The Grand Canal, extending from Beijing in the North to Hangzhou in the South, is the longest man-made river. Its construction was one of the most magnificent projects throughout the Chinese history. The construction of the canal started in the 4th century BC and was completed in the 13th century, with an original aim of facilitating grain transportation. Later, it was also for transporting other commodities. Over time, the areas along the course of the canal have developed into the industrial and commercial centres of China. For a long time, the canal has served a pivotal role in the booming of Chinese economy, enhancing the personnel exchange and cultural communication between northern and southern parts of the country.
