The Beijing-Hangzhou Grand Canal is a great project created by the working people in ancient China, a precious material and spiritual wealth left by our ancestors, and an important living and flowing human heritage. The Grand Canal originated in the Spring and Autumn Period, formed in the Sui Dynasty and developed in the Tang and Song Dynasties. The Beijing-Hangzhou Grand Canal was built in the Spring and Autumn Period more than 2,000 years ago, with a history of 2,500 years. An important river channel dug by Qin Shihuang (Ying Zheng) in Jiaxing also laid the foundation for the development of Jiangnan Canal in the future. According to Yue Jue Shu, Qin Shihuang "ruled Lingshui Road from Jiaxing, crossed Qiantang River and crossed Zhejiang". About 2,500 years ago, Fu Cha, the king of Wu, dug a ditch, opened a canal connecting the Yangtze River and Huaihe River, and built Seoul, from which the canal and its culture were derived. The Grand Canal we are talking about today was dug in the Spring and Autumn Period, completed in the Sui Dynasty, flourished in the Tang and Song Dynasties, straightened in the Yuan Dynasty, and dredged in the Ming and Qing Dynasties (dug in 486 BC and opened to traffic in A.D. 1293), which lasted 1779. In the long years, it has experienced three major construction processes. During the Sui Dynasty, Yang Di used millions of people to dig the Grand Canal, which made great contributions to the unprecedented prosperity of the country's economy and culture. After the development in Tang and Song Dynasties, it finally became a traffic artery connecting the five major water systems of Haihe River, Yellow River, Huaihe River, Yangtze River and Qiantang River in Yuan Dynasty. Stands for artificial Tianhe. The Grand Canal is the second "golden waterway" in China after the Yangtze River. Its value is comparable to that of the Great Wall, and it is the earliest and longest artificial river course in the world, which is 16 times that of Suez Canal and 33 times that of Panama Canal. The Beijing-Hangzhou Canal has always been the main canal for water transportation in past dynasties, and played an important role in the economic and cultural exchanges between the North and the South. /kloc-shipping rose in the 0/9th century. With the opening of the Jin-Pu Railway, the role of the Beijing-Hangzhou Canal gradually decreased. After the migration of the Yellow River, the water resources in the reach of Shandong Province were in short supply, and the siltation was shallow, and the north-south navigation was cut off and silted up to the ground. The section of Jiangsu with large water volume and good navigation conditions can only sail in Xiao Mu. The abandonment and depression of the Beijing-Hangzhou Canal is a portrayal of the semi-colonial and semi-feudal system in China. After liberation, some river sections were widened and deepened, many modern docks and shiplocks were built, and shipping conditions were improved. Seasonal navigation mileage reaches 1 100 km or more. 660 kilometers south of Pixian County, Jiangsu Province, the 500-ton fleet can be unimpeded. The ancient Beijing-Hangzhou Canal will become a water conveyance channel for the future South-to-North Water Transfer Project. The bottom line is: a lot of people were used at that time, and it was found that the loss was great. It was built at that time and will benefit in the future. Look at what I said. Give it to me. Thank you.
