What are the names of ancient projects?

1, Wan Li Great Wall: During the Spring and Autumn Period and the Warring States Period, countries built the Great Wall in dangerous places to resist foreign enemies. After Qin Shihuang destroyed the six countries and completed reunification, the Great Wall in the northern part of Qin, Zhao and Yan was restored and unified, and it was called "Wan Li Great Wall".

2. Beijing-Hangzhou Grand Canal: It is the earliest and longest artificial canal in the world. It starts from Beijing in the north and reaches Hangzhou in the south, with a total length of about 1, 747 kilometers. It is a great project as famous as the Great Wall of Wan Li.

Shanhaiguan: Also known as Guan Yu, it is the starting point of the Great Wall in Qinhuangdao City, Hebei Province. It borders Jiao Shan in the north and Bohai Sea in the south, connecting North China and Northeast China. When the situation is eradicated, it is known as "the first level in the world".

4. Jiayuguan: It is the end of the Great Wall in the west of Jiayuguan City, Gansu Province, at the southern foot of Jiayu Mountain. Lanzhou-Xinjiang Railway passes through here, which is the main road of east-west traffic.

5. Sui Grand Canal: the predecessor of Beijing-Hangzhou Grand Canal. From 605 to 6 10, Yang Di recruited millions of people and opened a grand canal running through the north and south. The Grand Canal, centered on Luoyang, reaches Zhuo Jun in the north and Yuhang in the south, and flows through today's vast areas of Hebei, Shandong, Henan, Anhui, Jiangsu and Zhejiang. This is the longest canal in the ancient world. "I died in this river, and thousands of miles depend on Tongbai."

6. Dujiangyan: Dujiangyan is located on the Minjiang River in the west of Chengdu Plain. It was built in the last years of King Zhao of Qin. It is a large-scale water conservancy project organized by Li Bing and his son, the magistrate of Shu County, on the basis of previous excavations, and has been playing the role of flood control and irrigation. It is the oldest, only surviving and still in use in the world, and it is a grand water conservancy project characterized by dam-free water diversion.

7. Lingqu is located in Xing 'an, Guangxi Zhuang Autonomous Region, and was opened to traffic in 2 14 BC. Lingqu from east to west connects Haiyang River in the east of Xing 'an (the source of Xiangjiang River flows from south to north) and Darong River in the west of Xing 'an (the source of Lijiang River flows from north to south). It is one of the oldest canals in the world and has a good reputation as the pearl of ancient water conservancy buildings in the world.

8. Every project is the crystallization of diligence, courage and wisdom of our ancestors in China.
