The flagpole is the backbone of China people. What is the Great Wall? What is the Yellow River?

The Great Wall is the pride of China people: the Yellow River is the mother river of China people.

The history of the construction of the Great Wall can be traced back to the Western Zhou Dynasty, and the famous allusion "bonfire drama princes" happened in Haojing, the capital (now Xi 'an, Shaanxi) originated from this.

During the Spring and Autumn Period and the Warring States Period, countries competed for hegemony and defended each other, and the construction of the Great Wall entered its first climax, but the construction length at this time was relatively short. After Qin destroyed the six countries and unified the world, Qin Shihuang connected and restored the Great Wall of the Warring States Period, which was called the Great Wall of Wan Li? . The Ming Dynasty was the last dynasty to overhaul the Great Wall, and most of the Great Wall seen by people today was built at this time.

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 complementarity.

It also plays an important role in mediating the two economies and making the agriculture and animal husbandry economy develop in the direction of mutual assistance. Therefore, the Great Wall not only plays the role of isolating the two economies and cultures, but also shoulders the heavy responsibility of closely linking the two economies and cultures.

The Yellow River is the most important birthplace of Chinese civilization. People in China call it "Mother River". Every year,1600 million tons of sediment is produced, of which1200 million tons flows into the sea, and the remaining 400 million tons remain in the lower reaches of the Yellow River for many years, forming an alluvial plain, which is beneficial to planting.

Extended data:

The mother rivers of China are the Yangtze River and the Yellow River. The Yangtze River is the third longest river in the world, second only to the Nile River in Africa and the Amazon River in South America, and its water volume ranks third in the world. The total area is 6.5438+0.8 million square kilometers (excluding Huaihe River Basin), accounting for about 654.38+0/5 of the total land area in China.

The Yellow River is the second longest river in China. Originated in the Yuegu Zonglie Basin at the northern foot of Bayankala in Qinghai Plateau, it winds eastward, crosses the Loess Plateau and the Huanghuaihai Plain, and flows into the Bohai Sea. The total length of the main stream is 5464 kilometers, and the water level drop is 4480 meters. The total basin area is 795,000 square kilometers (including 42,000 square kilometers of internal flow area).

When the Great Wall was built, there were nearly ten million soldiers and civilians in Qin and Han Dynasties. While building the Great Wall, Qin Shihuang began to strengthen the development and construction of border areas, which opened the prelude to stationing farmland to defend the border 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.

Immigrants and soldiers guarding the Great Wall cultivated wasteland together, which not only accelerated the economic development of the border region, saved a lot of government military expenditure, but also greatly reduced the pain of long-distance transportation and made Chinese culture spread farther and wider.
