B.c. Eleven Century, Xi-Zhou, Our country had the recordation that is "The city wall set down in the north". From B.c. Seven Century to B.c. Three Century that is called the Spring and Autumn Period and the Warring States Period, The princes of many little states began to fight and swallow up each other. They all built the long city wall for self-defence, for instance, Chu state built its wall in the Nanyang district firstly, Qi state built its wall in the Shandong province, Zhongshan state, Wei state, Han state, Yan state, Zhao state, Qin state and so on all began to build their city wall. The whole circumvallation was more than five thousand kilometers long, but each part of it was separated from each other.

B.c. 221 Year, QinShiHuang consolidated all six states, He pulled down the wall between the states one side, the other side he built the new city wall in the north to defense the Hun. He command MengTian general and thousands upon thousands people to build the new city wall, it stretch more than five thousand kilometre in an unbroken chain, which is the oldest Great Wall.

During West Han period, the Hun in the north became stronger and stronger, so the Han state had to build new circumvallation and reinforce the old Qin Great Wall. and strengthen the old Qin Great Wall. From the eastern part Liaoning province to the YuMen gate, the Great Wall is longer than ten thousand kilometers. Its scale exceeds the Qin Great Wall's. During East Han period, people built new wall inside the West Han Great Wall to defense the Serbi and the Qiang nationalities. Its length is more than five kilometers. The Great Wall built in the two Han dynasties is the largest project in Chinese history.

Since then, the nations in the north began to come into North China and central plains. They built North Dynasty, right against South Dynasty. West Wei state, East Wei state, West Qi state, and West Zhou state in North Dynasty, all built the multiple Great Wall in the north of Yellow River. The Sui Dynasty unified the whole China, and then built new circumvallation from the middle of the Yellow River to the western part of Gansu province. The wall is three thousand kilometers long and forms a new system with the eastern Great Wall.

During Tang Dynasty, power of China was so strong that all nations in the north had to submit to Tang. Hence Tang hadn't built any new wall, but built three cities to accept surrender. At the time Gaoli nation built more than one thousand kilometers of Great wall from the northeast of China to the Datong River estuary, to defense Tang.

In Zhu, Liao and Jin Period, North China was occupied by Khitan, and west parts of the Yellow River were occupied by West Xia, while North Song Dynasty just repaired Yan Gate. Since then, Liao and Jin states became stronger and stronger and occupied the whole north parts of the Yellow River, and South Song Dynasty had no ability to build any new Great Wall. But Liao-Jin regime built new Great Wall in the northeastern parts of Inner Mongolia to fight against other nations in the north. People often called it "Genghis khan City Wall".

After Ming Dynasty was founded, the archons began to build new Great Wall in the north to defense Yuan state coming back and Dadan, Waci, Nvzhen etc. And they also built many Walls in southeastern China along the coast to defense foreign enemies. Ming Great Walls are most in Chinese history. Its main part begins from Yalu River to Jiayu Gate, and its length is more than seven thousand kilometers. Therefore, the part from ShanHai Gate to JiaYu Gate is kept best.

At the beginning of Qing Dynasty, in the Liaoning and Jilin Province people built the ShengJing city wall which was 2600 kilometers long. And the people also repaired the ShanHai, JuYong, YanMen, JiaYu Gate etc. But from the metaphase of Qing Dynasty, the Great Wall was not repaired more.

Now under weathering and man-made destroy, many parts of the Great Wall have become very slipshod, even including Ming Great Wall. But the Great Wall, more than a hundred thousand kilometers long, is a huge Chinese dragon and the best, greatest and grandest work in the whole human history. It also materializes architectural skills. Now the people inside and outside the Great Wall, through the long-term traffics, have united into one big family. The Great Wall is the symbol of China and Chinese pride. It also can promote friendship between Chinese and foreigners.
