The word "鼓吹" is formed by combining the character "鼓" (gǔ), which means "drum" or "to beat a drum", with "吹" (chuī), meaning "to blow" or "to play a wind instrument". Originally, it referred concretely to the act of performing music with drums and wind instruments, typically in ceremonies or processions. This literal sense evolved through metaphorical use to describe energetic promotion or advocacy, as such music was used to draw attention and convey messages forcefully.
