The Yangtze, Asia’s longest river at 6,300 km, traverses China from west to east, passing through eight provinces and cities including Chongqing, Wuhan, and Shanghai. Historically and economically significant, it irrigates a large part of the country and is crucial to its agricultural production. Its Yunnan stretch, famed for its impressive parallel gorges, is a UNESCO World Heritage site and home to the Three Gorges Dam, the largest in the world.
