What impresses me most in Beijing is the Great Wall which is one of the greatest projects in the world。 It's not only the cultural heritage， but also a symbol of China。 "It's glorious。" I think。 It looks like a big dragon running across the mountainous area。 It starts Shanhaiguan in the east to Jiayuguan in the west。 It's so long that nobody can walk from the beginning to the end。
It was firstly built in Qin Dynasty and prolonged in Ming and Qing dynasties。 It was used to protect the enemies from invading in the past， but now it has bee the place of interest which attracts so many tourists both at home and abroad。
When I was standing on the top of the Great Wall， I felt as if I were in ancient days。 I could see many laborers working very hard。 How could they finish this extremely difficult task by hand?
The Great Wall is the symbol of China。 Far see the magnificent Great Wall， like a long dragon winding between mountains， from shanhai pass to jiayu pass， there are more than thirteen thousand!
Starting from Beijing， but will a few tens of kilometers to reach the Great Wall。 Ah， the Great Wall for a long long， endless blocks， as the serpent lay to rest on the mountains。 The Great Wall is built against the many stone and ChengZhuan。 On the square brick on the top， very neat， like a broad road， WuLiuPi horses to go side by side。 Outside walls along the rows of buttress has two meters high， above the square at the mouth and the nozzle， for observation and shooting， and on the top of the wall， a ChengTai every few hundred meters - ancient war can mutual echo。 The walls of the癫痫有治疗好的可能吗 Great Wall is not a separate， but by the walls and watchtowers， GuanCheng， pier fort， city， defend the beacon tower city， town and other fortifications of plete system engineering。
If standing on the Great Wall， will naturally think of the ancient working people built the Great Wall。 Look at the stone， a piece of have two or three one thousand catties。 Less tools at that time， only by countless people’s shoulders numerous hand， step by step to carry on the steep mountain terrain。 How many working people sweat and wisdom， is the former see first， after see the Great Wall of China! Such a spirit grand project， is a great miracle!
The Great Wall of China is called the "Ten thousand Ii Great Wall" in Chinese. In fact, it' s more than 6 000 kilometres long. It winds its way from west to east, across deserts, over mountains, through valleys till at last it reaches the sea. It is one of the wonders of the world.
The Great Wall has a history of over twenty centuries. The first part of it was built during the Spring and Autumn Period. During the Warring States Period, more walls were put up to defend the borders of the different kingdoms. It was during the Qin Dynasty that the kingdom of Qin united the dif ferent parts into one empire. To keep the enemy out of his empire, Emperor Qin Shi Huang had all the walls joined up. Thus, the Great Wall came into being.
The Great Wall is wide enough at the top for five horses or ten men to walk side by side. Along the wall are watchtowers, where soldiers used to keep watch. Fires were lit on the the towers as a warning when the enemy came.
It was very difficult to build such a wall in the ancient days without any modern ma北京治疗癫痫病排名好的医院chines. All the work was done by hand. Thousands of men died and were buried under the wall they built. The Great Wall was made not only of stone and earth, but of the flesh and blood of millions of men.
Today the Great Wall has become a place of interest not only to the Chinese but to people from all over the world. Many of them have come to know the famous Chinese saying: "He who does not reach the Great Wall is not a true man."
The Great Wall building has a long history, vast engineering magnificent, is the world's rare miracle. The Great Wall is the four corners of the world, stretching in our great motherland vast land. It looks like a great dragon, surmounts lofty hills, through the vast grassland, across the vast desert, towards the vast sea. According to historical records, more than 20 states and feudal dynasty built the Great Wall, if constructs each time the Great Wall together, about 100000 miles above. The length of the Great Wall that was built by The Qin, Han, and Ming 3 Dynasty was more than 10 kilo miles. Now our country Xinjiang, Gansu, Ningxia, Shaanxi, Inner Mongolia, Shanxi, Hebei, Beijing, Tianjin, Liaoning, Jilin, Heilongjiang, Henan, Shandong, Hubei, Hunan and other province, city, autonomous regions have the ancient the Great Wall, peak fire platform remains. Of which only the Inner Mongolia Autonomous Region the Great Wall amounted to more than 3.
The Ming Dynasty in the" outside" beyond the Great Wall, also built" inside" and" three" the Great Wall the Great Wall. " Neiguan" the Great Wall in the Northern Qi Dynasty had built for the foundation, from Inner Mongolia and Shanxi at the junction of west east “Pianguan”, the Yanmenguan, flat various pass into Hebei, and then turned to the northeast, Fangshan, Changping, the source of all 癫痫日常的预防护理有哪些counties, to pass, and then by the North and East, Huairou to the four customs, and" outside" is connected to the Great Wall, Zijingguan as the center, generally in a north-south direction.

Yanmenguan area" repeated walls “to have 24 much!
The Great Wall is the working people in ancient China created the miracle. Beginning with QinShihuang, constructs the Great Wall always is a big project. According to the record, QinShihuang used the million of labors to build the Great Wall, occupy countrywide population 1 / 20! There were no machinery, in addition to earth, carrying bricks can use donkeys, goats can climb the cattle, all labor and all must rely on manpower, work environment and high mountains and lofty hills, cliff. Can imagine, no large crowds on hard work, is unable to complete the great project.
The great wall of the engineering quantity, according to rough estimates, only constructs take the Ming Dynasty as an example, if its masoy, earth is used to build a thickness of 1 meter, 5 meters high walls, circled the earth for over a week. If used for paving a 5 meters wide, 35 cm thick road, it could circle the earth three or four weeks. If all dynasties built a total of 50 thousand kilometers calculation, then this wall can rotate around the earth several weeks, this road, around the earth in thirty or forty weeks.
“Because of the terrain, with risks for plug" is the construction of the Great Wall is an important experience, in the age of QinShihuang had it down, Sima Qian writes it to" historical records".

Built a castle or Beacon Tower is selected in the" appeared to place" for building a wall, is the full use of the terrain, such as Juyongguan, the Great Wall in Badaling are built along the mountain ridge, some lots from the lateral walls look very steep, we receive" inside is smooth, easily defensible ." effect of. In the territory of Liaoning, Liaodong town of Ming Dynasty the Great Wall has called a precipitous wall, wall of the hill, is the use of vertical cliff, precipice slightly to split cutting you will become the Great Wall.
