水雾 (shuǐwù) is the Chinese word for "mist," which is a thin, fog-like water vapor that forms in the air, often near the ground. In English, we usually refer to mist as "fog," which is a type of mist that is dense enough to obscure visibility. You can use the word "mist" to describe a thin, diffuse cloud of water vapor, or you can use the word "fog" to describe a denser, more visible cloud of water vapor that is close to the ground. For example, you might say "It's a misty morning" to describe a morning where there is a thin layer of water vapor in the air, or you might say "It's very foggy today" to describe a day where there is a thick layer of water vapor in the air that is obscuring visibility.
