We as Destiny girl choose The Great Wall of China as one of the great wonder of the world because of it history. Lets we show you all and lets learn about The Great Wall of China here with Destiny Girl..


First we share with you about it history, let’s check it out ..:)


"The long wall of china is a series of stone and earthen fortifications in northern China, built, rebuilt, and maintained between the 5th century BC and the 16th century to protect the northern borders of the Chinese Empire during various successive dynasties. Since the 5th century BC, several walls have been built that were referred to as the Great Wall. One of the most famous is the wall built between 220–206 BC by the first Emperor of China, Qin Shi Huang. Little of that wall remains; the majority of the existing wall were built during the Ming Dynasty.


The Chinese were already familiar with the techniques of wall-building by the time of the Spring and Autumn Period, which began around the 8th century BC. During the Warring States Period from the 5th century BC to 221 BC, the states of Qi, Yan and Zhao all constructed extensive fortifications to defend their own borders. Built to withstand the attack of small arms such as swords and spears, these walls were made mostly by stamping earth and gravel between board frames. Qin Shi Huang conquered all opposing states and unified China in 221 BC, establishing the Qin Dynasty. Intending to impose centralized rule and prevent the resurgence of feudal lords, he ordered the destruction of the wall sections that divided his empire along the former state borders. To protect the empire against intrusions by the Xiongnu people from the north, he ordered the building of a new wall to connect the remaining fortifications along the empire's new northern frontier. Transporting the large quantity of materials required for construction was difficult, so builders always tried to use local resources. Stones from the mountains were used over mountain ranges, while rammed earth was used for construction in the plains. There are no surviving historical records indicating the exact length and course of the Qin Dynasty walls. Most of the ancient walls have eroded away over the centuries, and very few sections remain today. Later, the Han, Sui, Northern and Jin dynasties all repaired, rebuilt, or expanded sections of the Great Wall at great cost to defend themselves against northern invaders.


The Great Wall concept was revived again during the Ming Dynasty following the Ming army's defeat by the Oirats in the Battle of Tumu in 1449. The Ming had failed to gain a clear upper-hand over the Manchurian and Mongolian tribes after successive battles, and the long-drawn conflict was taking a toll on the empire. The Ming adopted a new strategy to keep the nomadic tribes out by constructing walls along the northern border of China. Acknowledging the Mongol control established in the Ordos Desert, the wall followed the desert's southern edge instead of incorporating the bend of the Huang He.


With its rapidly growing infrastructure and budding economy, China is a blend of modern sophistication and rich tradition. It’s this unique combination that makes the country a popular destination. There’s the Great Wall of China and Beijing’s famed Temple of Heaven, with its white marbled, circular altar. Other popular cities include Xian, one of the oldest, and Shanghai, which this year will host the World Expo.

The oldest sections of the Great Wall in the Beijing area - parts built around 1,500 years ago - should be getting more attention, according to an authority on the ancient landmark.


Tang Xiaofeng, a professor from the center of historical geography at Peking University, made the observation while explaining his research to members of the third session of 11th Beijing municipal committee of the Chinese People's Political Consultative Committee.


Tang has been studying the most ancient sections of the wall for five years and co-wrote a book about the "forgotten sections" in the shadows of Beijing's Yanshan Mountain.


The book Report on the Ruins of the Ancient Great Wall in the Northern Mountains was published in January.


Tang said the ravages of time have ensured the wall is no longer standing but stones used in its construction remain.


"The stone blocks, which are all that is left after the walls were broken down by the constant force from the growth of plants inside the gaps, are valuable," said Tang.


He told METRO yesterday the ruins are the earliest sections of the Great Wall in Beijing's municipal area. They are 900 years older than the Ming Dynasty Great Wall.


The Great Wall was begun between 220 and 206 BC by the first Emperor of China, Qin Shi Huang. Little of that wall remains today. Most of the wall celebrated today was built during the Ming Dynasty (1369-1644).


"The ruins of the Great Wall that was built, rebuilt and maintained during the dynasties between the two periods, are often ignored by the public and government," said Tang.


Five years ago, Tang and a group of experts from the Beijing Institute of Surveying and Mapping started to map the historical geography of Beijing. During the process, they found a long, ruined, stone wall snaking along the top of a mountain.


Tang and other experts believed the ruined wall was a missing part of the Great Wall constructed during the Northern Qi Dynasty, which was one of the Northern dynasties that was in power between 550 and 577.


In 1993, a retired teacher discovered the first traces of the missing walls and wrote a book on the subject.


Local villagers also spoke of "stone fences" nearby.

Tang and his team found additional ruins on Yanshan Mountain in the following years and he believes there are probably more sections waiting to be found on the mountain.


"I am not calling on the municipal government to protect the ruins, since there is nothing to demolish, only the stones that are left behind that have witnessed so much history," said Tang. "However, there is still great research value in the history.


"For instance, I suspect the wall was used to strike awe into potential invaders from the north more than it was built for practical military defensive reasons," said Tang.


He said he would like to see the ruins explored and incorporated into a tourism site along the same lines as the Ming Dynasty Great Wall.


Beijing municipal administration of cultural heritage is planning to conduct full-scale research on the ruins of the ancient Great Wall, said Tang.
