1.The History of the GrandCanal of China
1.1 The Spring and Autumn Period
The Grand Canal was first built in 486 B.C. in Spring and Autumn Period for the military utilization, which was called “Hangou” in Yangzhou connecting the Yangtze River and Huai River. And it is the oldest section of the later Grand Canal. In this phase, the Canal mostly used the natural lakes, including Wuguang Lake, Luyang Lake, Fanliang Lake, Bozhi Lake and Sheyang Lake.

1.2 The Sui and Tang Dynasties
The canal comprised four sections:Yongji canal, Hangou canal, Tongji canal and Jiangnan canal. They were dug in Sui Dynasty and perfected, dredged up in Tang Dynasty.
1.3Yuan, Ming and Qing Dynasties
A summit section was dug across the foothills of the Shandong massif during the 1280s, shortening the overall length by as much as 700 km
In Ming Dynasty, The Grand Canal was repaired on the basis of the Canal in Yuan Dynasty. The Grand Canal was separated from the lakes by building levees. And the management system of the Grand Canal was perfect and effective
In Qing Dynasty(1636~1911) , the Grand Canal continued to function. But after 1826, the Yellow River’s sand gradually silted the canal. In 1855, the Yellow River flooded in Tongwaxiang, Henan Province and the Grand Canal between Anshan and Linqing was broken. In 1905, the transportation stopped.
1.4 After 1958
During 1950s-1970s, the government employed labors to dredge the old canals and dig new canals and also build some large locks. Therefore
the Grand Canal from Hangzhou to Jining began to shipping again
2. The characteristics of the Grand Canal
2.1 The span of time and space is large
The Grand Canal has a history of near 2500 years, which was first dug in 489 B.C. in Spring and Autumn Period.
The Grand Canal is 1794km, across 33 cities from Hangzhou to Beijing. It connects five rivers: Qiantang River, Yangtze River, Huai River, Yellow River and Haihe River. It’s the longest canal in the world, which is 11 times as long as Suez Canal, and 22 times as long as Panama Canal.

The Grand Canal is “a great civil engineering represents the Chinese civilization and technology” ——Joseph Needham
the Grand Canal and Canal du Midi of France were listed as the “Technologically significant canals” both with 11 scores which is the highest and the next is Rideau Canal of Canada.(TICCIH, 1995)

（2）In Ming Dynasty, the Grand Canal between Yangzhou and Huaian was separated from the lakes by building stone levees. So the boat can travel in the canal safely without the risk of the storms of the lakes.
