The Sui Canal, with Luoyang as the center, starts from Zhuo Jun in the north and reaches Yuhang in the south, with a total length of more than 2,000 kilometers. It is divided into four sections: Yongji Canal, Tongji Canal, Shanyangdu (Hangou) and Jiangnan. It is one of the most magnificent projects in the world, connecting five major water systems: Yellow River, Yangtze River, Haihe River, Huaihe River and Qiantang River. The length of the canal is second to none in the world, and the depth, width and navigation capacity of the river are the largest. The canal was opened, and "business trips are coming and going, and ships are endless." Tang Piri Xiu said, "It is beneficial and rich for fishermen in Zhuo Jun County in the north to move to Jiangdu in the south!" (Pi Wen Zi's Distinguishing Heming). "Looking back on the past by the Bian River" (Pi Rixiu) says: "The Sui Dynasty lost me thousands of miles." Like the Great Wall, the Grand Canal enjoys a high reputation in the world, which embodies the intelligence and creativity of the working people in ancient China.

After the canal was opened to traffic, it not only became a political, economic and cultural link between the north and the south, but also became a hub to communicate the "Silk Road" in the inland of Asia and the "Silk Road" at sea. The navigation of the canal also promoted the development of towns and industries in coastal areas. It is also like a ribbon, and coastal towns are like pearls inlaid on the ribbon. Since then, successive dynasties have continuously dredged and reconstructed the canal, making it continue to play the role of connecting the north and south arteries. The opening of the canal promoted the development of the city, and Jiangdu, Yuhang and Zhuojun flourished rapidly. It has safeguarded national unity and promoted centralization and stability.
