The Vietnamese word "biêng biếc" is an adjective often used to describe something that is bright, beautiful, or vibrant, particularly in terms of colors. It can refer to various things, such as the sky, leaves, or flowers, and it conveys a sense of liveliness and freshness.
In more advanced contexts, "biêng biếc" can be used metaphorically to describe a person's lively spirit or an atmosphere that feels cheerful and uplifting. - Example: "Nụ cười của cô ấy biêng biếc như hoa nở." (Her smile is as bright as blooming flowers.)
Though primarily used to describe beauty and brightness, in some contexts, "biêng biếc" can also imply a sense of nostalgia or longing, especially when referring to memories that feel vivid and lively.
