of his life on the battlefield, his military acumen was highly regarded. However, Cao Cao was not only good at frontal combat, he was also good at making stratagems unaware of the enemy, which made him even more elusive.
Cao Cao Road is located in the old city of Haozhou City, Anhui Province, which was a place of frequent wars in the past. At the end of the Eastern Han Dynasty, warlords from all walks of life fought one after another in order to compete for territory, and the situation was grim. In this context, Cao Cao did not hesitate to use all means in order to win the war, and the construction of underground passages was one of them. The use of tunnel tactics has been reflected as early as the Warring States Period, and reached its peak in the War of Resistance Against Japanese Aggression, becoming one of the important tactics in the history of military warfare.
In order to ensure the victory of the war, Cao Cao carefully laid out and spent a lot of manpower and material resources to build the troop transportation road. The whole road is divided into two parts: the watchtower and the ancient tunnel, and its design is ingenious, which won Cao Cao a valuable advantage on the battlefield.
In ancient times, the watchtower was a towering building, according to historical records, its height had reached more than 20 meters. Today, however, a Chinese-style building has been built on the site, with a basement floor and six floors above ground. The upper floor was used to entertain the ministers, and there was a military lookout. Because of its towering momentum, the tower can have a bird's-eye view of the four fields, and it has become an excellent place to observe the topography.
The basement level is the main entrance to the transport. Even when the upstairs feasted and drank, there was a different kind of world hidden downstairs, and the soldiers quietly entered the underground Great Wall through here. Even after the founding of the People's Republic of China, the people of the old city of Bozhou did not know anything about it. Although rumors of Cao Cao's construction of an underground troop transport road have long been circulated, the secret has not been revealed because the actual object has not been seen.
It was not until the 70s of the 20th century that Cao Cao's military transport road was rediscovered. The experts entered the area, and after careful investigation, it was confirmed that the place was centered on Osumi Shou and extended to the outside of the castle. To date, it remains one of the oldest and most well-preserved underground military installations in China, and its influence extends even into the Tang and Song dynasties.
The entire interior of the underground Great Wall is intricate and cleverly laid out, and it is breathtaking. The tunnel is as large as a dungeon, and has been found to be more than 8,000 meters long. Its roads are wide, with one-way streets, parallel double lanes, upper and lower two-story roads, three-dimensional crossings, etc., to meet the different needs of troop transportation.
In addition, there are various mechanisms in the tunnels, such as cat ear holes, obstacle tickets, barrier walls, traps, etc. The command post is located near the double street, with a brick and wood structure, which used to be Cao Cao's office.
It is located above the ground, but like a castle in the sky, in the center of the underground Great Wall, making it easy to get anywhere. Historical data show that after Cao Cao's regime built the troop transportation road, it repeatedly used its tactics of confusing the enemy and winning more with less, making it an important strategic facility for the regime.
By the Tang and Song dynasties, the rulers discovered Cao Cao's military transport route and repaired it, further exerting its military role rather than being buried. Due to the frequent use of the military transport road by the imperial court, the internal structure is no longer confined to the architectural style of the Eastern Han Dynasty, which provides a valuable architectural heritage for future generations, allowing them to understand the history of the time.
Considering that the route involved some military secrets, the relevant information was only known to high-ranking generals, so it was not recorded in the natural history books. However, during the Jiaxi period of the Song Dynasty, due to the rupture of the Yellow River, Cao Cao's military transport road was blocked by a large amount of silt. Since then, the road has been temporarily withdrawn from the stage of history, until it was rediscovered again 700 years later.
In 1938, the site was rediscovered, but due to the chaotic situation at the time, no further excavations were carried out. It was not until later that the relevant departments gradually paid more attention to it, listed it as a national key protection unit, and began to increase its development and repair work.
Inside the transport route, many ancient artifacts were also found, which may have been left behind when people were evacuated in a hurry. These cultural relics are of a wide variety and cover different periods such as the Eastern Han Dynasty, the Three Kingdoms, and the Tang and Song dynasties. Such as iron swords, iron knives and other weapons commonly used on the battlefield, as well as daily necessities such as bronze mirrors, iron lamps, porcelain, etc., these cultural relics have high research value.
Today, the authorities are making constant efforts to protect the Cao Cao Troop Road and improve its facilities. The place has also become a well-known tourist attraction, giving it a new social function. Visitors can learn more about ancient history and feel the wisdom of their ancestors. Coming here is like traveling to another world and exploring the mysteries of thousands of years.
The reason why Cao Cao was able to become a generation of heroes was because he had extraordinary skills and the ability to come up with whimsical ideas, broke people's traditional cognition, and built such an underground Great Wall, which played a great role in changing the battlefield situation at that time. Nowadays, Cao Cao's military transport road is used by people again, which truly embodies the wisdom and value of "predecessors planting trees, and future generations enjoying the shade".
We have always emphasized that the Chinese nation is a great nation, and these splendid buildings are one of the witnesses. Although the ancient construction technology was not developed, through some special wisdom, it successfully overcame various difficulties and opened up new horizons for future generations.
These ancient buildings are not only witnesses to history, but also inspire people to learn this knowledge and apply it to modern architectural practice. This not only saves costs, but also further promotes the ancient architectural culture.
