The Vietnamese word "hoen gỉ" refers to something that is stained and rusty. It is often used to describe metal objects that have developed rust due to exposure to moisture and air over time. The term can also be used metaphorically to describe things that have become dirty or tarnished in a broader sense.
In more advanced contexts, "hoen gỉ" can be used metaphorically to describe ideas or concepts that have become outdated or have lost their value. For example: - "Những tư tưởng hoen gỉ không còn phù hợp với thời đại hiện nay." - (Outdated ideas are no longer suitable for the current era.)
While "hoen gỉ" primarily refers to rust and stains, in certain contexts, it can also imply neglect or deterioration more generally. For example, if someone's skills or knowledge are described as "hoen gỉ," it means they may be outdated or in need of refreshing.
