By comparing the Sui Canal with the Yuan Canal, this paper expounds the similarities and differences in their layout and their practical significance.

The excavation and evolution of the Beijing-Hangzhou Grand Canal can be roughly divided into three stages: ① 1 canal. The embryonic period of the canal. In the 10th year of the Spring and Autumn Period (486 BC), Fu Cha, the king of Wu, dug a ditch in Yangzhou to connect the Yangtze River and Huaihe River. In the Warring States period, large ditches (from Yuanyang County, Henan Province, from north to south, into Putian, east of Zhengzhou City) and gaps were dug one after another, thus connecting the Yangtze River, Huaihe River and four rivers in the economic zone. (2) The second canal. Mainly refers to the canal system of Sui Dynasty. Taking Luoyang in the east as the center, Tongji Canal was dug in the first year of Daye (605) to directly communicate with Huanghuai traffic. And transformed the Hangou and Jiangnan Canal. In three years, Yongji Canal was dug again, leading to Zhuo Jun in the north. Coupled with the Guangtong Canal dug in 584 AD, a number of canal systems were formed. When I arrived in (Yang Guang), it was said that in order to go to Yangzhou to see the Qionghua, the city flower of Yangzhou, and to transport grain from the south to the north, a canal was dug from Jinghuai section to Jiangnan, with a total length of more than 2,000 kilometers. In the Yuan Dynasty, most of the capital of the Yuan Dynasty (now Beijing) had to dig canals to transport grain from the south to the north. For this reason, three sections of rivers have been dug successively, and the horizontal canal of the Sui Dynasty with Luoyang as the center has been built into a vertical grand canal with Dadu as the center and Hangzhou as the south. According to the geographical location, the Beijing-Hangzhou Grand Canal is divided into seven sections: from Beijing to Tongzhou District, it is called Tonghui River, with a total length of 82 kilometers (this length seems incredible, because my family lives in Tongzhou and works in Beijing, so it is impossible to have 82 kilometers. In addition, what is the definition of Tonghui River? Where does it start and where does it end? ); Tongzhou District to Tianjin is called the North Canal, which is 186 km long. Tianjin to Linqing is called the South Canal, which is 400 kilometers long. Linqing to Taierzhuang is called Lu Canal, which is about 500 kilometers long. Taierzhuang to Huaiyin is called the Central Canal, with a total length of 186 km. Huaiyin to Guazhou is called the Li Canal, which is about180km long. Zhenjiang to Hangzhou is called Jiangnan Canal, which is about 330 kilometers long. Yangzhou is a famous Li Canal city. When Yang Di dug a canal in Yangzhou, Yangzhou became the hub of north-south traffic. Thanks to grain transportation, it has become one of the most prosperous areas in China. The Sui Dynasty was divided into four sections: (1) Yongji Canal (2) Tongji Canal (3) Hangou Canal (4) Jiangnan River (3) Phase III Canal. Mainly refers to the Yuan, Ming and Qing Dynasties. The key areas excavated in Yuan Dynasty are Sishui to Weihe and Dadu to Tongzhou in Shandong. In 18 (128 1), Jeju River was opened, with a total length of 75km from Rencheng (Jining) to Anshan (Dongping). In 26 AD (1289), Tonghe was held, with a total length of 125km, from Nankai Canal in Shanxi, from northwest Shouzhang to Linqing. In 29 AD (1292), the Huihe River was opened, introducing Pingzhushui from Xichang, Beijing to Dadoucheng, and flowing eastward to Tongzhou to join the Baihe River, with a total length of 25 kilometers. In the 30th year of Yuan Dynasty (1293), the Grand Canal was fully navigable in Yuan Dynasty, and the waterwheel could go directly from Hangzhou to Dadu, becoming the predecessor of the Beijing-Hangzhou Canal. In the Yuan Dynasty, the whole process can be divided into seven sections: (1) Tonghui River; (2) North Canal; (3) South Canal; (4) Lu Canal; (5) the middle canal; (6) Li Yunhe; (7) Jiangnan Canal. /wenda/thread?
