内河
How to Understand
内河 refers to a river that flows entirely within the boundaries of a country, typically not connecting to the sea. It differs from a 'coastal river' or 'international river' which may cross borders or connect to the ocean.
The character 内 (nèi) means 'inside' or 'interior,' and 河 (hé) means 'river.' Together, they describe rivers that are located within a nation's interior, often playing important roles in local transportation and trade.
内河 is commonly used in geographical and environmental contexts. In China, for example, the Yangtze River has significant inland sections that support shipping and agriculture. Understanding 内河 helps learners grasp the distinction between internal and external waterways in Chinese geography.
