下游

下游 refers to the downstream direction of a river or stream, or a location further along a process or system. It is often used in both literal and metaphorical contexts.

The character 下 (xià) means 'down' or 'below,' while 游 (yóu) originally meant 'to swim' or 'to float.' Together, they suggest movement or position in a downward direction, especially in water flow.

In daily life, 下游 is commonly used in geography, environmental discussions, and even in business or technology contexts to describe a later stage or location. For example, it might refer to a factory downstream from a pollution source or a user who receives content after it has been processed.
