The Great Wall of Wan Li is a huge national defense project built by various countries in the long years amid internal disputes in ancient China.

The Great Wall is an ancient defense project with the longest construction time and the largest engineering quantity not only in China, but also in the world. Since the Western Zhou Dynasty, it has been continuously built for more than 2, years, distributed in the vast land in northern and central China, with a total length of more than 2, kilometers.

since Qin Shihuang, almost all dynasties that ruled the Central Plains have built the Great Wall. More than ten dynasties, including Han, Jin, Northern Wei, Eastern Wei, Western Wei, Northern Qi, Northern Zhou, Sui, Tang, Song, Liao, Jin, Yuan, Ming and Qing, all built the Great Wall in different scales.

judging from the ruling nationalities who built the Great Wall, besides the Han nationality, many dynasties in which ethnic minorities ruled China also built the Great Wall, and there were more than those ruled by the Han nationality. During the Kangxi period of Qing Dynasty, although the construction of the Great Wall was stopped on a large scale, it was later built in some places. It can be said that the construction of the Great Wall has not stopped for more than 2, years from the Spring and Autumn Period and the Warring States Period to the Qing Dynasty.

Significance of the Great Wall:

From the Qin and Han Dynasties to the Ming and Qing Dynasties, many passes along the Great Wall became places or centers for ethnic transactions in the two major economic and cultural systems of agriculture and animal husbandry, and some gradually developed into important towns along the Great Wall. The Great Wall not only ensures the normal development of agricultural economy, culture and animal husbandry economy and culture, but also provides a place and convenience for their exchange and mutual supplement.

it also plays an important role in mediating the two economies and making the agricultural and animal husbandry economies develop in the direction of mutual cooperation between the main and the auxiliary. Therefore, the Great Wall not only played the role of separating the two economies and cultures, but also shouldered the heavy responsibility of closely linking the two economies and cultures.

during the Qin and Han dynasties, there were nearly 1 million soldiers and civilians. While building the Great Wall, Qin Shihuang began to strengthen the development and construction of border areas, which opened the prelude to stationing fields to defend the border areas and developing the border areas. Because it took a long time to build the Great Wall in the Han Dynasty, many people put forward suggestions on immigration, which were adopted and implemented by the Han government.

Together with the soldiers guarding the Great Wall, the immigrants reclaimed wasteland for farming, which not only accelerated the economic development of the border region, saved a lot of military expenditure of the government, but also greatly reduced the pain of long-distance transportation and spread Chinese culture far and wide.
