In Chinese culture, which often prioritizes social harmony (和谐, héxié) and “face” (面子, miànzi), the act of 忽略 can be a subtle but powerful social tool. Unlike the directness often valued in Western cultures, deliberately choosing to 忽略 a minor mistake or an awkward comment can be a way to show politeness and protect someone's dignity. For instance, if a colleague makes a small error in a presentation, a manager might 忽略 it in public to avoid embarrassing them, addressing it privately later. This is different from the Western concept of “letting it slide,” which is often about casualness; in the Chinese context, it is a more conscious act of preserving social grace. Conversely, being 忽略'd by someone, especially a superior or an elder, can feel like a significant slight. It can imply that you are not considered important. The act of ignoring someone or their input carries social weight and can be a passive way of communicating disapproval or disinterest.
忽略 is a common word used in both formal and informal settings. Its connotation depends entirely on the context.
A common point of confusion for learners is the difference between 忽略 and other words related to inattention.
