Wonders Of The World - The Great Wall Of China

1. History of The Great Wall of China
7 wonders of the world, Seven Wonders of the Ancient World, The Great Wall Of China, what are the wonders of the world, Wonders of the world, World Heritage Sites, When tells about China. Maybe, anyone tells about Great Wall of China. This is one of seven Ancient Wonders of the Word. The Great Wall of China, one of the greatest wonders of the world, was listed as a World Heritage by UNESCO in 1987. Just like a gigantic dragon, the Great Wall winds up and down across deserts, grasslands, mountains and plateaus, stretching approximately 8,851.8 kilometers (5,500 miles) from east to west of China. With a history of more than 2000 years, some of the sections are now in ruins or have disappeared. However, it is still one of the most appealing attractions all around the world owing to its architectural grandeur and historical significance.
Chinese Name: 长城/万里长城
Length: 8,851.8 km (5,500 miles)
Construction Period: About 2,000 years from the Warring States Period (476 BC - 221 BC) to Ming Dynasty (1368-1644).
Story of the Great Wall is said to start from the Spring and Autumn Periods when seven powerful states appeared at the same time. In order to defend themselves, they all built walls and stationed troops on the borders. At that time, the total length of the wall had already reached 3,107 miles, belonging to different states.
In 221 BC, the Emperor Qin absorbed the other six states and set up the first unified kingdom in Chinese history. In order to strengthen his newly born authority and defend the Huns in the north, he ordered connecting the walls once built by the other states as well as adding some sections of his own. Thus was formed the long Qin's Great Wall which started from the east of today's Liaoning Province and ended at Lintao, Gansu Province.
In the Western Han Dynasty, the Huns became more powerful. The Han court started to build more walls on a larger scale in order to consolidate the frontier. In the west, the wall along the Hexi corridor, Yumenguan Pass, and Yangguan Pass was built. In the north, Yanmenguan Pass and Niangziguan Pass in Shanxi were set up. Many more sections of the wall extended to Yinshan Mountain and half of the ancient Silk Road was along the Han's wall.

The Northern Wei, Northern Qi and Northern Zhou Dynasties all built their own sections but on a smaller scale than the walls in the Han Dynasty. The powerful Tang Dynasty saw peace between the northern tribes and central China most of the time, so few Great Wall sections were built in this period.
The Ming Dynasty is the peak of wall building in Chinese history. The Ming suffered a lot by disturbances from minority tribes such as the Dadan, Tufan and Nuzhen. The Ming court from its first emperor to the last ceaselessly built walls in the north. The main line started from Jiuliancheng near the Yalu River in the east to the Jiayuguan Pass in the west and measured over 4,600 miles. Besides adding many more miles of its own, the Ming emperors ordered enlargement of the walls of previous dynasties into double-line or multi-line walls. For example, out of Yanmenguan Pass were added three big stone walls and 23 small stone walls. Eleven Garrisons were distributed along the main line of the wall. The countless walls, fortresses, and watch towers made the country strongly fortified. In the early Qing Dynasty, some sections of the walls were repaired and several sections were extended. This great engineering work stopped in the middle of the Qing Dynasty.
Owing to its long history, natural disasters and human activities, many sections of the Great Wall are severely damaged and disappearing. Being a world-famous engineering project and witness to the rise and fall of Chinese history, the Great Wall, needs us to take immediate action to protect it!
Like a giant dragon, the Great Wall meanders over deserts, grasslands, and mountains until finally arriving at its destination - Bohai Gulf. Zigzagging 8,851.8 km (5,500 miles) from Jiayuguan Pass in the west to Hushan Mountain in Liaoning in the east, the wall crosses over  ten provinces and cities, including Qinghai, Gansu, Ningxia, Shaanxi, Inner Mongolia, Shanxi, Hebei, Beijing Tianjin, and Liaoning. The Great Wall had witnessed many changes through several thousand years of history, from the Warring States to the Ming Dynasty.

Beijing Great Wall:                                                                                                                 
In Beijing, there are many relics of the Great Wall, most of which were built around 1540.

Gansu Great Wall:
In Gansu, numerous cultural relics of the Silk Road can be found, such as the Mogao Caves and Maijishan Grottoes. Also it played a very important role in the ancient military defense. A lot of Great Wall relics have been found in this region. The most famous one is Jiayuguan Pass in Jiayuguan City, which is the western beginning of the Ming Great Wall. Additionally, the Overhanging Great Wall is worth a visit.

Hebei Great Wall:
There are a large number of Great Wall relics in Hebei Province. Most of them were built in the Ming Dynasty. In the east of Hebei stand the Great Wall of Laolongtou, Shanhaiguan Pass, Xifengkou&Sandaoguan, Zijingguan, Jiaoshan,  Qingshankou, Malanguan, etc. In northwestern Hebei, you can see Zhangjiakou, Changyukou and Qingbiankou Great Wall. And in the southwest of Hebei, Wulonggou, Futuyu,  and Chajianling can be seen.

Inner Mongolia Great Wall
Inner Mongolia boasts the largest number of Great Wall relics. Its total length covers one third of the whole length of China Great Wall. However, a great many remains were destroyed and even some of them have died out. For instance, in the area of Juyanhai Lake, ten fire towers have disappeared.

Liaoning Great Wall
It's thought that the eastern beginning of the Great Wall is the Shanhaiguan Pass in Hebei. However, in recent years, people find that its beginning is in Liaoning Province. Most of the Great Wall in Liaoning was built in the Ming Dynasty (1368-1644). In that period, the Great Wall was divided into nine districts, called Nine Important Towns on the Border. Liaoning Great Wall was administered by Liaodong Town. Now, it's uncommon to see its relics. The remains mainly distribute in the northwest of this region.

Ningxia Great Wall:
In Ningxia, the Sanguankou (Three Passes) Great Wall is highly recommended. In the Ming Dynasty, the Tartar and Wala tribes of Mongolia often came into the northwest China from Sanguankou. For the sake of safety, Sanguankou Great Wall was built.

Shaanxi Great Wall:
In Shaanxi, the Great Wall mainly distributes in Shenmu, Fugu, Jingbian and Hengshan in Yulin, Wuqi and Fuxian in Yanan and Dali, Heyang, Pucheng, Chengcheng, Baishui and Haicheng in Weinan. In length of more than 2,000 kilometers, Shaanxi Great Wall was built ranging from the Warring States Period to the Ming Dynasty.

Tianjin Great Wall:
The Great Wall in Tianjin was mostly built in the Ming Dynasty. And most of them were stone-structured. Only the Huangyaguan Great Wall was made up of bricks. Tianjin Great Wall has a complete defensive system, including walls, terraces, passes, fire towers, fire pools, ovens and fortresses.

2. The Construction of Great Wall
The history of the construction of the Great Wall of China can be dated back to the Western Zhou Dynasty (11th century BC - 771 BC). But the Great Wall at that time was only a line of fortresses standing to defend against attacks from the Yanyun (an ancient nomadic tribe in north China). The Period of the Warring States (476 BC - 221 BC) was an era when the seven states (Qi, Chu, Yan, Han, Zhao, Wei, Qin) were busy engaging in Great Wall construction for self-defense. Instead of one line, their walls stretched in the four directions and varied in length from several hundred miles to one or two thousand miles

In the Qin Dynasty (221 - 206 BC) the emperor Qin Shihuang ordered his laborers to connect these scattered walls and create some new sections, thus forming a Great Wall in northern and central China in the true sense. The Ming Dynasty (1368 - 1644) further developed the defensive system of the wall and strengthened it on a larger scale. It pushed the wall construction to its highest peak.
The winding Great Wall is not merely a wall but instead a complete and rigorous defense project composed of countless passes, watchtowers, garrison towns, beacon towers and blockhouses.  These fortifications were arranged in certain ways under the control of the military command system at all levels. For example, there were about 1,000,000 soldiers guarding the Ming's Great Wall. The chief military officers were stationed in garrison-towns, while lesser officials and soldiers were stationed in Guan Cheng (the defensive beachhead) and other smaller fortifications. The eleven Great Wall garrisons were set up along the Great Wall in order to guard the precinct or subsection.
The average height of the Ming Great Wall measures 33 feet and the width is about five yards. In low, flat areas the Great Wall was built high and more defense lines were added. In the lofty mountains, the wall was a little lower in order to save the human and financial cost. Sometimes, even steep cliffs served as natural walls to thwart enemies
Today, the Great Wall has lost its military function, but as a great ancient engineering work, its magnificent beauty and austere structure are still worthy appreciating.
As we all know, the Great Wall is the treasure of China - even the world. It really is a great masterpiece of mankind, with its beautiful scenes and grand construction. What many people may not know, however, is that in different periods of Chinese history the material of the Great Wall is different in different areas.
Before the use of bricks, the Great Wall was mainly built from earth, stones and wood. Due to the large quantity of materials required to construct the Great Wall, the builders always tried to use local sources. When building over the mountain ranges, the stones of the mountain were exploited and used; while in the plains, earth was rammed into solid blocks to be used in construction. In the desert, even the sanded reeds and juniper tamarisks were used to build the Great Wall.
Before and during the Qin Dynasty (221BC-206BC), because the earth buildings could withstand the strength of weapons like swords and spears and there was low technology of productivity, the Great Wall was basically built by stamping earth between board frames. As such, only walls of plain earth or earth with gravel inside were built. No fortresses were constructed along the wall, nor bricks used in the construction of gates at the passes. Some of the walls were even made only from piles of crude stones. Around Dunhuang City in Gansu Province, Yulin City in Shaanxi Province and Baotou City in Inner Mongolia, sites can still be found from the Great Wall of Qin, the Great Wall of Han and the Wall of Zhao. The Wall of Zhao was built during the Warring States Period using board frames, and the layers of earth can still be clearly seen.
During the period following the Han Dynasty (202BC-220AD), earth or crude stones were still popular building tools. The construction material did not reach a new level until the middle of the Ming Dynasty (1368-1644); however the principle of using local material was maintained. Three hundred million cubic meters (393 million yards) of earthwork were used in the construction of the Great Wall, and with the appearance of large brick and lime workshops, some parts were also built with these new materials.
Bricks were used in a lot of areas during the Ming Dynasty, as well as materials such as tiles and lime. Attempts were always made to produce the materials locally, so kiln workshops were established to burn the crude material. In a construction team there was Material Supply Department. For example, in Juyongguan Pass names of supply departments such as kiln workshops, stone ponds and material supply departments were recorded. Some materials, such as the timbers for the construction of the passes, did have to be transported from outside areas when there were none available locally.
Bricks were more a convenient material than earth and stone as their small size and light weight made them convenient to carry and thus quickened the speed of construction. Bricks are also the ideal material to bear the weight. According to a sample experiment experiencing gravity and erosion over a hundred years, the compressive strength, resistance to freezing and absorbency of the bricks of the time are similar to today's common bricks. A huge brick from a hundred years ago showed a high level of technological skill for that time. For further ease of construction, different shapes of brick were also burned and made to stuff into different positions.
Stone, however, still has its advantages. Stones cut in rectangular shapes were mostly used to build the foundation, inner and outer brims, and gateways of the Great Wall. In the Badaling section, the Great Wall is made almost entirely of granite, some of green and white stones and some of white marble. The stone material was found to better resist efflorescence than bricks.
It is not only because of the high level of productivity of the time that hard material like bricks and stones were used in the construction of the Great Wall, but also because of the development of weapons. Before the Ming Dynasty, the Great Wall was built from board frames and, although not very solid, could withhold simple weapons like swords, spears and bows. But during the Ming Dynasty, gunpowder became available. The musket, blunderbuss and cannon appeared. Due to the use of these weapons, more solid bricks and stones were required to build a stronger Great Wall.
The Great Wall of China embodies the great systems of defense created during the wars of the time; moreover it indicates a great achievement in architecture.




3. The History of China Great Wall
7 wonders of the world, Seven Wonders of the Ancient World, The Great Wall Of China, what are the wonders of the world, Wonders of the world, World Heritage Sites, In the north of China, there lies a 8,851.8-kilometer-long (5,500-mile-long) ancient wall. Now well-known as the Great Wall of China, it starts at the Jiayuguan Pass of Gansu Province in the west and ends at the Shanhaiguan Pass of Hebei Province in the east. As one of the Seven Wonders in the world, the Great Wall of China has become the symbol of the Chinese nation and its culture.
Lots of beautiful legends and stories about the Great Wall took place following along the construction, and since that time these stories have spread around the country. Those that happened during construction are abundant, such as Meng Jiangnu's story and the legend of the Jiayuguan Pass.
Meng Jiangnu's story is the most famous and widely spread of all the legends about the Great Wall. The story happened during the Qin Dynasty (221BC-206BC). It tells of how Meng Jiangnu's bitter weeping made a section of the Great Wall collapse. Meng Jiangnu's husband Fan Qiliang was caught by federal officials and sent to build the Great Wall. Meng Jiangnu heard nothing from him after his departure, so she set out to look for him. Unfortunately, by the time she reached the great wall, she discovered that her husband had already died. Hearing the bad news, she cried her heart out. Her howl caused the collapse of a part of the Great Wall. This story indicates that the Great Wall is the production of tens of thousands of Chinese commoners.
Another legend about the Jiayuguan Pass tells of a workman named Yi Kaizhan in the Ming Dynasty (1368BC-1644BC) who was proficient in arithmetic. He calculated that it would need 99,999 bricks to build the Jiayuguan Pass. The supervisor did not believe him and said if they miscalculated by even one brick, then all the workmen would be punished to do hard work for three years. After the completion of the project, one brick was left behind the Xiwong city gate. The supervisor was happy at the sight of the brick and ready to punish them. However Yi Kaizhan said with deliberation that the brick was put there by a supernatural being to fix the wall. A tiny move would cause the collapse of the wall. Therefore the brick was kept there and never moved. It can still be found there today on the tower of the Jiayuguan Pass
In addition to the above-mentioned stories about the construction of Great Wall, there are also plenty of stories about current scenic spots. A famous one is the legend of the Beacon Tower. This story happened during the Western Zhou Dynasty (11th century BC-711 BC). King You had a queen named Bao Si, who was very pretty. King You liked her very much, however Bao Si never smiled. An official gave a suggestion that setting the beacon tower on fire would frighten the King's subjects, and might make the queen smile. King You liked the idea. The subjects were fooled and Bao Si smiled at the sight of the chaos. Later enemies invaded Western Zhou, King You set the beacon tower on fire to ask for help. No subjects came to help because they had been fooled once before. Thus, King Zhou was killed by the enemy and Western Zhou came to an end.
Beautiful stories and legends about the Great Wall help to keep alive Chinese history and culture. In each dynasty after the building of the Great Wall, many more stories were created and spread.

4. The Protection of China Great Wall.

In July 2009, TravelChinaGuide (abbr. TCG) sent a survey group to investigate the Great Wall situation in Shandan County, Zhangye City, Gansu Province. This is our second visit to the Great Wall located in that place after 2002. We found the situation of the Great Wall is not optimistic. Compared to the wall pictures taken in 2002, many sections have become shorter, smaller or disappeared. The Great Wall is in danger!
Mention of the Great Wall of China evokes an image of a huge dragon flying freely on beautiful mountains. Unfortunately, this great image exists only in the well-protected Great Wall scenic areas, such as theBadaling Great Wall, Mutianyu Great Wall, and Simatai Great Wall. Most other sections lie broken in remote vast grasslands and boundless deserts, exposed to thousands of years of rains, snows and winds. Many were swallowed by sand before becoming known to the world. The matter of protecting the Great Wall cannot be delayed.
The Great Wall, owing to its huge bulk, long length and variant construction materials, is difficult to protect well compared to other relics which can be kept in museums. Besides natural disasters such as storms and earthquakes, the wall also suffers from human sabotage. There are four primary types of man-made sabotages. The first is the taking of bricks, earth and stones from the wall for constructional materials. The second is modern construction (such as the highway building) that develops at the price of damaging the wall. The third is damage  caused by tourism access development. In recent years, people have learned the importance of wall protection. Since they innocently repair the wall according to their own imagination without concern for its historical appearance, this is also considered a kind of damage.
Being one of the world cultural and natural heritages, the Great Wall of China, belongs to the world, so everyone has the responsibility to protect it. Visitors should behave themselves on the wall, never defacing the bricks, never moving the bricks and never throwing litter about. People who live near the wall should not take bricks, stones and earth from the wall to build their own houses, or dig in the wall for sheepfolds or latrines. Officials should complete and enforce relevant regulations and laws. In September of 2006, the State Council promulgated the regulation on the protection of the Great Wall which went into effect on December 1 of the same year.


5. Tourism Value of China Great Wall.
“The Great Wall of China” is one of the natural wonders of  the world, so it attracts many tourist.
The following are some images which is the evidences for The Great Wall of China’s attractiveness.

6. Advices for Tourist traveling to China Great Wall.
The Great Wall offers a timeless charm to tourists, but scenery varies with seasons. Visit it in different time you will get a quite different scene.
For Beijing Sections
Most of the popular sections of the Great Wall are located around Beijing, so the following is written with Beijing's climate in mind, although temperatures are likely to be colder and rainfall more as the Great Wall is on the mountains.
Spring
In spring, when trees and plants turn green, the wall wanders among the lush vegetation. Every thing looks so fresh. It is a good time to avoid the tourist crowds in summer and autumn. Expect temperatures from 10 to 25ºC (50-77ºF).
Summer
Summer comes and the blooming flowers and colored leaves dot the mountains. The Great Wall snakes its way like a silver necklace, standing out clearly in the strong mountain sunlight. The Beijing Great Wall usually enjoys blue skies and temperatures over 25ºC (77ºF) in summer. However, July and August are the months when most of the year's rain falls, so bring waterproofs in case.
Fall
When fall comes, the mountains are blanketed by colors of red, golden, yellow and brown, creating an amazing view and the weather during this time is pleasant. ( See best places to see fall colors in Beijing) This season is often recommended as the best season to visit. Expect temperatures from 10 to 20ºC (50-68ºF).
Winter
The mountains and the wall itself are often covered with snow in winter, offering an awesome snowy scene. The weather in this time of the year will be freezing or very cold and tourists are much fewer. Expect temperatures from 0 to 10ºC (32-50ºF). During the Chinese New Year period (uaually takes place in late January and early February), the Badaling Section of the wall is crowded with Chinese tourists.
