The Great Wall is the world's longest artificial construction in China. Unesco's Science, Education and Culture Organization has recognized China's Great Wall as a World Cultural Heritage in 1987.

The Great Wall means that the city is long-lasting , is the famous wall of China built with earth and stone from the 5th century BC. The first city wall was built to protect the Chinese from the attacks of the Hungarians and the Mongols, the Turks, and other nomadic tribes from the lands of Mongolia and Manchu. Chau. Some parts of the walls were built in the 5th century, but the most famous is the rampart wall built from 220 BC to 200 BC under the Qin Shihuang Dynasty , the first emperor of China. However, the current city school was built mainly during the Ming Dynasty, the old walls are only left with few relics.

According to a preliminary study published in 2009, the length of the school is about 8,850km. But according to new data, Van Ly Truong Thanh is 21,196 km long. The average height of the school is 7m, the upper surface of the school is an average of 5-6m.

The Great Wall is built through many Chinese historical dynasties but divided into five main time periods:

The first citadel was built during the reign of Qin Shihuang, the first Emperor of the Qin Dynasty with a short lifetime. This wall was not built by the efforts of a group, but by connecting many parts of the city walls, once built in the Warring States period. At that time people connected the walls together with earth and stone. This castle is located to the north and a distance away from the present-day school. Currently only one section of this school remains. In order to join these schools together, it is estimated that there are 300,000 soldiers and countless sinners, mandarins make mistakes, the scholars refuse to obey the burning orders . they have to work hard in mountainous The forest has the same message, the winter is cold, the water is frozen, the summer is hot as the heat . There are many assumptions that up to one million workers died when completing this project.

The next school was built under the Han Dynasty and the Sui Dynasty with the same design as the Qin Dynasty. Also built from rocks and watchtowers built about a few miles apart. Wall sections constructed during this period have also been damaged by time and corrosion of wind and rain.

The Great Wall today was built during the Ming Dynasty, beginning around 1368 and ending in 1640. This castle had 25,000 watchtowers . Just like the first idea when building the wall of the Qin Shihuang Dynasty, this castle was also built with the aim of protecting the people against the invasion of the Mongols, Gentiles . The Great Wall under during the Ming Dynasty, it was calculated to start from Son Hai Quan near Vinh Dau Hai and end in Gansu province adjacent to the Gobi Desert border. The castle wall stretched over nine provinces and 100 districts, which were more than 500km long.

Militarily the city was built to divide the nation's boundaries and protect China against the invasion of other countries, but the military strategy of China did not take place around holding. Wall.

In 1644, the Manchu people crossed the castle wall by bribing an important general, Wu Tam Que . Legend has it that the Manchu army took three days to pass all the passes to enter the city. After being conquered by the Manchu people, the citadel was no longer of strategic value, most because the Manchus had extended their political control farther north, meaning the territory was expanded more than the previous Chinese dynasty.

Currently, many sections of this famous city hall have been damaged. Most of the cities are located in the tourist development provinces newly invested and restored, the rest are abandoned. There are even many sections of the city that were destroyed by the local people to get the stones to make houses. Besides, the spread of the Gobi desert also makes the foot of the wall are gradually subsided. Scientists say only about 20% of the schools are in good condition.
