The Yangtze is not like rivers in Taiwan. Because of geographic factors, rivers in Taiwan are fast and have sharp drops. They fill up rapidly as soon as it rains, and are not suitable for boating or transport. But the mainland lives on its waters.
長江和台灣的河流不一樣，台灣因為地形關係，河流急、落差大，一下雨就暴漲，不能划船、運貨；大陸就真地是靠水吃飯、靠水生活。
