Great Wall resources are mainly distributed in Hebei, Beijing, Tianjin, Shanxi, Shaanxi, Gansu, Inner Mongolia, Heilongjiang, Jilin, Liaoning, Shandong, Henan, Qinghai, Ningxia, Xinjiang and other provinces, autonomous regions and municipalities. According to the results of the national Great Wall resources survey conducted by cultural relics and surveying and mapping departments, the total length of the Great Wall in Ming Dynasty was 885 1.8km, and that in Qin and Han Dynasties and its early period was more than 1 1,000km, and the total length was more than 2 1 1,000km.
196 1 On March 4th, the Great Wall was announced by the State Council as the first batch of national key cultural relics protection units. 1987 65438+February, the Great Wall was listed as a world cultural heritage.
History:
The Great Wall is an ancient defense project with the longest construction time and the largest engineering quantity in China and even in the world. Since the Western Zhou Dynasty, it has been built continuously for more than 2,000 years, distributed in the vast land in northern and central China, with a total length of more than 50,000 kilometers.
Since Qin Shihuang, almost all dynasties that ruled the Central Plains have built the Great Wall. There are more than ten dynasties such as Han, Jin, Northern Wei, Eastern Wei, Western Wei, Northern Qi, Northern Zhou, Sui, Tang, Song, Liao, Jin, Yuan, Ming and Qing, all of which have built the Great Wall of different scales. Judging from the ruling nationalities who built the Great Wall, besides the Han nationality, many dynasties in which ethnic minorities ruled China also built the Great Wall, more than those ruled by the Han nationality. During the Kangxi period of the Qing Dynasty, although the construction of the Great Wall was stopped on a large scale, it was later built in some places. It can be said that from the Spring and Autumn Period and the Warring States Period to the Qing Dynasty, the construction of the Great Wall has never stopped for more than two thousand years. According to historical documents, more than 20 vassal states and feudal dynasties built the Great Wall. If you add up the Great Wall built in each era, it is more than 10 Wan Li, and the length of the Great Wall built in Qin, Han and Ming dynasties is more than 1 Wan Li.
The history of building the Great Wall can be traced back to the Western Zhou Dynasty. In order to resist the attack of nomadic people in the north, the Zhou Dynasty built a series of castles "Fierce Cities" for defense. During the Spring and Autumn Period and the Warring States Period, in order to compete for hegemony and defend each other, countries built the Great Wall on their borders according to their respective defense needs. The earliest building was the "Chu Fangcheng" in the 7th century BC. Later, the vassal states of Qi, Han, Wei, Zhao, Yan, Qin and Zhongshan all built the "Great Wall of Mutual Defense" for self-defense. Among them, Qin, Zhao and Yan are adjacent to Xiongnu, a powerful nomadic people in the north. While they were building the Great Wall to prevent feudalism, they also built the Great Wall in the north to resist Hu. Since then, almost all monarchs have been reinforced and built. At this time, the Great Wall is characterized by different directions in the east, south, west and north, and its length is short, ranging from several hundred kilometers to 1000-2000 kilometers. In order to distinguish it from the Great Wall of Wan Li built by Qin Shihuang, historians call it the Great Wall of Pre-Qin Dynasty.

Information story and historical brief introduction of the Great Wall
1, Qin Changcheng (the Great Wall built by Qin Shihuang) In the thirty-third year of Qin Shihuang (2 14 BC), he sent general Meng Tian to drive the Xiongnu in the north, and built the Great Wall in Lintao, Gansu (now Wang Er, Sanshidun Village, Lintao xin tian zhen) and Liaodong in the east to stop the Xiongnu from going south, which was called Qin Changcheng in history. In Guyuan area, it was actually built on the basis of the Great Wall of Qin, Zhao and Yan during the Warring States Period. East and west across Xiji, Guyuan and Pengyang counties. On Sedang Mountain, 7 kilometers north of Guyang County, a winding dragon lies quietly among the mountains. Looking from a distance, it is magnificent and extraordinary. This is one of eight wonders of the world, one of the seven wonders of the world in the Middle Ages, and Qin Changcheng, which is listed as a national key cultural relic protection unit. 2. The Ming Great Wall The Ming Great Wall is a military defense project built in the northern part of the Ming Dynasty, also known as the side wall, which is different from the Great Wall of Wan Li built by Qin Shihuang. National Cultural Heritage Administration and the State Bureau of Surveying and Mapping released the data of the Ming Great Wall for the first time on April/0/8, 2009: it starts from Hushan, Liaoning Province on the Yalu River in the east, reaches Jiayuguan, Gansu Province at the foot of Qilian Mountain in the west, and passes through Liaoning, Hebei, Tianjin, Beijing, Shanxi, Inner Mongolia, Shaanxi, Ningxia, Gansu and Qinghai 150 provinces (autonomous regions and municipalities directly under the Central Government) from east to west. Among them, the length of artificial wall is 6259.6 kilometers; The trench is 359.7 kilometers long; The length of natural insurance is 2232.4 kilometers. The wall of the eastern danger zone is made of stone and blue bricks, which is very strong. From Yalu River in the east to Jiayuguan in the west, it winds for more than 6,000 kilometers, which is magnificent and can be called a miracle of the world. 3. The legend of Meng Jiangnu crying on the Great Wall is widely circulated among the people. Her husband Wan Xiliang was recruited by Wang Wei to build the Great Wall. He died of fatigue and hunger and was buried under the Great Wall. Meng Jiangnv found her husband in Chishan section of Weihui, and cried to the Great Wall, which moved the world. The Great Wall collapsed, revealing her husband's bones.

The history of the great wall
Development originated in the Spring and Autumn Period and the Warring States Period. In order to resist the invasion of other countries, the princes of Zhao Yan. After the beacon tower was completed, it was connected with the city wall, forming the earliest Great Wall. Since then, almost all kings have strengthened and built the Great Wall. It is also called "Wan Li Great Wall" because it is tens of thousands of Li Long. According to records, Qin Shihuang used nearly one million laborers to build the Great Wall, accounting for one twentieth of the country's total population at that time. At that time, there was no machinery, all the labor was done by manpower, and the working environment was very difficult, with mountains and cliffs. The Great Wall was built in the Spring and Autumn Period and the Warring States Period with a history of more than 2,000 years. Today's Wan Li Great Wall refers to the Great Wall built in the Ming Dynasty. People who have been to the Great Wall at all times and all over the world are amazed at its majestic momentum, grand scale, arduous engineering and preventive significance. It combines the wisdom, will, perseverance and endurance of the ancients. Therefore, the Great Wall is a rare treasure and an extraordinary cultural relic. It symbolizes the great will and strength of the Chinese nation and is the pride of the Chinese nation and the whole world. In the Ming Dynasty, in addition to the "outer" Great Wall, the "inner" Great Wall and the "inner three passes" Great Wall were also built. The "interior wall" starts from Pianguan at the junction of Inner Mongolia and Shanxi in the west, enters Hebei at Yanmenguan and Xing Ping in the east, then goes to the northeast, passes through Yuanyuan, Fangshan and Changping counties, reaches Juyongguan, and then reaches Huairou No.4 Pass from north to east, and is connected with the "Outer" Great Wall, with Zijingguan as the center, generally showing a north-south trend. The "Neisanguan" Great Wall is parallel to the "Inner" Great Wall in many places. In some places, the two cities are only tens of miles apart. In addition, a large number of "heavy cities" have been built. There are as many as 24 "heavy cities" around Yanmenguan. According to historical documents, more than 20 vassal states and feudal dynasties built the Great Wall. If you add up the Great Wall built in past dynasties, it is about 10 Wan Li. The length of the Great Wall in Qin, Han and Ming Dynasties exceeded 1 Wan Li. China, Xinjiang, Gansu, Ningxia, Shaanxi, Inner Mongolia, Shanxi, Hebei, Beijing, Tianjin, Liaoning, Jilin, Heilongjiang, Henan, Shandong, Hubei, Hunan and other provinces, municipalities and autonomous regions all have the remains of the ancient Great Wall and beacon towers. Folding the Great Wall in Wan Li Scenery of the Great Wall in Wan Li during the Warring States Period The Great Wall in northern China began in the Warring States Period, with Qin, Zhao and Yan. [2] Why did Qin build the Great Wall in the north, starting from the situation in the Warring States period. During the Warring States Period, the middle and lower reaches of the Yellow River and the Yangtze River in China changed from a slave society to a feudal society, and the exchanges and integration with the cultures of Qin, Chu and Wu and Yue became increasingly strong. After the seven countries of Wei, Zhao, Han, Chu, Qi, Qin and Yan, which were carrying out feudal reforms at that time, became powerful, they waged a war of annexation and sought to unify the middle and lower reaches of the Yellow River and the Yangtze River by force. At this time, the ethnic minorities in the grasslands of northern Shaanxi, northern Shanxi, northern Hebei and Inner Mongolia, mainly Huns, gradually became stronger and plundered the northern borders of Qin, Zhao and Yan. There are Yiqu and Xiongnu in northern Qin; There are loufan in the northwest of Zhao, and Huan and Xiongnu in the north. There is East Lake in the northern boundary of Yan State. Since the mid-Warring States period, they have been plundering Qin, Zhao and Yan in the northern region. Because they are good at riding and shooting, are good at fighting, take sudden attacks, come and go freely, haunt, and show strong combat effectiveness. In the middle of the Warring States period, the fighting troops of Qin, Zhao and Yan were mainly infantry and chariots, wearing big sleeves that took off their coats and moving slowly for 30 to 50 miles a day. Nature can't stop the attack and plunder of Xiongnu and Donghu people. This not only seriously threatened the lives and property of the people in the northern part of the three countries, but also seriously damaged their production and greatly affected the cause of reunification of the three countries. In response to this passive situation, the three countries successively carried out military reforms and built the Great Wall in the north. Starting from Shang Yang, the State of Qin began to reform and promote Qiang Bing to become a rich country. The army gradually changed into infantry and cavalry, and was rewarded and promoted with military merit, so the combat effectiveness of the army increased and it was invincible. In six years (the first 332 years) and ten years, King Huiwen defeated Wei and seized Weixi County (now Luohe Valley in Shaanxi Province) and Shangjun County (now northeast Shaanxi Province). In order to prevent the Huns from plundering the south, Zhao Haoqi ordered the Great Wall to be built on the northern border of Longxi, Beidi and Shang Jun, and sent troops to station it. Zhao Wuling began to reform the military system in the nineteenth year (the first 307 years) and was riding and shooting. Since then, the troops have become more powerful. In twenty years, King Wuling traveled west to Hu Lin, and when he arrived in Yuzhong, King Hulin dismounted and went home. In the twenty-sixth year (the first three hundred years), Zhongshan was broken, and the prosperous place reached Yan and Dai in the north (now northwest of Shanxi), and then extended to Yunzhong and Jiuyuan in the northwest (now from Helinger County to Wujiahe in Inner Mongolia). So he ordered the construction of the Great Wall, merged with Yinshan Mountain (now Daqing Mountain and Wulate Mountain in Inner Mongolia), and went west to reach the Dahe River (now Wujiahe River in Inner Mongolia). At the same time, Daijun County, Yanmen County and Yunzhong County were set up to prevent the Huns from plundering south. In order to specialize in Northwest China, the following year, he gave way to his son, Wang Huiwen He, who was named the main father. In the second year of King Huiwen (297 BC), his father went to Xihe (the Yellow River between Shanxi and Inner Mongolia), and the ruined building angered the king and sent troops. Yan State is the weakest of the Seven Heroes in the Warring States Period, bordering Qiangqi and the newly established Zhao State in the south and East Lake in the north. It was not until he ascended the throne (the first 3 1 1) that Yan became strong, recruited talents and carried out reforms. At that time, Donghu was powerful and often plundered the northern part of Yan. In order to maintain the peace in the north, the Yan army was forced to make peace with King Donghu and held the general hostage. Zhao Shi was born in East Lake. He is clever and brave, and King Donghu trusts him very much. Therefore, he is free to move, and he can understand the dangers and obstacles, protection and laws of military activities in the south of East Lake. After returning home, he led an army to attack East Lake, which was broken, but it was thousands of miles away. And "crossing Liaodong to attack Korea" was extended to Tanshui (now Qingchuan River in North Korea). So, "Yan also built the Great Wall to make Yang (now kangbao county, Hebei, Taibus Banner, Inner Mongolia) go to Xiangping; Put it in Shanggu, Yuyang, Youbeiping, Liaoxi and Liaodong counties to refuse Hu. " To sum up, the reason why Qin, Zhao and Yan built the Great Wall in the north during the Warring States Period was to prevent the Xiongnu, Donghu and other ethnic groups from looting and killing. Wan Li Great Wall-South Great Wall Wan Li Great Wall-South Changcheng South Great Wall 1. The Great Wall of Chu, represented by Chu, Qi, Wei, Han and Zhongshan countries, gradually faded out of our memory with the passage of time. 30 years ago, the Great Wall of Chu was built in Chu Huaiwang, and it was called "Fangcheng" at that time. Its location should be Biyang, Henan, to Yexian in the north, and to Zhushan County, Hubei Province through the northeast of Neixiang, in order to defend against the attacks of neighboring countries. 2. The Great Wall of Qi is continuously extended by connecting mountains with dikes. In the south of Qi State, it starts from the northeast of Pingyin County, Shandong Province, and reaches the sea in Nandazhu, jiaozhou city. There are two main structures: earth and stone. Zhongshan Great Wall Zhongshan Great Wall was built to resist the invasion of Zhao and Jin in southwest China. It was built in Zhao Chenghou for six years (369 BC). Its location is in the area where Hebei and Shanxi meet today. There are two Great Walls in Wei: one is the Great Wall against Qin and Rong in the northwest (Hexi Great Wall), and the other is the South Great Wall (Henan Great Wall). When Wei Huiwang was in power, it started from Xiangyuan Cave at the northern foot of Huashan Mountain in hua county, Shaanxi Province in the west, and went to Guyang, Inner Mongolia in the south, expanding the Luoshui levee in the west and building the Great Wall in Hexi. In his later years, Wei Huiwang built the South Great Wall to protect the girders of the capital, passing through Yuanyang County, Henan Province, and turning to Xinmi City in the southeast and west. The Great Wall of Korea was first built by Zheng, then destroyed by Han, and continues to be built and used. Folding the scenery of Wan Li Great Wall in the Han Dynasty and Wan Li Great Wall in the early Han Dynasty, Xiongnu crossed the Great Wall built by Qin and Meng Tian in the Central Plains War and once again bordered the Great Wall of Qin, Zhao and Yan in the Warring States. Due to the disrepair of the Great Wall and the scarcity of defenders in the north, the powerful Xiongnu continued to plunder the Great Wall and went deep into Daigu, Taiyuan, Xihe, Shang Jun and Beidi counties. Emperor Gaozu, Hui Di, Wendi and Jingdi were forced to adopt a pro-Xiongnu policy. Marry a princess to be E Shi (queen) for Khan and give him a lot of wealth. However, even this dilapidated Great Wall has played a role in military defense to a certain extent. If it weren't for the Xiongnu army, it would be impossible to enter the Great Wall and plunder. Secondly, if the defenders are effective, even with the Xiongnu army, they can't enter the Great Wall. Like Li Guang, Cheng Wu is also a famous Great Wall Guardian. He was very strict in running the army and was always on guard against the Huns' surprise attack, which also showed that the Great Wall of the Warring States period played a certain role. Later, Wei Qing, Huo Qubing, GongSunHe, Gong and others attacked the Huns, all of which were based on Zhao and Qin Changcheng. This shows that until the early Western Han Dynasty, the Great Wall of Qin, Zhao and Yan in the Warring States period was still playing a military defense role, although its defense ability was much worse than that in the Warring States period. It was not until Emperor Wu of the Han Dynasty drove the Huns to Mobei, restored the Qin Changcheng built by Meng Tian and built the Outer Great Wall that the Great Wall of Qin, Zhao and Yan in the Warring States was abandoned and the military defense function ended. The Great Wall restored in Ming Dynasty was supervised by Zhang's subordinate Qi Jiguang, and the Great Wall in Qin Dynasty was in ruins. However, the Great Wall built in Qi Jiguang was also built by Nanshanling Great Wall and Badaling Great Wall (to implement Zhang's whipping method)

A brief introduction to the history of the Great Wall, the simpler the better.
The Great Wall is an ancient military defense project in China. It is a tall, solid and continuous long wall, which is used to limit the enemy's riding. The Great Wall is not a simple isolated wall, but a defense system with the wall as the main body and a large number of cities, obstacles, pavilions and landmarks. Great Wall resources are mainly distributed in Hebei, Beijing, Tianjin, Shanxi, Shaanxi, Gansu, Inner Mongolia, Heilongjiang, Jilin, Liaoning, Shandong, Henan, Qinghai, Ningxia, Xinjiang and other provinces, autonomous regions and municipalities. Shaanxi Province is the province with the richest resources of the Great Wall in China, with a total length of 1838 km. According to the results of the national Great Wall resources survey conducted by cultural relics and surveying and mapping departments, the total length of the Great Wall in Ming Dynasty was 885 1.8km, and it was more than 1 1,000 km in Qin and Han Dynasties and its early period, and the total length was more than 2 1 1,000 km. Symbolic Significance of Expansive Materials The Great Wall of Wan Li has become a symbol of the unity of the Chinese nation since its completion. For more than two thousand years, no one can split the Great Wall of Wan Li cognitively, so it is impossible to split the Chinese nation. For China people, the Great Wall is a symbol of will, courage and strength, and symbolizes the great will and strength of the Chinese nation. March of the Volunteers's long-term singing has sublimated the Great Wall into an industrious, intelligent, indomitable and indestructible national spirit and will in people's minds, and enhanced the pride, self-confidence and patriotic enthusiasm of the Chinese nation.

There are historical materials about the Great Wall.
The Great Wall is an ancient defense project with the longest construction time and the largest engineering quantity in China and even in the world. Since the Western Zhou Dynasty, it has been built continuously for more than 2,000 years, distributed in the vast land in northern and central China, with a total length of more than 50,000 kilometers. Since Qin Shihuang, almost all dynasties that ruled the Central Plains have built the Great Wall. There are more than ten dynasties such as Han, Jin, Northern Wei, Eastern Wei, Western Wei, Northern Qi, Northern Zhou, Sui, Tang, Song, Liao, Jin, Yuan, Ming and Qing, all of which have built the Great Wall of different scales. The Great Wall is an ancient military defense project in China. It is a tall, solid and continuous long wall, which is used to limit the enemy's riding. The Great Wall is not a simple isolated wall, but a defense system with the wall as the main body and a large number of cities, obstacles, pavilions and landmarks. Representative section of the Great Wall: 1. Shanhaiguan Shanhaiguan is called "the first pass in the world", which is located at 15km northeast of Qinhuangdao City, Hebei Province, where the Great Wall of Wan Li enters the sea. The total length is 26 kilometers, including: Laolongtou Great Wall, Guancheng Great Wall in the south wing, Jiao Shan Great Wall in the north wing, Sandaoguan Great Wall and Jiumenkou Great Wall. Laolongtou Great Wall is the end part of the Great Wall entering the sea. Shanhaiguan was the product of the garrison system established in Ming dynasty, and the "reclamation system" and reform policy of Ming dynasty played an important role in the consolidation and development of Shanhaiguan. 2. Zhenbeitai Town Beitai is located in Yulin City, Shaanxi Province, a famous historical and cultural city, about 3 kilometers away from the urban area. Built in the thirty-fifth year of Wanli in the Ming Dynasty (1607), it is the most magnificent building in the Great Wall of Wan Li. It is also the most magnificent military fortress and observation post on the Great Wall of Wan Li. Known as "one of the three wonders" of the Great Wall of China (Shanhaiguan in the east, Zhenbeitai in the middle and Jiayuguan in the west), it is "the best in the world". According to the danger, it is square, with four floors, more than 30 meters high and an area of 5056 square meters. 3. Jiayuguan Great Wall Jiayuguan Great Wall is located in the southwest corner of Jiayuguan City, Gansu Province. It was named after it was built at the foot of Jiayu Mountain. It is the starting point of the western end of the Ming Great Wall. It was built in the fifth year of Hongwu in Ming Dynasty (1372). It is the most well-preserved Chengguan along the Great Wall in the Ming Dynasty, the first pass in Hexi and an important stop on the Silk Road. Chengguan is a complete defense system composed of inner city, outer city and moat. Rammed by loess and covered with city bricks, it is solid and majestic. The Guancheng plane is trapezoidal, covering an area of more than 33,500 square meters, with a total length of 733 meters and a height of 1 1.7 meters. Baidu encyclopedia-great wall

Introduction and information of the Great Wall
The Great Wall The Great Wall is a miracle created by working people in ancient China. Because it is longer than Wan Li, it is also called "Wan Li Great Wall". Building the Great Wall has been a big project since the Qin Dynasty. According to records, Qin Shihuang used nearly one million laborers to build the Great Wall, accounting for 1/20 of the country's total population at that time. At that time, there was no machinery, and all labor depended on manpower. The working environment was steep mountains and deep cliffs. As you can imagine, it is impossible to complete this great and arduous project without a large number of people working hard, which contains the sweat and wisdom of the ancient working people. In the long history of China, many feudal dynasties built the Great Wall many times in order to consolidate their rule. In ancient China, thousands of working people in Qian Qian contributed wisdom and blood to it, making it a wonder of the world. Both the dragon-shaped city wall and the throat artery reflected the war thought of building a city at that time, and also marked the high achievement of architectural technology at that time.

Edit this section | Go back to the top to summarize that the Great Wall is a miracle created by working people in ancient China, and it is also called because its length exceeds that of Wan Li. Building the Great Wall has been a big project since the Qin Dynasty. According to records, Qin Shihuang used nearly one million laborers to build the Great Wall, accounting for 1/20 of the total population at that time. At that time, there was no machinery, and all projects depended on manpower. The working environment was steep mountains and deep cliffs. As you can imagine, this great and arduous project could not be completed without a large number of people working hard. During the Spring and Autumn Period and the Warring States Period, in order to prevent the invasion of other countries, the vassal States built beacon towers one after another and connected them with city walls, forming the earliest Great Wall. Later, most of the kings of the past dynasties strengthened and repaired. The Great Wall starts from Shanhaiguan in the east and ends at Jiayuguan in the west. The total length of the Great Wall in Ming Dynasty was 885 1.8km, of which the artificial Great Wall was 6,259.6km and the length of trenches and natural disasters was 2,592.2km ... "Because of the terrain, traffic was blocked by danger" was an important experience in the construction of the Great Wall, which was affirmed by Qin Shihuang and recorded by Sima Qian in Historical Records. After that, every dynasty built the Great Wall according to this principle. All the passes in Guancheng are built between two high mountains and canyons, or at the bend of a river, or where they will pass through the plain, which can not only control the danger, but also save manpower and material resources, and achieve the effect of "one person guards it, and ten thousand people can't force it". Building castles or beacon towers is also an option in Four Essentials. As for building city walls, we should make full use of the terrain. For example, Juyongguan, Badaling and other Great Walls are all built along the back of the mountain. Some sections are very steep from the outside of the city wall, but very gentle from the inside, thus achieving the effect of "easy to defend but difficult to attack". In Liaoning Province, the Great Wall of Liaodong Town in Ming Dynasty was called the Mountain Dangerous Wall and the Split Gable, which was made by slightly splitting the steep cliff. Some places completely use cliffs, rivers and lakes as natural barriers, which can be said to be wonderful. As a great project, the Great Wall has become a precious heritage of the Chinese nation. On June 25th, 20001year, the Great Wall, as an ancient building from the Spring and Autumn Period to the Ming Dynasty, was approved by the State Council to be included in the fifth batch of national key cultural relics protection units. 【 Name of Special Pass 】 There are many passes on the Great Wall of Wan Li. These places are mostly named after "Guan" and "Kou". In Zhangjiakou Great Wall, it is named after the "gate" and is called "Dajingmen". In the Ming Dynasty, in addition to the "outer" Great Wall, the "inner" Great Wall and the "inner three passes" Great Wall were also built. The "Neiguan" Great Wall, based on the Northern Qi Dynasty, starts from Pianguan at the junction of Inner Mongolia and Shanxi in the west, Yanmenguan and Pingxingguan in the east, enters Hebei, then turns to the northeast, passes through Yuanyuan, Fangshan and Changping counties, reaches Juyongguan directly, and then reaches Huairou Siguan from north to east, and is connected with the "Outer" Great Wall, with Zijingguan as the center, showing a general north-south trend. The "Neisanguan" Great Wall is parallel to the "Inner" Great Wall in many places. In some places, the two cities are only tens of miles apart. In addition, a large number of "heavy cities" have been built. There are 24 "heavy cities" in Yanmenguan area! The Great Wall lies in the north of China. It starts from Yalu River in the east and reaches Jiayuguan in the inland area of Gansu in the west. It spans seven provinces, municipalities and autonomous regions, including Hebei, Beijing, Inner Mongolia, Shanxi, Shaanxi, Ningxia and Gansu, with a total length of about 6,700 kilometers, or about13,300 miles, and is known as the "Great Wall of Wan Li" in the world. It criss-crosses the east, west, north and south, and stretches on the vast land of our great motherland. It is like a dragon, crossing towering mountains, vast grasslands, vast deserts and heading for the vast sea. According to historical documents, more than 20 vassal states and feudal dynasties built the Great Wall. If you add up the Great Wall built in past dynasties, it is about 10 Wan Li. The length of the Great Wall in Qin, Han and Ming Dynasties exceeded 1 Wan Li. At present, Xinjiang, Gansu, Ningxia, Shaanxi, Inner Mongolia, Shanxi, Hebei, Beijing, Tianjin, Liaoning, Jilin, Heilongjiang, Henan, Shandong, Hubei, Hunan and other provinces, cities and autonomous regions have the remains of the ancient Great Wall and beacon towers. Among them, the Great Wall of Inner Mongolia Autonomous Region alone reaches 3 Vandory. Edit this paragraph | Back to the top starting point According to historical documents, there are three dynasties in which the Great Wall is more than 5,000 kilometers: First, the Great Wall of Wan Li was built from Qin Shihuang in the west and Liaodong in the east; Second, the Great Wall and beacon towers built in the Han Dynasty, with a total length of more than 10000 kilometers, from Xinjiang in the west to Liaodong in the east; 3. Jiayuguan in the west and the Great Wall along the Yalu River in the east, built in the Ming Dynasty, with a total length of 8851.8km (revised in 2009). If you add up the Great Wall built in different periods, it will be more than 50,000 kilometers. These Great Wall sites are distributed in Xinjiang, Gansu, Ningxia, Shaanxi, Shanxi, Inner Mongolia, Hebei, Beijing, Tianjin, Liaoning, Heilongjiang, Henan, Hubei, Hunan, Shandong and other provinces, cities and autonomous regions/kloc-0. Among them, only Inner Mongolia Autonomous Region has 1.5 million kilometers of sites. Followed by the Great Wall of Gansu. Because of its long history, most of the early Great Wall was incomplete, and now the Great Wall built in Ming Dynasty is relatively complete. So when people talk about the Great Wall, they mainly refer to the Ming Great Wall. The length of the Great Wall also indicates the length of the Great Wall, from Jiayuguan in the west to Yalu River in the east. The following is a couplet "Praise of the Great Wall" written by China Great Wall expert Luo: from the Spring and Autumn Period to Qin and Han Dynasties, from Liao and Jin Dynasties to Yuan and Ming Dynasties, up and down for two thousand years. Countless generals, officials and soldiers, Li Shu worked hard to move mountains and rivers to build this great project. Strong perseverance, wisdom and diligence have left a towering monument for China. Across the mountains, across the wasteland, across the vast sea, across the cliff, thousands of miles. Looking around, the continuous long queues and peaks, Xiongguan is like a jade belt inlaid with pearls, dotted with beautiful scenery. Ups and downs, flying and hovering, overlooking in space, have added magnificent wonders to this world. Edit this paragraph | Back to the top building structure and building materials The Great Wall has been built many times in order to consolidate its rule in China's long history; In ancient China, thousands of working people in Qian Qian contributed wisdom and blood to it, making it a wonder of the world. Both the dragon-shaped city wall and the throat artery reflected the war thought of building a city at that time, and also marked the high achievement of architectural technology at that time. For example, during the Ming Dynasty, with the high development of feudal economy, the construction industry also embodied a huge production process and a relatively scientific brick and tile firing workshop. Therefore, the output of brick products has greatly increased, and bricks are no longer precious building materials, so the inner and outer eaves of many places in the Great Wall of Ming Dynasty are built with giant bricks. Under the conditions of manual construction and manual handling of building materials at that time, it was not only convenient to build the city wall with bricks with small weight and the same size, but also improved the construction efficiency and building level. Secondly, the gates of many passes are long-span arches made of blue bricks. Some of these blue bricks have been severely weathered, but the whole gate is still magnificent, showing the superb skills of building arches at that time. Judging from the architectural decoration of the Guanta Tower, many stone carvings and brick carvings are extremely complicated and elaborate, reflecting the artistic talent of craftsmen at that time. Edit this paragraph | Back to the Top Military Significance The Great Wall is not only the defensive front of the farming people, but also the forward base for launching a counterattack against the nomadic people. Behind the Great Wall, mobile troops are equipped in depth to deal with the war. The Great Wall is not the forefront of defense, but the starting line and traffic line of attack. The observation post deployed in front of the Great Wall goes very far, and the front line is north of the Great Wall 1000 km. In ancient times, nomadic cavalry had excellent maneuverability and strong attack power, but they could do nothing about the wall defense system, so they built the Great Wall.
