This metaphor originates from the Buddhist concept of "three lives (past, present and future)", and borrows the image of a butterfly transforming from a chrysalis into a butterfly and fluttering around again, which is a metaphor for a person who chases after materialistic desires in the world, and is trapped by the world, and who is often caught up in the troubles and pains of the world and cannot get out of them.
In modern society, the red dust butterfly often describes the phenomenon of chasing fame and fortune, utilitarianism, and material supremacy.
