The Great Wall is located in northern China, stretching from Shanhai Pass in the east to Jiayuguan Pass in the west, and is about 6,700 kilometers long, commonly known as the Great Wall of China.
The construction of the Great Wall has lasted for more than 2,000 years. According to historical records, from the seventh century B.C., when the state of Chu built the "Fangcheng", to the Ming Dynasty (1368-1644)*** more than 20 vassal states and feudal dynasties built the Great Wall, of which the lengths of the Great Wall in three dynasties, namely the Qin, the Han, and the Ming, were all more than 5,000 kilometers. If the various times of the Great Wall, the total length of more than 50,000 kilometers; if the construction of the Great Wall of masonry and earth to build a 1-meter-thick, 5-meter-high wall, the wall can be more than a week around the world.
The main project of the Great Wall is a tall wall that stretches for 10,000 miles, mostly built on the highest part of the mountain range, sketching out a clear outline of the winding mountains along the ridges, and shaping the dragon that rushes and leaps with great momentum, thus becoming a symbol of the Chinese nation. On the 10,000-mile city wall, there are hundreds of majestic passes and defiles, and thousands of enemy platforms and beacon towers, which break the monotony of the city wall and make the undulating terrain more majestic and treacherous, and full of great artistic charm.
Among the Great Wall landscapes around the world, the Badaling Great Wall in Beijing is particularly strong and well-preserved, making it the best place to see the Great Wall. There are also the Jinshanling Great Wall, the Mutianyu Great Wall, the Simatai Great Wall and the Gubeikou Great Wall. The Huangyaguan Great Wall in Tianjin, the Shanhaiguan Great Wall in Hebei, and the Jiayuguan Great Wall in Gansu are also famous Great Wall sightseeing spots.
The Great Wall of China is the world's longest construction time, the largest engineering volume of the cold war era of national military defense projects, cohesion of our ancestors' blood, sweat and wisdom, is a symbol of the Chinese nation and pride.
According to historical records, since the Warring States period, more than 20 vassal states and feudal dynasties have built the Great Wall. The earliest one was the state of Chu, which started to build the Great Wall for the defense of the northern nomads or enemy states. Subsequently, Qi, Yan, Wei, Zhao, and Qin started to build their own Great Walls for the same purpose. After Qin united the six countries, Qin Shi Huang sent his famous general Meng Tian to fight against Xiong Nu in the north, and connected the Great Walls of various countries, stretching more than 10,000 miles from Lin Yao in the west to Liaodong in the east, which became known as the Great Wall of 10,000 Miles, and this is the origin of the name of the Great Wall of 10,000 Miles. But what we see today is mainly the Great Wall of the Ming Dynasty.
There are only remnants of the Great Wall of Qin. Qin Shi Huang used 300,000 people to build the Great Wall, creating a miracle in the history of human construction. The construction of the Great Wall objectively played a positive role in preventing the southward invasion of Xiongnu and protecting the economic and cultural development of the Central Plains. Mr. Sun Yat-sen once commented: "Although Emperor Shihuang was not righteous, but the Great Wall has the merit of the future generations, really on the Great Yu water control, etc.".
The Great Wall continued to be built during the Han Dynasty. From Emperor Wen to Emperor Xuan, built a west from the city of Dawan II division, east to the north bank of the Heilongjiang River, the total length of nearly 10,000 kilometers, half of the ancient Silk Road along the Great Wall, is the longest Great Wall in history. In the Ming Dynasty, in order to defend against the Tartars and the Wabashis, the construction of the Great Wall never stopped, from the Hongwu to the Wanli, during which after 20 large-scale construction, built a west of the Jiayuguan Pass in Gansu Province, east of the Liaodong Hushan, a total length of 6,350 kilometers of the border wall. (But the pedometer of a Chinese man who hiked the entire length of the Great Wall in 1990 reportedly showed 6,700 kilometers.)
The Great Wall has great tourist and sightseeing value and historical and cultural significance. Now after careful development and restoration, Shanhaiguan, Juyongguan Badaling, Simatai, Mutianyu, Jiayuguan and other places have become famous tourist attractions. Stomping on the high and distant view, with the ancient Huaiyue, the ancient battlefield of the gold, iron and horse seems to be in front of us. Nowadays, the Great Wall and the Egyptian pyramids, the Colosseum in Rome, the Leaning Tower of Pisa in Italy, etc. are known as the Seven Wonders of the World, which is the monument of the ancient culture of the Chinese nation and the crystallization of wisdom, symbolizing the bloodline of the Chinese nation and the spirit of the nation.
