The Grand Canal, a monumental feat of engineering, stretches over 1,104 miles across China, linking the Yellow River and the Yangtze River. This ancient waterway, the longest in the world, has played a crucial role in China's history, facilitating trade and cultural exchange between the northern and southern regions of the country. The section that runs through Tianjin, known as the Southern Grand Canal, is a vital part of this network, contributing to the city's development as a major port and industrial hub. Recognized as a UNESCO World Heritage Site, the Grand Canal is not only a testament to China's historical ingenuity but also continues to be an important waterborne transport route today.
