The Grand Canal (Chinese: 大运河; pinyin: Dà yùnhé) is a system of interconnected canals linking various major rivers and lakes in North and East China, serving as an important waterborne transport infrastructure between the north and the south during Medieval and premodern China. It is the longest artificial waterway in the world and a World Heritage Site.
The Grand Canal has undergone several route changes throughout history. Its current main stem, known as the Jing–Hang Grand Canal, is thought to extend for 1,776 km (1,104 mi) linking Beijing in the north to Hangzhou in the south, and is divided into 6 main subsections, with the southernmost sections remaining relatively unchanged over time. The Jiangnan Canal starts from the Qiantang River at Hangzhou's Jianggan District, looping around the east side of Lake Tai through Jiaxing, Suzhou and Wuxi, to the Yangtze at Zhenjiang; the Inner Canal from Yangzhou across the Yangtze from Zhenjiang, going through the Gaoyou Lake to join the Huai River at Huai'an, which for centuries was also its junction with the former course of the Yellow River; the Middle Canal from Huai'an to Luoma Lake at Suqian, then to the Nansi Lakes at Weishan; the Lu Canal from the Nansi Lakes at Jining and into the present course of the Yellow River at Liangshan, splitting off downstream at Liaocheng's Dong'e County before continuing to the Wei at Linqing; the Southern Canal (named for its location within Hebei) from Linqing to the Hai River at Tianjin; and the Northern Canal from Tianjin to Tongzhou on the outskirts of Beijing. As such, it passes through the provinces of Zhejiang, Jiangsu, Shandong, Hebei, and the municipalities of Tianjin and Beijing. In 2014, the Chinese government and UNESCO recognized the Eastern Zhejiang Canal from Hangzhou to Ningbo along the former Tongji and Yongji Canals also as official components of the Grand Canal.
