流入

流入 means 'to flow into' or 'to enter by flowing.' It describes the movement of liquids, people, or abstract concepts like information or money into a place or system.

The character 流 (liú) means 'to flow,' and 入 (rù) means 'to enter.' Together, they create a compound verb that emphasizes the action of something moving into a destination in a continuous or gradual manner.

流入 is commonly used in both literal and metaphorical contexts. For example, it can describe water flowing into a river, people migrating into a city, or data entering a network. It often implies a natural or ongoing process rather than a sudden change.
