The Grand Canal is the longest man-made waterway that runs north and south in eastern China. It took 6 years to build the canal. The canal was finally completed in 609 AD. The canal stretches over 1,100 miles from the city of Beijing to the city of Hangzhou. Sometimes, it is also called the Beijing-Hangzhou Canal. The canal also connects the two major rivers of China: the Yellow River and the Yangtze River. The canal was built to transport grain from the rich farms in southern China to the capital-city, Beijing.
