How it's used
This term is primarily used in scientific, environmental, or geographical contexts rather than in casual daily conversation. It acts as a collective noun for bodies of water such as lakes, rivers, or oceans. Speakers usually prefer specific terms like 河, 海, or 湖 when talking about a particular location in everyday life.

Common mistake
Avoid using this term to refer to a simple container of water or a drink, as it strictly denotes a geographical or ecological feature. Using it in a casual setting to describe a glass or bottle of water will sound unnatural and overly formal.
