Journey of a river

The video explores the Yangtze River, one of the longest and busiest rivers globally. It starts in Shanghai, where the river meets the East China Sea, and follows its course from the source in the mountains to its mouth. The river's journey is divided into three sections: the upper course, where it begins as a trickle; the middle course, where it widens; and the lower course, where it gently flows into the sea. The video also explains key terms like source, tributary, and mouth, highlighting the river's role in transportation and its numerous tributaries.
