The Vietnamese word "ruồi muỗi" refers to two types of small flying insects: "ruồi" means "fly," and "muỗi" means "mosquito." Together, the term is often used to talk about annoying insects that buzz around, especially in warm weather.
In a more advanced context, "ruồi muỗi" can describe not just the insects themselves but the concept of small, bothersome distractions in one's work or life. For instance, you might say, "Tôi không muốn bị ruồi muỗi làm ảnh hưởng đến công việc của mình." (I don’t want flies and mosquitoes to affect my work.)
In a casual conversation, "ruồi muỗi" can refer to trivial matters or distractions. For example, if someone is focusing on minor details instead of the bigger picture, you might say they are caught up in "ruồi muỗi."
