The Vietnamese word "biểu ngữ" translates to "banner" in English. It is a noun used to refer to a piece of cloth or similar material that displays a message, slogan, or design, often used in demonstrations, parades, or advertising.
While "biểu ngữ" primarily means "banner," it can also refer to a slogan or catchphrase that captures the essence of a movement, campaign, or idea. In this sense, it transcends the physical object and embodies the message it represents.
