History
"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.
Unlike the earlier Qin fortifications, the Ming construction was stronger and more elaborate due to the use of bricks and stone instead of rammed earth. As Mongol raids continued periodically over the years, the Ming devoted considerable resources to repair and reinforce the walls. Sections near the Ming capital of Beijing were especially strong.[7]
During 1440s-1460s, the Ming also built a so-called "Liaodong Wall". Similar in function to the Great Wall (whose extension it, in a sense, was), but more basic in construction, the Liaodong Wall enclosed the agricultural heartland of the Liaodong province, protecting it potential incursions by Jurched-Mongol Oriyanghan from the northwest and the Jianzhou Jurchens from the north. While stones and tiles were used in some parts of the Liaodong Wall, most of it was in fact simply an earth dike with moats on both sides.[8]
Towards the end of the Ming Dynasty, the Great Wall helped defend the empire against the Manchu invasions that began around 1600. Under the military command of Yuan Chonghuan, the Ming army held off the Manchus at the heavily fortified Shanhaiguan pass, preventing the Manchus from entering the Chinese heartland. The Manchus were finally able to cross the Great Wall in 1644, when the gates at Shanhaiguan were opened by Wu Sangui, a Ming border general who disliked the activities of rulers of the Shun Dynasty. The Manchus quickly seized Beijing, and defeated the newly founded Shun Dynasty and remaining Ming resistance, to establish the Qing Dynasty.
Under Qing rule, China's borders extended beyond the walls and Mongolia was annexed into the empire, so construction and repairs on the Great Wall were discontinued. (1)"

My school took the foreign language students to the great wall on saturday. It was the most touristy part of the wall called badaling. there were so many people there but also the highest point of the wall lies in this part as well. parts of the wall were so steep that it hurt my ankles to climb up and i didnt even try to get to the top most part! there were rails everywhere so people could hold onto just incase they thought they might fall. this part of the wall has also been renovated so its not as old looking as other parts (so i have been told). my friend told me also that if you carve your name on the stone on the great wall you will live a long life. so i did! he told me that the emperor who built the great wall wanted to live a long life and never die and that is where the superstition comes from. you could also take the cable car up if you didnt want to climb up.
我的学校请我们汉语留学生去长城. 这个地方有最多的游客所以有的地方是特别拥挤. 在这儿也是长城的最高的地方. 有的地方是太陡,所以我爬上去的时候让我的踝很痛.我没爬爬到长城的高峰.在没个地方有扶手所以如果你自己不能爬坡你可以幅着走.听说这个地方也盖修了所以没有别的地方看起来那么老.在长城很多人把他们的名字切片在石头上.我的朋友告诉我如果你把你的名字切片在长城的石头上可以让你的生命很富有很长.所以我写么的名字在一个石头上!我的朋友也告诉我这个故事是因为盖长城的皇帝想有一个很长的生命所以人们以为如果你也想有一个长的生命你应该写你的名字在长城的石头上.如果你不想爬上去你也可以做做缆车上去.
