CCTV Vintage Video: Grand Canal of China (1986)

The Grand Canal, known to the Chinese as the Jing–Hang Grand Canal (Chinese: 京杭大运河; or 'Beijing–Hangzhou Grand Canal'), a UNESCO World Heritage Site, is the longest as well as the oldest canal or artificial river in the world. Starting at Beijing, it passes through Tianjin and the provinces of Hebei, Shandong, Jiangsu and Zhejiang to the city of Hangzhou, linking the Yellow River and Yangtze River. The oldest parts of the canal date back to the 5th century BC, but the various sections were first connected during the Sui dynasty (581–618 AD). Dynasties in 1271–1633 significantly rebuilt the canal and altered its route to supply their capital Beijing.



The total length of the Grand Canal is 1,776 km (1,104 mi). Its greatest height is reached in the mountains of Shandong, at a summit of 42 m (138 ft). Ships in Chinese canals did not have trouble reaching higher elevations after the pound lock was invented in the 10th century, during the Song dynasty (960–1279), by the government official and engineer Qiao Weiyue. The canal has been admired by many throughout history including Japanese monk Ennin (794–864), Persian historian Rashid al-Din (1247–1318), Korean official Choe Bu (1454–1504), and Italian missionary Matteo Ricci (1552–1610).

In contrast, the Delaware and Raritan Canal (D&R Canal) is a canal in central New Jersey, United States, built in the 1830s, that served to connect the Delaware River to the Raritan River. It was an efficient and reliable means of transportation of freight between Philadelphia and New York City, especially coal from the anthracite fields in eastern Pennsylvania. The canal allowed shippers to cut many miles off the existing route from the Pennsylvania coal fields, down the Delaware River, around Cape May, and up along the (occasionally treacherous) Atlantic Ocean coast to New York City.
