Of all the canals in the entire world, the Grand Canal found in China is not only the oldest, but also the longest. In fact, this canal surpasses the second and third largest canals put together, being the Panama Canal and the Suez. The Grand Canal was first brought under construction during the Wu Dynasty in 486 BC. Then it was extended during the Qi Dynasty and then again during the Sui Dynasty under the reign of Emperor Yangdi.
Today, the length of the Grand Canal is approximately 1,200 miles long, running from Hangzhou in the Zhejian province located in the south of China to Beijing, located in the northern portion of the country. Additionally, the Grand Canal connects a number of river systems to include the Yangtze, Yellow Huaihe, Quiantang, and Haihe Rivers, and then at the southern end, flows through Hebei, Tianjin, Beijing, Jiangsu, Shandong, and Zhejiang.
