The Great Wall of Qin was built in the 3rd century BC and has a long history, with a history of more than 2,300 years. If you go back to the Great Wall of the Western weekend and the Spring and Autumn Period and the Warring States Period, the Great Wall of China is at least 2,700 years old. Even the Great Wall built in the Ming Dynasty is more than 600 years old.
Such an ancient great building is still well preserved to this day, which is very rare, precious and rare in the world.
2. The length is amazing
From the Spring and Autumn Period to the Ming Dynasty, the Great Wall was maintained and built to varying degrees. The Great Wall is located in the Yellow River, the Yangtze River basin of 16 provinces, municipalities and autonomous regions. It has east-west and north-south directions, with a total length of 108,000 miles (54,000 km).
Among them, thousands of miles away, there are the Great Wall of Qin, the Great Wall of Han and the Great Wall of Ming.
3. The project is huge
According to the rough calculations of scientists, if a wall of 1 meter wide and 5 meters high is built from the earth, bricks and stones of the Great Wall of the Ming Dynasty, it can go around the earth; If it is used for laying meters of thickness and width of 5 meters. This path can circle the earth up to three times.
Length. Due to the age, most of the Great Wall of the early dynasties are incomplete, and the Great Wall built in the Ming Dynasty is relatively intact, so people generally refer to the Great Wall of the Ming Dynasty, and the length of the Great Wall is the length of the Great Wall of the Ming Dynasty.
On April 18, 2009, the State Administration of Cultural Heritage and the State Bureau of Surveying and Mapping jointly announced that the Great Wall of the Ming Dynasty stretched from Hushan in Liaoning Province in the east to Jiayuguan in Gansu Province in the west, and traveled from east to west through 156 counties in ten provinces (autonomous regions and municipalities directly under the central government) of Liaoning, Hebei, Tianjin, Beijing, Shanxi, Inner Mongolia, Shaanxi, Ningxia, Gansu and Qinghai, with a total length of kilometers. After thousands of kilometers of trenches, the natural natural danger is kilometers.

Anonymous users2024-02-05The Great Wall of China is the greatest construction project in the history of human civilization, it was built more than 2,000 years ago in the Spring and Autumn Period and the Warring States Period, and was built on a large scale in the Han and Ming dynasties. Its engineering is vast and majestic, and it can be called a world miracle.
Located in northern China, the Great Wall stretches from Shanhaiguan in the east to Jiayuguan in the west, with a total length of about 6,700 kilometers.
The construction of the Great Wall lasted for more than 2,000 years, according to historical records, from the seventh century BC when the Chu State built the "Fang City", to the Ming Dynasty (1368-1644), a total of more than 20 vassal states and feudal dynasties built the Great Wall, of which the length of the Changbianxiang City in the Qin, Han and Ming dynasties exceeded 5,000 kilometers.
The main project of the Great Wall is the tall city wall that stretches for thousands of miles, most of them are built in the highest part of the mountain range, on the city wall of ten thousand miles, there are hundreds of Xiongguan, passes, thousands of enemy platforms, beacon towers, the Great Wall of Badaling in Beijing is particularly solid, and it is also the most well preserved. In addition to the Badaling Great Wall in Beijing, there are also Jinshanling Great Wall, Mutianyu Great Wall, Simatai Great Wall, Gubeikou Great Wall, Tianjin Huangyaguan Great Wall, Hebei Shanhaiguan, Gansu Jiayuguan and so on.
The Great Wall of China is the world's longest construction, the largest amount of national military defense project in the era of cold weapon war, according to historical records, since the Warring States period, more than 20 vassal states and feudal dynasties have built the Great Wall. The first state of Chu began to build the Great Wall to defend against northern nomads or enemy countries, and later, Qi, Yan, Wei, Zhao, Qin and other countries also began to build their own Great Wall for the same purpose.
Only the remains of the Great Wall of Qin remain. Qin Shi Huang mobilized 300,000 people to build the Great Wall, creating a miracle in the history of human architecture. The construction of the Great Wall objectively played a positive role in preventing the southern invasion of the Xiongnu and protecting the economic and cultural development of the Central Plains.
Mr. Sun Yat-sen's wheel Qicha once commented: "Although the first emperor has no way, the Great Wall has contributed to future generations, and it is actually Yu to control the water."
The Han Dynasty continued to build the Great Wall. From Emperor Wen to Emperor Xuan, it has been built into a city from Dawan Ershi in the west to the north bank of the Heilongjiang River in the east, with a total length of nearly 10,000 kilometers, and half of the ancient Silk Road is along this Great Wall, which is the longest Great Wall in history. In the Ming Dynasty, in order to defend against the invasion of the Tatars and the Tile, the construction of the Great Wall has never been interrupted, from Hongwu to Wanli, during which after 20 large-scale constructions, a side wall of 6,350 kilometers was built from Jiayuguan in Gansu in the west to Hushan in Liaodong in the east.
The Great Wall has high tourist value and historical and cultural significance.
During the Spring and Autumn Period and the Warring States Period from the fifth to the seventh century BC, the princes of the Central Plains fought for hegemony and wars were frequent. In order to defend the Central Plains from being harassed by the powerful nomadic tribes of the northern grasslands, the Yan, Zhao, Qin and other countries in the north built high walls in the key places. Qin Shi Huang unified China and connected the Great Wall of the countries into a line, thus forming a military barrier from Lintao in Gansu Province in the west to Yanjin Wanli in Liaodong in the east, creating a world-famous ancient engineering miracle. >>>More
In ancient times, humans have used fragrances to change the smell of the human body, and the use of fragrances and the origin of patented perfumes as the upper class of rulers have been forgotten with the passage of time. If the widespread use of fragrance technology under the influence of the Orientals opened the first page in the history of perfumery, then it was the distillation process invented by the Arabs that made a new contribution to the development of perfumery. Next, the Crusades led to the discovery of essential oils by the French, and thus established the supremacy of France in the perfume kingdom today. >>>More
In the third century B.C., Maneto divided the history of Egypt from Menes to the conquest of Alexander in Macedon into thirty (or thirty-one) dynasties, on the basis of which scholars now divide the history of ancient Egypt into the following periods: 1 Predynastic period (period of gold and stone, c. 4500-3100 B.C.) 2 Early dynastic period (1-2 dynasties, c. 3100-2680 B.C.) 3 Old Kingdom period (3-6 dynasties, c. 2686-2181 B.C.) 4 First Intermediate Period (7th-10th Dynasty, c. 2181-2040 B.C.) 5 Middle Kingdom Period (11th-12th Dynasty, c. 2040-1786 B.C.) 6 Second Intermediate Period (13th-17th Dynasty, c. 1786-1567 B.C.) 7 New Kingdom Period (18th-20th Dynasty, c. 1567-1085 B.C.) 8 Later Dynastic Period (21th-31st Dynasty, c. 1085-332 B.C.) 9 Macedonian Greeks and Romans (332 BC – 642 AD) The 1st to 4th periods were the period of the formation of slave states and the emergence of unified dynasties, the 5th to 7th periods were the period of the re-establishment of the unified kingdom and the empire, and the 8th to 9th periods were the period of the decline of the slave states of Egypt and the fall under foreign rule.

The exact date of China's history is the first year of the Western Zhou Dynasty, that is, 841 BC, 2847 years ago. However, it cannot be said that the history of our country is less than 3,000 years, or that the history before this is unreliable. Because "there is an exact chronology", "there is a written test", "entering the era of civilization (i.e., the history of civilization)" and "the history of the activities of our people (i.e., the history of the people in general)" are completely different concepts >>>More
